Temporary halt to chlorination

Kawerau District Council has put a temporary halt to chlorinating the town water supply from today, while it looks for a way to resolve issues with water discolouration.

Since chlorination began in July last year, there has been sporadic yellow to brown discolouration of the town’s tap water.

Although safe to drink, chlorine in the water pipes has caused staining from natural manganese in the water and dislodged bacterial material which has built up in the system over many years.

To resolve the discolouration issue, Council will flush the whole reticulation network and trial cleaning the pipes by air scouring.

Once solved Council will revisit chlorinating the water supply to meet the drinking water standards.
