Supplied Residents in areas affected by the boil water notice were notified through Civil Defence's text alert system on Saturday. Residents in parts of Shirley, Bexley, Wainoni and New Brighton were advised to boil their water after traces of E coli were found in the water supply. Christchurch City Council reticulation and maintenance manager Tim Drennan said the boil water notice would remain in place until laboratory tests confirmed the water was safe to drink. If you cannot boil water, treat it by adding one teaspoon of household bleach per 10 litres of water and leave for 30 minutes." A council spokeswoman said three days of clear counts had to be recorded before the boil water notice could be lifted.
