Our waterways are precious community resources that we need to protect for future generations.
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.
In the 2017/18 year, all Christchurch water supplies failed to meet the drinking-water quality standards specifically for protozoa.
Water supplies for 74% of the Christchurch population failed to comply with the Health Act requirements for safe drinking water supplies.
This resulted in the Council chlorinating the city’s water supply until work on fixing the wellheads is completed, which is expected to be done by the end of 2019
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% of sites were recorded as having poor water quality, 40% had fair water quality and 19% had good water quality. 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.
