The Council will begin the temporary treatment of the city's water supply in the Brooklands, Kainga and Spencerville area on Monday.

Final preparations are under way to begin the treatment. 

Following Brooklands/Kainga, which includes Spencerville, temporary treatment will be introduced gradually across the city, including Riccarton, Halswell, Parklands, the Heathcote Valley and Lyttelton Harbour.

The two largest zones, northwest and central, will be last to be treated.

The northwest zone stretches from Belfast through to Yaldhurst and includes parts of Riccarton and Addington and supplies 80,000 people.  The central zone supplies 255,000 people from Spreydon and Cashmere as well as in Papanui and Grassmere and across to Linwood, Aranui and New Brighton.

It is expected that chlorination will be set up at all Council supplies in Christchurch city and Banks Peninsula by the end of April.

There is a map on our website showing areas of the city where chlorine is being used and this will be updated as we progress. 

The Council website has more information about temporary chlorination.
