Our waterways are precious community resources that we need to protect for future generations.

What this means

We would like the community to be more involved in water conservation and quality programmes, so we can better protect the quantity and quality of our water.

How we will get there

Work closely with river care groups to raise community awareness of improving waterways and sustainable water use.

Establish an urban waterways research programme with the Waterways Centre for Freshwater Management.

Complete the Integrated Water Strategy.

Improve environmental outcomes through implementation of stormwater management plans.

Council to work with architects, developers and builders to optimise stormwater treatment and discharge and incorporate innovative outcomes.

Further advocacy work to Government  and community on copper free brake pads.

Secure status of water supply at most pump stations. 

How we are doing 

Christchurch's water supplies meet bacteriological and protozoal standardsMixed Results

Christchurch's water supplies have consistently met New Zealand drinking water standards for microbiological compliance with 100 percent of the water supplied to residents coming from complying zones since 2015.

Protozoan compliance since the earthquakes show that at least 75 percent of water supplied to the population of the City complying with the drinking water standards.  This proportion has declined slightly since 2012. 

Quality of Christchurch waterwaysMixed Results


Since 2013 fewer sites are rated as poor and more have moved to the fair category of the Council's water quality index

In 2017, 40%, 40% and 19% of sites were recorded as having ‘poor’, ‘fair’ and ‘good’ water quality, respectively. No site had ‘very good’ water quality, as guidelines were exceeded on at least one occasion at all sites. There was also no site that recorded ‘very poor’ water quality.

The Ōpāwaho/ Heathcote River and Linwood Canal catchments generally had ‘poor’ water quality. All other catchments generally had ‘fair’ to ‘good’ water quality.

The Ōtūkaikino River recorded the best water quality out of all the catchments and the Ōpāwaho/Heathcote River catchment recorded the worst water quality, with the 11 worst sites all being from this catchment.
