Temporary water chlorination: Richmond and Kaiteriteri

Monday 18 June 2018

Short-term chlorination of the Richmond and Kaiteriteri water supplies is planned to ensure a safe water supply while water infrastructure work is carried out over the next few months.


A  large stormwater pipeline is due to be installed in the Lower Queen Street area, and will require two large water mains to be lowered to allow the stormwater pipe to cross them. Short-term chlorination of the water supply in Richmond  will occur to ensure that the water remains safe to drink during these alterations. Work is currently planned to occur in mid-June and again in August.

The concentration of chlorine will be low - about a third of the dose used during the most recent temporary chlorination.


We are building a water treatment plant in Riwaka, and in July the plant will be commissioned and begin supplying treated water to Kaiteriteri. During the commissioning phase, the emergency chlorination system will be turned on to make sure it works. The chlorination will probably occur for no more than a week.
