Water chlorination update – treatment in Papanui will start on 6 April

Here’s a Christchurch water chlorination update from the Papanui Innes Community Board. Treatment in the Northwest zone will begin this Friday 6 April. This zone includes the top part of the Papanui Ward, including the pump stations in Prestons Road and Grampian Street (a map of the zone is available via the linked article). All Council water supplies are expected to be chlorinated by the end of this month.

An update on chlorination:

There has been a change in sequencing of the rollout of temporary chlorination and CCC will now start treatment in the Northwest zone from Friday 6 April.

Treatment in the Riccarton zone will start on Wednesday 4 April, and in Sockburn and Hornby (the West zone) on Friday 6 April.

Previously CCC had planned to start treatment in the two biggest zones, Central and Northwest, at the end of April.

Amending the timeframe will reduce the overall demand on staff at the end of the programme and allow for a more efficient roll out.

Valves between the central and northwest zone have been shut off to stop any transfer of chlorinated water into the central zone. The central zone also has a higher pressure than the northwest, which would prevent water from the northwest flowing into the central area.
