Kaiteriteri projects

Update May 2026

Improvements to the Kaiteriteri Water Treatment Plant will help keep the community’s water safe and reliable.

Drinking water for the area comes from two bores on River Road in Riwaka.

The current project builds on an upgrade done in 2018 when UV treatment was added as a protozoa barrier. This upgrade adds to the multi-barrier treatment approach by including additional filtration units, extra pumps and pump housing, and new chlorination systems.

While the plant was originally designed to use chlorination on a temporary, seasonal basis, a decision has since been made to treat all water supplies year-round. To support this, specialist equipment has been installed in response to updated regulations by the water regulator – Taumata Arowai – requiring residual disinfection.

The project has also been designed to deal with occasional water clarity issues. At times, naturally occurring materials in the bore it draws from can cause brief increases in cloudiness. By installing cartridge filters, these particles can be captured before the water reaches the treatment process, improving overall water quality.

In addition, a new automated flush-to-waste system will allow any cloudy water to be safely diverted to the stormwater system in a soak pit instead of flushing water away from the site with hoses into roadside drains.

These upgrades are expected to be completed later this year and will ensure the Kaiteriteri Water Treatment Plant continues to serve the community effectively, now and into the future.

The project is to improve the flush to waste line, filtration and contact tank for the Kaiteriteri Water Treatment Plant. Part of this is to provide extra pumps to suit network pressure requirements and support needs in the community.
