Expand all

The purpose of the Water Supply and Wastewater Bylaw 2022 is to:

protect public infrastructure from damage and misuse
protect public health, and
ensure the public water supply and wastewater networks are functioning efficiently.

The bylaw regulates some activities and behaviours to reduce the potential for contamination of drinking water, or damage to the networks that carry drinking water and wastewater.

The Water Supply and Wastewater Bylaw 2022 replaced the Water Supply, Wastewater and Stormwater Bylaw 2014, effective from 1 July 2022.

There is also a new separate bylaw covering stormwater - the Stormwater and Land Drainage Bylaw 2022.

The discharge of trade waste is covered by a separate bylaw - the Trade Waste Bylaw 2015(external link).

The Christchurch City Council makes this bylaw under sections 145 and 146 of the Local Government Act 2002.

Preamble

This preamble is explanatory and is not part of the bylaw: This bylaw replaced the water supply and wastewater parts of the Water Supply, Wastewater and Stormwater Bylaw 2014 as part of a bylaw review process, and was adopted in 2022 as a standalone bylaw.

Trade waste is covered by a separate bylaw, the Trade Waste Bylaw 2015, which regulates the discharge of trade waste and tankered waste to the wastewater system.

This bylaw contains explanatory notes, which are not part of the bylaw. The Council may add, amend or delete explanatory notes at any time without amending the bylaw.

Explanatory note: Explanatory notes are used for a number of reasons, including to explain the intent of a clause in less formal language, to include additional helpful information, or because the information may be subject to change and need to be updated before the bylaw itself has to be updated.

Part 1: Water supply

4. Objectives

The objectives of this part of the bylaw are to:
1. promote the efficient use of water, manage demand for water and protect against waste or misuse of water;
2. protect the water supply from contamination;
3. regulate the use of land, structures and infrastructure associated with the water supply system to protect these assets from damage, misuse, or loss;
4. prevent unauthorised connection to the water supply system;
5. define the obligations of the Council, installers, owners and the public in matters related to the water supply system and
6. determine the volumes of water consumed on any property for charging purposes or to locate any water leaks at the property

Explanatory note: Objectives, policies and standards relevant to this part of the bylaw can be found in the Council’s Te Wai Ora o Tāne Integrated Water Strategy, the Infrastructure Design Standards and in the consents that the Council holds for water takes for the public water supplies. The bylaw is part of how the Council can give effect to Te Mana o te Wai.

5. Approval required for connection, supply, disconnection and other works

No person may, without the Council’s written approval -
1. connect, or allow the connection of any fittings to the water supply system
2. disconnect from the water supply system
3. change the location of the point of supply
4. install an additional point of supply or supply of water
5. install cross-boundary connections
6. provide water from the Council supply to any other party or property
7. obtain a temporary water supply
8. install a connection and supply for a fire protection system or
9. install a privately-owned supply pipe on Council-owned property
A written application for approval of any matter in subclause (1) must be made in the form required, must contain all information requested and must be accompanied by the relevant fee (if any).
An authorised officer considering an application may require the applicant to provide further information, at the applicant’s cost, in order to process an approval.
The Council may impose conditions as part of an approval. Any conditions must be complied with in the exercise of the approval.
Any approval will state:
1. the type of supply (on-demand or restricted supply, and either residential, commercial or temporary supply)
2. whether or not the applicant must pay for and install a backflow prevention device approved by the Council; and
3. any other conditions related to the supply
Where a single point of supply serves more than one property, and the water supply needs to be separated, the property owner is (or property owners are) responsible for all costs associated with separating the supply, unless otherwise agreed by the Council.

Explanatory note: The requirement to separate private supplies may be triggered by subdivision, an upgrade to water supply infrastructure, or changing regulatory requirements.
Without limitation, the Council may decline approval to connect to the water supply system where, in the Council’s reasonable opinion:
1. there is insufficient capacity in the network to accommodate the connection
2. the design of the proposed connection does not meet Council standards or requirements
3. the connection is outside the area currently served by the water supply system, regardless of its proximity to any specific component of the water supply system or
4. refusal is necessary to protect the water supply system, the health and safety of any person, or the environment
Where the Council declines an application it will notify the applicant of the decision, giving reasons.
If a connection to the water supply system is not physically made within twelve months of an approval being granted, the approval will be deemed to have lapsed and a new application will be required.
Where the Council approves a disconnection:
1. the point of disconnection will be determined by the Council on a case by case basis and
2. the works must be undertaken by an authorised agent of the Council and
3. the person who has been granted approval for the disconnection is responsible for all costs of this work, including the removal of any Council-owned pipes
  
  Explanatory note: The point of disconnection is generally at the sub-main or water main, rather than the point of supply. This is to prevent ‘dead ends’ in the network and water stagnating at these points, which could result in bacteria growth that compromises the safety of the drinking water supply.
A customer with a current connection may request that the Council change:
1. the type of supply (e.g. from restricted to on demand)
2. the classification of the supply (e.g. from residential to commercial supply) or
3. the terms and conditions of supply
The Council may require a new application for any request under subclause 11.
The Council may, at any time, review a connection approval and any conditions.
Following the review, and after obtaining and considering the written views of the customer, the Council may;
1. vary or add any conditions that the Council considers necessary or
2. require a new application for connection to be submitted within the timeframe specified

6. Temporary connections

The Council may assess and recover the value of any water drawn and any other associated costs incurred by the Council for any temporary connections to the water supply system.
No person may access, or take any water from a standpipe or hydrant unless that person is -
1. an authorised agent of the Council or
2. authorised by the Council to take water from a hydrant under clause 5 or
3. approved by the Council to make a temporary connection to the water supply system or
4. operating on behalf of Fire and Emergency New Zealand, for the purpose of fighting fires, emergency management, training and testing
Any person accessing water from a standpipe must use a Council-supplied standpipe fitted with a backflow prevention device and a water meter, and pay the Council for the cost of the water supplied.

Explanatory note: Approved standpipes can be hired from Council authorised agents.

7. Restricted activities within Maintenance Access Corridors

This clause applies to parts of the water supply system that are located underground and within non-Council land. The Council requires that these parts of the water supply system are accessible in order to repair, replace, or otherwise maintain these parts of the water supply system.
This clause does not apply where there is an easement in favour of the Council registered against a Record of Title for a property that enables adequate maintenance access for the water supply system, irrespective of the width of the easement strip created by that easement.
No person may, without the Council’s written approval under this bylaw, carry out the following restricted activities:
1. build, place or install, or allow to be built, placed or installed, any building or structure (other than a boundary fence), over or within a Maintenance Access Corridor
2. lay or permit any utility service or private pipe across or along the line of an existing part of the water supply system within a Maintenance Access Corridor or
3. undertake site works within a Maintenance Access Corridor
  
  Explanatory note: Structures include temporary or relocatable buildings (such as sheds), shipping containers, storage tanks, decks, hard landscaping, etc. Each request will be considered on a case-by-case basis, taking into account the particular set of circumstances involved, and the likely access needs for maintenance. Reinstatement of areas after access for maintenance will be completed to a safe standard, and may not be to the exact prior condition (eg: it may not be possible to reinstate or match some features or finishes, such as coloured or textured concrete).
  
  Written approval for a similar purpose under a revoked version of this bylaw is considered written approval under this bylaw, in accordance with the savings provisions in this bylaw (clause 41).
  
  Any person who believes that compliance with the requirement in clause 7 would adversely affect them or their business, without a corresponding public benefit, can apply to the Council for a dispensation from compliance with this requirement under clause 13 of the General Bylaw 2008.
No person may plant any tree within a Maintenance Access Corridor that is likely to cause a nuisance or damage to any part of the water supply system.
Where the Council’s infrastructure or asset is a pipe, the Maintenance Access Corridor width is calculated by the Council as the greater of either:
1. twice the buried depth of the pipe (surface to trench base), plus the outside diameter of the pipe or
2. 1.5 metres from either side of the centre of the pipe
Where the infrastructure or asset is not a pipe, the Maintenance Access Corridor is one metre from the asset’s border in all directions (eg a manhole).

Explanatory note: The details of each specific site and the width and location of the Maintenance Access Corridor will be determined by the Council. Deeper, and usually larger, pipes require a greater area for maintenance access.

8. Applications and approvals for restricted activities within a Maintenance Access Corridor

A written application for approval of a restricted activity within a maintenance access corridor must be made in the form required, must contain all information requested, and must be accompanied by the relevant fee (if any).
An authorised officer considering an application may require the applicant to provide further information, at the applicant’s cost, in order to process an approval.
The Council may impose conditions as part of an approval. Any conditions must be complied with in the exercise of the approval.
Where the Council declines an application it will notify the applicant of the decision, giving reasons.

9. Protection of source water and the water supply system

No person, other than the Council and its authorised agents, may enter any fenced area, building, or facility set aside by the Council for the protection of source water or as a public water supply facility, without prior written approval of the Council.
No person, other than the Council and its authorised agents, may access any part of the water supply system without prior written approval of the Council, except to operate the service valve.
No person may enter, make any connection with, discharge into, tamper or otherwise interfere with any part of the water supply system without prior written approval of the Council.
Unless approved by the Council, no person may install quick-closing valves, pumps or any other equipment on any piping on the customer’s side of the point of supply which may cause pressure surges or fluctuations to be transmitted within the water supply system, or compromise the ability of the Council to maintain its levels of service. If such unauthorised devices are found, the Council will require these are removed or replaced with an acceptable valve, at the owner’s cost, to minimise potential damage to Council assets.

Explanatory note: Pressure surges, or changes in pressure, can cause contamination of the water supply and damage to the water supply system. Examples of devices that may cause surges include, but are not limited to; actuators, solenoids, large irrigators, or any other equipment causing large draw from the network.
Any person responsible for, or aware of, a chemical or hazardous substance spill within a community drinking water protection zone must immediately report the spill to the Council.

Explanatory note: Any spill within a community drinking water protection zone has the potential to contaminate source water. Examples of spills include (but are not limited to): diesel, fertilisers and pesticides. Environment Canterbury must also be notified of any such spill.
Any person intending to undertake the aerial application of any chemical in the vicinity of a community drinking water protection zone, including but not limited to, fertilisers, herbicides or pesticides, must notify the Council of the activity -
1. as soon as practicable for application of any fire-fighting chemical or
2. at least two working days prior to application for any other chemical or agricultural application
  
  Explanatory note: Notifying the Council of intended aerial spraying applications in the vicinity of Council intakes (water catchment areas) helps the Council to better mitigate any contamination risk to drinking water supplies. Environment Canterbury’s Land and Water Regional Plan controls aerial application activities, and provides setback distances for protection of community drinking water supplies. The drinking water protection zones can be viewed on Canterbury Maps.
No person may:
1. plant any tree in a position that is likely to cause a nuisance or damage to any part of the water supply system or
2. allow the roots of any tree on their property to cause damage, interference, or blockage to any part of the water supply system, or to otherwise restrict access to any part of the water supply system
Where, in the Council’s opinion, tree roots from a tree located on private property are causing damage, interference or blockage to any part of the water supply system, or are otherwise restricting access:
1. the Council may require the property owner to remove the tree or trim the roots or
2. the Council may remove the tree or trim the roots, and may seek to recover costs from the property owner

Explanatory note: Where tree roots from a tree on private property are found to be preventing access or causing damage to the water supply system, the Council will, where possible, prune the roots in such a way that the health or stability of the tree is not compromised.

10. Continuity of supply

The Council does not guarantee a constant flow of water or any maximum or minimum pressure.
Nothing in this bylaw should be construed as obliging the Council to provide or continue to provide a supply of water to any property. No allowance or compensation will be made or allowed by the Council if the water supply is restricted or interrupted, or if there is any change of pressure in the supply.
If a customer has a particular requirement for an uninterrupted flow, pressure or quality of water supply, it is the responsibility of that customer to provide any necessary storage, back up facilities or equipment necessary to meet that level of service.

Explanatory note: The Council as water supplier has certain obligations under the Water Services Act 2021 for the supply of drinking water. For example, the Council must ensure that a “sufficient quantity” of drinking water is provided to each point of supply except for necessary interruptions e.g. due to an emergency or during planned work on the water supply system or related infrastructure. Planned interruptions to supply may exceed eight hours if the Council gets the approval of Taumata Arowai and takes all practicable steps to inform affected customers.

11. Point of supply and supply pipes

There will only be one point of supply for each property, except where specifically approved (e.g. for a fire protection system).
A supply pipe must serve only one property and the customer must not extend the supply pipe, by hose or any other pipe, to any other property.
The Council will own and maintain any pipe up to the point of supply and the connection box, including the service valve, meter (where fitted), any restrictor (where fitted) isolation valve, and unions either side of the meter.
Water mains installed in residential private property (or residential right of way), fitted with one or more fire hydrants and for the benefit of more than one landowner, are maintained by the Council, up to and including, the hydrant(s).
Any pipe installed within an easement, and utilised by the person with the benefit of the easement or the landowner is owned and maintained by the named parties at their expense. Water mains protected by an easement in favour of the Council are owned and maintained by the Council.
While the customer may access and use the service valve to isolate the supply to the customer’s property, the Council does not guarantee the serviceability of the service valve.
Where the connection box is located on private property, the customer must maintain the area in and around the connection box by keeping it free of vegetation, or other matter or any obstruction which prevents, or is likely to prevent convenient access. Where the customer fails to keep access to the connection box free of growth or other obstructions, the Council may carry out any work necessary to remove any obstruction and may charge the customer for the cost of such work.
The customer will own and maintain the service pipe where it is located on private property and the supply pipe and any fittings on the customer’s side of the point of supply (e.g. backflow prevention device).
Where in the opinion of the Council, any pipe or fitting on the customer’s side of the point of supply has been damaged or is of inferior quality or workmanship, or is causing or is likely to cause water to be wasted or is insufficient for the proper supply of water, the Council may give the customer notice in writing requiring any work specified in the notice to be carried out in within the timeframe specified in the notice.
Where the customer fails to carry out any required work within the time period specified in the notice under subclause (9), in addition to any other remedies, the Council may charge the customer for the excess supply of water.

12. Firefighting supplies and fire protection systems

A fire protection system must be constructed, installed and operated so that water cannot be drawn from it for any purpose other than fire protection, and must be independent of any other water connection or supply on the property.
Where, in the opinion of the Council, an existing fire connection is constructed or located so water is, or is likely to be drawn from it or from any part of it by any person for purposes other than firefighting, the Council will require a meter to be installed on the fire connection.
The Council will not charge for water used for the purpose of extinguishing fires.
No person may install or connect a fire hose reel to a fire connection. A fire hose reel must be connected to a mains water supply.

Explanatory note: The water supplied to fire protection systems is from a fire connection, which can only be used for fire protection (for example, a fire protection sprinkler system). Fire hose reels must be connected to the mains water supply, as a fire hose can be used at any time and may be used for purposes other than fire protection.
Where a private water supply pipe is connected to a fire hydrant and the supply is not a dedicated firefighting supply, the Council may require that:
1. the connection supplying the fire hydrant is converted into a dedicated firefighting supply; and
2. all other water on the site is supplied by a separate new point of supply; and
3. if required, the property owner(s) apply for a new water connection for the new point of supply; and
4. all works and applications are paid for by the property owner(s).

13. Liability

The Council is not liable for any damage to any private plumbing system or for any loss or inconvenience to any customer as a result of being connected to the water supply.

14. Water supply no longer required due to demolition, removal or abandonment of buildings

When any property supplied with water by the Council no longer requires a supply of water (for example, due to the removal, demolition or abandonment of buildings), the customer must give notice in writing to the Council within one month of the date from which the water supply is no longer required, and apply to disconnect the water supply under clause 5, if applicable.

Explanatory note: Clause 14(1) does not apply if the property is being renovated, repaired, or redeveloped immediately following demolition or removal of buildings.
Where the customer fails to contact the Council as required by subclause (1), the Council may disconnect the water supply to a property where the removal, demolition or abandonment of buildings has occurred, and where the water supply connection:
1. has not been used for a period of 12 months or
2. is left in a condition that could be detrimental to the water supply system
If reconnection is required after such a disconnection, an application must be made in accordance with clause 5

15. Council may impose water restrictions

The Chief Executive may restrict or prohibit the use of water supplied to premises in the district where the Council’s ability to maintain an adequate supply of drinking water is, or may be, at risk due to:
1. drought
2. emergency
3. maintenance
4. excessive demand or
5. any other reason
Any restriction under subclause (1) may:
1. specify types of use that are restricted (e.g. limiting outdoor water use)
2. apply to the entire district or one or more parts of the district and
3. apply for any specified length of time
  
  Explanatory note: Types of restrictions may include (but are not limited to): volume restrictions per property, hand-held garden watering only, restrictions on the time of day, or day of garden watering (e.g. only after sunset or on specific days).
The Council will give notice of any restriction in any manner the Chief Executive considers is appropriate and reasonable in the circumstances of the restriction.
No person may use any water, or allow any water to be used in contravention of any restriction or prohibition made under this clause.

16. Water efficiency and prevention of waste

Explanatory note: The Council can restrict the water supply for any of the reasons set out in section 193 of the Local Government Act 2002, including for any breach of this bylaw. This includes failure to remedy a water leak. Any restricted supply must still provide a sufficient quantity of drinking water in accordance with section 25 of the Water Services Act 2021.

Unless specifically approved by the Council, the customer must not use water for:
1. a single pass heating or cooling system
2. the dilution of trade waste prior to disposal or
3. driving lifts, generators, condensers, machinery, or other similar devices
The customer must have water conservation equipment as part of any system using water from a Council water supply for heating or cooling purposes (e.g. air conditioning, industrial plant) so that the consumption is limited to that required to make up reasonable losses due to evaporation, wind, flushing, and similar effects.

Explanatory note: Discharge of cooling water must comply with part 2 of this Bylaw and with the Council’s Stormwater and Land Drainage Bylaw.
A customer must not waste water, or allow water to be wasted, from any pipe, tap, or other fitting on their property.

Explanatory note: Wasting water is an offence under sections 192 and 224 of the Local Government Act 2002 and may result in disconnection or restriction of the supply and/or prosecution. Examples of water being wasted include (but are not limited to): watering in areas where it is not required (e.g. driveways), excessive watering (including water flowing off the customer’s property i.e. to the footpath, road or a neighbouring property or causing flooding), and unrepaired leaks.

Excessive water use will also be charged in accordance with the excess water supply targeted rates from 1 July 2022.

17. Supplementary water storage for Banks Peninsula water supply areas

For all new residential or commercial properties constructed within the Council water supply areas of Akaroa (including Takamatua), Duvauchelle, Wainui, Pigeon Bay, Little River and Birdlings Flat, and where connection to the Council water supply is sought; the customer must install a tank or facility with a minimum capacity of 5,000 litres for the purpose of collecting and storing rainwater for non-potable usage.

Explanatory note: Examples of non-potable water use include toilet flushing and watering the garden.
For the purposes of subclause (1), the construction of new properties means:
1. the construction of a residential or commercial building on an undeveloped site or
2. the construction of a replacement residential or commercial building that increases the footprint area of the pre-existing building on the site;
3. but does not include:
  1. the construction of a replacement building that has a footprint area that is the same or less than the pre-existing building;
  2. repairs or alterations to any existing building;
  3. the construction of a garage or outbuilding; or
  4. the construction of a temporary building that has an intended life of less than five years.
    
    Explanatory note: This bylaw requires supplementary water storage for non-potable purposes in Banks Peninsula, but there are additional requirements for water storage tanks for other purposes and in other areas of the Christchurch district.
Where multiple tanks are required on a property for different purposes, the Council may give permission for a single tank to meet multiple requirements.

Explanatory note: Tanks may be required for the purposes of stormwater detention, fire-fighting, or other non-potable purposes. Tanks must meet all other regulatory requirements, including backflow prevention in order for the Council to consider granting approval.

Additionally, if any person believes that compliance with the requirement in clause 17 would adversely affect them or their business, without a corresponding public benefit, they can apply to the Council for a dispensation from compliance with this requirement under clause 13 of the General Bylaw 2008.

18. Backflow prevention

At the Council’s request, the customer must provide any information about any use or activity at their property in relation to backflow risks, and take any action requested by the Council to ensure backflow prevention is achieved to the Council’s satisfaction.
Where there is a change of use or activity carried out at their property that may alter the hazard rating or the risk of backflow occurring, the customer must:
1. notify the Council of any change of use or activity and
2. demonstrate how backflow prevention will be achieved in relation to the change, to the Council’s satisfaction and
3. install a backflow prevention device if one is required, or comply with any requirement made by Council under section 27 of the Water Services Act 2021
A backflow prevention device must not be bypassed unless the bypass is also fitted with a backflow prevention device appropriate for the same hazard rating and approved by the Council.
The Council may charge for site audits and applications for changes in hazard rating, and may recover costs for installing, testing and maintaining backflow prevention devices.

Explanatory note: Backflow is a risk of contamination of our public water supply. Backflow prevention measures are intended to protect the quality and safety of our drinking water.

Property owners are required to install the appropriate level of backflow prevention in relation to the backflow risks arising from activities on their site. This may be either by ensuring an adequate air gap or by installing a Council-approved backflow prevention device.

It is the customer’s responsibility under legislation such as the Building Act 2004 to take all necessary measures on the customer’s side of the point of supply to prevent water which has been drawn from the Council water supply from returning to that supply (i.e. backflow prevention measures).

To change the hazard rating, the property owner can request the Council review the hazard rating on their property. The property owner must pay any relevant fee for inspection as outlined in the Council’s Schedule of Fees and Charges. Alternatively, the customer may provide the Council with a report from a suitably qualified person advising of the risk category for the property.

Where a customer cannot demonstrate that the risk of backflow is adequately managed, in accordance with section 27 of the Water Services Act 2021, the Council may fit a backflow prevention device on the public side of the point of supply, and recover the costs from the property owner for the design, installation, maintenance and testing of the device.

More information on the requirements for backflow prevention can be found on the Council’s website – www.ccc.govt.nz.

19. Installation of meters

For any property there shall be only one metered supply, unless otherwise approved by the Council.
All new connections for fire protection systems must have a meter of a type that has minimal pressure loss characteristics as specified by the Council.
All meters (other than secondary meters referred to in subclause(6)) are supplied, installed and maintained by the Council, and remain the property of the Council.
All Council-owned water meters are to be located on Council property unless prior written approval is given otherwise.
If a meter becomes difficult to access due to changes made by the customer, the Council may relocate it to a more accessible location and recover the costs of relocation from the customer.
Where one or more secondary meters are fitted, whether as a result of a requirement of the Council or at the request of the customer(s), all such meters are the property of the customer(s) who must pay for all costs relating to these secondary meters including for the installation, maintenance, monitoring and reading of the meters.

Explanatory note: It is the Council’s policy to install water meters on all supplies for the purposes of monitoring water consumption and detecting leaks, and for volumetric charging where applicable.

20. Meters on private property

Where meters are to be installed on a property the customer must:
1. provide a Council approved location within the property for the meter;
2. take sufficient precautions to protect the meter from damage at all times;
3. enclose the meter in a suitable box or other enclosure and, in cases where natural support is absent, provide suitable wall brackets or other support; and
4. ensure that the meter is readily accessible for reading and servicing at all times.

21. Reading of meters and accounts

Meters will be read, and where applicable, accounts rendered, at such intervals as the Chief Executive may determine.
Meter readings made at the request of the customer will be charged for as set out in the Council’s schedule of fees and charges.
The customer must pay all charges for the supply of water as determined by the Council.
A customer must give the Council five working days’ notice to arrange a final water meter reading and pay any relevant fee for the final reading as set out in the Council’s schedule of fees and charges.

22. Estimated accounts

If any meter ceases to register, is difficult to access or is unable to be read, the Council will estimate the consumption based on the average of the previous available consumption periods for that customer.
If the previous available consumption periods for that customer contain large variations for seasonal or other reasons, the Council will determine a reasonable estimate based on the available information.
Where a restrictor is damaged, without prejudice to other remedies available, the Council may assess and recover the value of water drawn over and above what would have been supplied if the restrictor was in working order.
The Council’s decision under this clause is final, and the customer must pay the estimated account.

23. Testing of meters

If a customer disputes the accuracy of a meter, the customer may request that the Council have it tested. The customer must pay the cost of having the meter tested.
If any tested meter is found to be reading inaccurately, the Council will adjust the customer’s account accordingly, and either refund or charge the customer according to the adjusted account.

24. Works must comply

Any person responsible for the construction of infrastructure which is to be vested in Council and become part of the water supply system, must comply with all relevant codes of practice, standards, specifications, approvals and conditions relating to such infrastructure.
Any person responsible for the construction or maintenance of infrastructure which is to connect to the water supply system must comply with all relevant codes of practice, standards, specifications, approvals and conditions relating to the connection.
The Council is not required to accept the vesting of infrastructure, or a connection to the system which does not comply with subclauses (1)and (2).

25. Identify underground services prior to site works

Any person undertaking site works must view and verify the as-built plans held by the Council prior to the commencement of works to establish whether or not Council services are located in the vicinity of the proposed work.
If any pipe, drain or other asset is found not to be on as-built plans, or incorrectly shown on the as-built plans, the person must determine what the pipe, drain or other asset is, and supply that information to the Council.

Explanatory note: Any works to be undertaken within the road corridor (which includes the road, footpath and berm) is regulated under the Utilities Access Act 2010 and the Council‘s Traffic and Parking Bylaw, and requires the submission of a Corridor Access Request to the Council.

Part 2: Wastewater

26. Objectives

The objectives of this part of the bylaw are to:
1. regulate the use of land, structures and infrastructure associated with the wastewater system to protect these assets from damage, misuse or loss
2. prevent unauthorised access and interference with a connection to the wastewater system
3. protect the wastewater system from stormwater inflow and groundwater infiltration and
4. define the obligations of the Council, installers, owners and the public in matters related to the wastewater system

Explanatory note: Objectives, policies and standards relevant to this part of the bylaw can be found in the Council’s Te Wai Ora o Tāne Integrated Water Strategy, the Infrastructure Design Standards and in the resource consents that the Council holds for the public wastewater system. The bylaw is part of how the Council can give effect to Te Mana o te Wai.

27. Approval required for connection, discharge and disconnection

No person may, without the Council’s written approval
1. connect, or allow the connection of any fittings, to the wastewater system
2. disconnect from the wastewater system
3. change the location of the point of discharge
4. increase the number of residential units connected to an existing connection or
5. increase the commercial discharge (flow or volume) through an existing connection
  
  Explanatory note: Written approval may be under this bylaw, or under the Trade Waste Bylaw, where relevant.
A written application for approval of any matter in subclause (1) must be made in the form required, must contain all information requested, and must be accompanied by the relevant fee (if any).
An authorised officer considering an application may require the applicant to provide further information, at the applicant’s cost, in order to process an approval.
The Council may impose conditions as part of an approval. Any conditions must be complied with in the exercise of the approval.
Without limitation, the Council may decline approval to connect to the wastewater system where, in the Council’s reasonable opinion:
1. connection would or may give rise to wastewater overflows
2. there is insufficient capacity in the system to accommodate the connection
3. the connection could compromise the Council’s ability to maintain levels of service
4. the connection is outside the area currently served by the wastewater system, regardless of its proximity to any specific component of the wastewater system or
5. refusal is necessary to protect the wastewater system, the health and safety of any person, or the environment
Where the Council declines an application it will notify the applicant of the decision, giving reasons
The Council may, at any time, review a connection approval and any conditions.
Following the review, the Council may, after obtaining and considering the written views of the customer.
1. vary or add any conditions that the Council considers necessary or
2. require a new application for connection to be submitted within the timeframe specified

28. Restrictions on access to the wastewater system

No person may, without the Council’s approval, carry out any of the following restricted activities:
1. enter any fenced area, building, or facility that is part of the wastewater system
2. access, tamper with, or otherwise interfere with any part of the wastewater system
3. make any connection to or discharge into, any part of the wastewater system or
4. remove, cover, or otherwise interfere with any manhole cover, inlet or other equipment associated with the wastewater system

29. Restricted activities within Maintenance Access Corridors

This clause applies to parts of the wastewater system that are located underground and within non-Council land. The Council requires that these parts of the wastewater system are accessible in order to repair, replace, or otherwise maintain these parts of the wastewater system.
This clause does not apply where there is an easement in favour of the Council registered against a Record of Title for a property that enables adequate maintenance access for the wastewater system, irrespective of the width of the easement strip created by that easement.
No person may, without the Council’s written approval under this bylaw, carry out the following restricted activities
1. build, place or install, or allow to be built, placed or installed, any building or structure (other than a boundary fence), over or within a Maintenance Access Corridor
2. lay or permit any utility service or private pipe across or along the line of an existing part of the wastewater system within a Maintenance Access Corridor or
3. undertake site works within a Maintenance Access Corridor
  
  Explanatory note: Structures include temporary or relocatable buildings (such as sheds), shipping containers, storage tanks, decks, hard landscaping, etc. Each request will be considered on a case-by-case basis, taking into account the particular set of circumstances involved, and the likely access needs for maintenance. Reinstatement of areas after access for maintenance will be completed to a safe standard, and may not be to the exact prior condition (eg: it may not be possible to reinstate or match some features or finishes, such as coloured or textured concrete).
  
  Written approval for a similar purpose provided under a revoked version of this bylaw is considered written approval under this bylaw, in accordance with the savings provisions in this bylaw (clause 41).
  
  If any person believes that compliance with the requirement in clause 29 would adversely affect them or their business, without a corresponding public benefit, they can apply to the Council for a dispensation from compliance with this requirement under clause 13 of the General Bylaw 2008.
No person may plant any tree within a Maintenance Access Corridor that is likely to cause a nuisance or damage to any part of the wastewater system.
Where the Council’s infrastructure or asset is a pipe, the Maintenance Access Corridor width is calculated by the Council as the greater of either:
1. twice the buried depth of the pipe (surface to trench base), plus the outside diameter of the pipe or
2. 1.5 metres from either side of the centre of the pipe
Where the infrastructure or asset is not a pipe, the Maintenance Access Corridor is one metre from the asset’s border in all directions (eg a manhole).

30. Applications and approvals for restricted activities within a maintenance access corridor

A written application for approval of a restricted activity within a Maintenance Access Corridor must be made in the form required, must contain all information requested, and must be accompanied by the relevant fee (if any).
An authorised officer considering an application may require the applicant to provide further information, at the applicant’s cost, in order to process an approval.
The Council may impose conditions as part of an approval. Any conditions must be complied with in the exercise of the approval.
Where the Council declines an application it will notify the applicant of the decision, giving reasons.

31. Discharges into the wastewater system

No person may cause or allow any of the following to enter a wastewater pipe or fitting, a drain connected with a wastewater pipe, or the wastewater system, without the Council’s written approval under clause 27, or an approval or consent under the Council’s Trade Waste Bylaw:
1. stormwater or groundwater (including from a water pipe, an artesian well or spring, surface water, subsoil drainage or roof water)
2. water from any hydraulic appliance, or de-watering or construction process
3. condensing or cooling water
4. fat, oil, food waste, sediment or other extraneous matter from a non-residential property where food is prepared, processed or served
5. food waste other than domestic household food waste from a waste disposal unit or
6. any steam, or any other matter (solid or liquid), at a temperature higher than 40°C
No person may cause or allow any prohibited waste to enter any plumbing fixture or drain connected with a wastewater pipe, or the wastewater system.

Explanatory note: The wastewater system takes away the wastewater from toilets, and from basins, showers, baths, washing machines, sinks and dishwashers. The system is designed to handle wastewater produced during normal daily activities. This may contain soaps, household cleaners, detergents, cooking by-products, toilet paper and bodily fluids. To avoid blockages and damage to private pipes and the public wastewater system, do not dispose of substances or things down sinks, drains or toilets that the system is not designed to handle.

Things that must not be disposed of down a toilet or sink are: wipes (wet wipes, baby wipes or any kind of “flushable” wipes), nappies, sanitary products or condoms; gravel-like substances, such as cat litter or fish tank gravel; hazardous substances, such as fuel or poisons (other than household cleaning products); fat or cooking oil (other than from washing dishes); clothing; or plastic. Many things people have attempted to inappropriately dispose of down their toilet or sink have blocked their own pipes, caused a blockage in the wastewater system, or damaged the equipment used to treat our wastewater.
Customers with a pressure wastewater system, or any other system that is connected to the public wastewater system, must use that system in accordance with any operating manual or guidelines for that system.

Explanatory note: The guidelines for pressure systems owned and/or installed by, or required by the Council are available on the Council’s website under ‘Wastewater’.
Where a blockage in the public wastewater system is caused by prohibited waste generated from within a private property, the Council will recover the costs of repairs to the network from the property owner.

32. Maintenance of private wastewater drains

The customer owns the private wastewater drains within the customer’s property and on the customer’s side of the point of discharge, and is responsible for all repairs and associated costs.

Explanatory note: The Council owns and is responsible for maintenance of the public wastewater system including the pipe and the fittings from the point of discharge.
Private wastewater drains must be maintained in a state which is free from cracks and other defects which may allow infiltration, leakage, or cause blockages.
If the Council believes that wastewater drains on private property are deficient, damaged, blocked, receiving excessive inflow and infiltration, are leaking, or are otherwise not in a satisfactory operating state; the Council may require the property owner to investigate the drain and rectify any issues, at the owner’s cost.

Explanatory note: Wastewater leaching from substandard drains can cause public health or environmental health issues (such as contaminating groundwater, producing a foul odour or attracting flies). Stormwater, groundwater, tree roots, sediment and other contaminants can enter the public wastewater system from cracks and damage in private wastewater drains, and overload or block the public wastewater system, or cause damage to the system or its machinery.
Where the Council requires a property owner to investigate and rectify any issues, a property owner must:
1. Engage a suitably qualified person to undertake a camera investigation (or other agreed method of investigation) of the drain, and prepare a report on the findings; and
2. Submit the report to the Council on the condition of the drains, prepared by a registered drainlayer, that includes either an appropriate repair strategy, or confirmation that the drain is in a satisfactory operating state (ie: contains no cracks, substandard joins, tree roots or other signs of blockage); and
3. If repairs or replacements are necessary to fulfil the repair strategy, the property owner must demonstrate, to the Council’s satisfaction that the repairs or replacements have occurred.
Where the Council requires a property owner to investigate and rectify a drain under subclauses (3) and (4), the investigation and any repairs or replacements must be completed within timeframes as specified or agreed by the Council.

Explanatory note: The requirements of this bylaw do not limit the Council from taking action under section 459 of the Local Government Act 1974.

33. Protection from damage caused by trees

No person may plant any tree in a position that is likely to cause a nuisance or damage to any part of the wastewater system, or allow any tree or its roots to cause a nuisance or damage to any part of the wastewater system.

Explanatory note: Where the roots of any tree on private property are causing damage, interference or blockage of any part of the wastewater system, or otherwise restricting access to any part of the network, the Council may take action to remove the tree, or to trim the roots of the tree, under sections 355 or 468 of the Local Government Act 1974, as appropriate. Where tree roots from a tree located on private property are found to be preventing access or causing damage to the wastewater network, the Council will, where possible, prune the roots in such a way that the health and stability of the tree are not compromised.

34. Works must comply

Any person responsible for the construction of infrastructure which is to be vested in Council and become part of the wastewater system, must comply with all relevant codes of practice, standards, specifications, approvals and conditions relating to such infrastructure.
Any person responsible for the construction or maintenance of infrastructure which is to connect to the wastewater system must comply with all relevant codes of practice, standards, specifications, approvals and conditions relating to the connection.
The Council is not required to accept the vesting of infrastructure, or a connection to the system which does not comply with subclauses (1) and (2).

35. Identify underground services prior to site works

Any person undertaking site works must view and verify the as-built plans held by the Council prior to the commencement of works to establish whether or not Council services are located in the vicinity of the proposed work.
If any pipe, drain or other asset is found not to be on as-built plans, or incorrectly shown on the as-built plans, the person must determine what the pipe, drain or other asset is, and supply that information to the Council.

Explanatory note: Any works to be undertaken within the road corridor (which includes the road, footpath and berm) is regulated under the Utilities Access Act 2010 and requires the submission of a Corridor Access Request to the Council.

Part 3: General and administrative

36. Monitoring and inspections

The Council may carry out monitoring and inspections of any property for the purposes of determining compliance with approvals and this bylaw.
The occupier of any property must co-operate with any monitoring and inspections required at the discretion of an authorised officer, including, but not limited to:
1. enabling access to enter the property and
2. providing documents, plans and other information

Explanatory note: The Local Government Act 1974, the Local Government Act 2002, and the Christchurch District Drainage Act 1951 also contain various powers for entry and inspection of private property, and the Council may also rely on those powers from time to time.

37. Offence and penalty

Every person who breaches this bylaw commits an offence and is liable on conviction to a fine not exceeding $20,000, as set out in the Local Government Act 2002.

Explanatory note: There are also offences and penalties provided for in the Local Government Act 2002 and the Water Services Act 2021 (and other Acts) concerning water related issues, or damage to Council property. For example, see sections 175-176, 224-228, 232, and 242 of the Local Government Act 2002, and section173 of the Water Services Act 2021.

38. Recovery of costs

Where any breach of this bylaw causes damage to the water supply system or wastewater system, the Council may recover the cost of repairing the damage and any associated losses or expenses incurred by the Council from the person responsible for the breach.

Explanatory note: Under section 175 of the Local Government Act 2002, the Council has a right to recover against any person who wilfully or negligently damages Council property.

39. Fees

Where this bylaw provides for the Council to issue an approval, or give any authority for any thing (for example, a change in hazard rating), or carry out an inspection, monitoring, review or audit, the Council may require the payment of a fee.
Where this bylaw provides for a connection to the water supply system or the wastewater system, or the provision of any good, service, or amenity the Council may require payment of a fee for that service.

Explanatory note: Any fees are set out in the Council’s Annual Plan or Long Term Plan.

The Council also charges targeted rates in relation to water supply and wastewater. The rates charged and how they are calculated is set out in the Funding Impact Statement of either the Council’s Annual Plan or Long Term Plan, as applicable for the particular year. The purpose of these rates is to recover the operating costs of providing the water supply and wastewater systems, plus a significant share of the expected cost of asset renewal and replacement.

The Council can restrict the water supply for non-payment of any water-related charges. Any restricted supply must still provide a sufficient quantity of drinking water in accordance with section 25 of the Water Services Act 2021.

40. Christchurch City Council General Bylaw 2008

The provisions of the Christchurch City Council General Bylaw 2008 and any bylaw passed in amendment or substitution are implied into, and form part of this bylaw.

41. Revocations and savings

The Christchurch City Council Water Supply, Wastewater and Stormwater Bylaw 2014 is revoked.
Any permission, consent, agreement, approval or any other act of authority which originated under the Christchurch City Council Water Supply, Wastewater and Stormwater Bylaw 2014, or which was continued by that bylaw and which is still in force at the commencement of this bylaw continues to have full force and effect for the purpose of this bylaw.
This bylaw is implied into and forms part of any permission, consent, agreement, approval, or any other act of authority continued by this clause.
The revocation of the Christchurch City Council Water Supply, Wastewater and Stormwater Bylaw 2014 does not prevent any legal proceedings, criminal or civil, being taken to enforce that bylaw and such proceedings continue to be dealt with and completed as if that bylaw had not been revoked.

The initial resolution to make this bylaw was passed by a Committee of Council on 10 November 2021, and was confirmed, following consideration of submissions received during a special consultative procedure, at a subsequent meeting of the Council on 9 June 2022.
