Christchurch's water supply will be chlorinated from March 26, starting with Brooklands, Kainga, Heathcote Valley123RF Chlorination of Christchurch's water supply will take place from March 26, with treatment taking place at the city’s 56 pumping stations. Christchurch's water supply will be chlorinated from March 26, starting with Brooklands, Kainga and Heathcote Valley. The first widespread treatment of Christchurch's drinking water since the 2011 earthquake, the chlorination programme will take about four weeks to be rolled out across the city, starting in the Brooklands, Kainga and Heathcote Valley areas. Chlorination is required only at water sources, so treatment is not needed throughout the entire supply network. "If you taste chlorine it means it's doing its job - it's reacted with organic matter."
