We are building a new wastewater system for Akaroa. The new treatment plant will be next to the water supply reservoir on Old Coach Road. It will use modern techniques to treat Akaroa’s wastewater.
The new wastewater treatment plant will replace the existing plant at Takapūneke Reserve and the outfall discharging to Akaroa Harbour.
All wastewater leaving the new plant will be treated to ensure it is safe to reuse to irrigate parks and flush public toilets in Akaroa and to irrigate new areas of native trees and plants at Robinsons Bay, Hammond Point and Takamātua.
We are establishing a community reference group for this project.
Group members will help the project team in the lead-up to our irrigation consent application. This will ensure local voices are heard and community concerns are understood and, where possible, addressed.
The group will comprise an independent facilitator, a member of Te Pātaka o Rākaihautū Banks Peninsula Community Board, two representatives of Ōnuku Rūnanga and up to five people from the local community. They will work with members of the Council’s project team.
Their role will be to advise the project team of community concerns and to share ideas to enable the project to be as beneficial as possible to the community. This may be through opportunities for improvements around recreation, heritage, education, ecology, landscape and the like.
The group will help us as we develop the following areas:
If you’re interested in being involved, please email Senior Project Manager Kylie Hills at email@example.com and put 'Community Reference Group' in the subject line. Please include information about:
We suggest you read the draft terms of reference [DOCX, 319 KB] before you apply.
The group is likely to meet four to six times between August and November 2021. Meetings will be on week-day evenings in Akaroa.
Please ensure we receive your email by 10am Monday 2 August 2021.
The group’s membership will be finalised at the August meeting of Te Pātaka o Rākaihautū Banks Peninsula Community Board.
A $3.2 million project is underway in Akaroa to reduce the inflow and infiltration of groundwater and stormwater into the wastewater network.
This is water that enters the system through leaky pipes, gutter downpipes and household gully traps that receive surface water.
Our goal is to reduce the volume of groundwater and stormwater flowing into the wastewater network. Having less of this unwanted water in the system will reduce raw sewage overflows to the harbour in wet weather. It will also reduce the storage capacity needed to hold treated wastewater during periods of wet weather when we are unable to irrigate.
As part of this work, we have taken a closer look at how wastewater from our water supply treatment plant at L’aube Hill contributes to the overall volume of wastewater in the network.
This is water being sent to the wastewater network from the water supply treatment plant when it flushes and cleans its filter systems. We have identified opportunities to improve efficiency at the plant, which we expect will reduce this flow. Historically, this water has contributed to the volume of excess water in the wastewater network.
While our focus is on Council-owned parts of the network, we have also visited 119 properties in Akaroa to check for possible problems with private property connections. This has identified issues such as broken pipes in household connections, tree roots breaking into pipes and roof downpipes connected into the sewer network.
We’ll be contacting individual property owners to let them know what the issues are and outlining options to resolve them.
This is a great opportunity for the people of Akaroa to be a part of the solution, and to help reduce wastewater overflows into the harbour.
We expect to have addressed the biggest issues in the Council’s network by April 2022.
The new scheme is dispersed over four sites in the Inner Bays area.
The project team recently purchased a farm on Sawmill Road and is negotiating with landowners to buy the other land needed.
The following is the wording of the Council resolution supporting the Inner Bays Irrigation Scheme option, passed on 10 December 2020.
In response to question one of the Akaroa Treated Wastewater Options consultation document, 'should we discharge highly treated wastewater from our new treatment plant to land or should we continue to discharge into Akaroa Harbour?'
That the Council:
In response to question two of the Akaroa Treated Wastewater Options consultation document, 'if it decides to develop a scheme where highly treated wastewater is used on land for irrigation, where would you prefer the Council to irrigate? Inner Bays (Robinsons Bay, Hammond Point, Takamātua), Goughs Bay or Pompeys Pillar?'
That the Council:
That the Council:
In response to question four of the Akaroa Treated Wastewater Options consultation document, 'would you like use to explore the feasibility of a purple pipe scheme for Akaroa, so that residential property owners could use the water for garden watering and other nondrinking purposes?'
That the Council:
That the Council:
Moved: Councillor Templeton
Seconded: Councillor Coker
(Councillors Chu, Gough and MacDonald requested that their votes against the resolutions be recorded).
We have resource consents to build the new wastewater treatment plant on Old Coach Road, the new pump station at the Childrens Bay boat park and to upgrade the wastewater network of pipes and connections.
Other consents will be needed for the scheme, including consent to:
A critical part of this work is to complete an assessment of environmental effects for each consent required. We have appointed the engineering consultancy firm Stantec to work with us on this aspect of the project.
We expect to lodge our resource consent applications in the first half of 2022.
Our work on this project began in 2014. This section gives some background to the project.
We undertook five weeks of community consultation outlining four viable options in August 2020, before the hearings panel recommended and the Council accepted the Inner Bays Irrigation Scheme (Option 1).
We were granted consent to build a new wastewater treatment plant on Old Coach Road, a new pump station at the Childrens Bay boat park and to upgrade the wastewater network of pipes and connections.
However, our applications for consent to construct a new pipe outfall to Akaroa Harbour, and discharge treated wastewater via that pipe outfall, were declined. The hearing commissioners said a harbour discharge was offensive to Ngāi Tahu and that we had not adequately investigated alternatives.
We appealed this decision, but in 2019 we decided to drop the appeal.
The existing Akaroa wastewater treatment plant(external link) was built in the early 1960s at Takapūneke Historic Reserve.
It is now due for replacement and needs to be moved because the reserve is a historically and culturally sensitive place.
In 1830, Takapūneke was the site of a massacre. Te Rauparahau, with help from the captain of the British ship the brig Elizabeth, captured the rangitira (chief) of the māori pa, Te Miharanui, and killed about 200 of his people on the site.
It is now widely acknowledged that building a wastewater treatment plant at this site was extremely insensitive. The Council now recognises the area as a historic reserve and worked with Ōnuku Rūnanga in 2018 to develop the Takapūneke Reserve Management Plan(external link).
A site at the top of Old Coach Road was chosen for the new wastewater treatment plant in 2012.
This was one of two sites recommended by the Akaroa Community Wastewater Working Party and Akaroa/Wairewa Community Board. It was chosen for its proximity to Akaroa and to areas that in future could use treated wastewater for irrigation.
This site was supported by Ōnuku Rūnanga and is now owned by the Council.
