Christchurch City Council will consider a report on 25 January 2018 which recommends it treat the city’s water supply with chlorine until work has been completed on upgrading the below ground well heads.
The report has been prepared by Council staff and will be considered by Mayor Lianne Dalziel and Councillors in public during the 25 January Council meeting.
The meeting starts at 9.30am. It is expected the report on the water issues will be considered about 10am.
Read the report on Christchurch's water supply.
The Council meeting will be recorded and livestreamed online.
The report has been prompted by concern that some of the city’s below ground wells are not sufficiently sealed to eliminate the risk of contamination.
Water chlorination is the process of adding chlorine to the water supply to keep it safe from harmful bacteria. Sodium Hypochlorite is used in Christchurch. It can be added as a precaution after routine work, such as reservoir cleaning, or as a result of finding bacteria in the water supply during routine water sampling.
Chlorine may be noticed by its distinctive smell or taste, but in most cases these effects are diluted relatively quickly as the chlorinated water is mixed with fresh unchlorinated water.
The Christchurch water supply is made up of several zones that operate independently of each other.
Please note that the water supplies for Akaroa, Duvauchelle, Little River and Takamatua are permanently chlorinated.
