Tapanui Water Treatment Plant

Council reminds consumers that a boil water notice is in place for Tapanui. This is due to treatment difficulties at the plant.

Update 21 Feb 2025

Council has engaged an independent engineer to investigate the continued treatment difficulties experienced at the plant.

Given the age of the plant, the first step Council has identified is to inspect the filter at the plant and assess what state the filter is in and what is required to optimise its performance.

This requires a filter bypass. Staff are also investigating and sourcing any equipment including replacement parts and sand that may be required.

Council anticipates being able to make temporary repairs with a plan for a filter renewal in the short term. A new filter would require significant investment.

In addition, we will be installing further disinfection at the plant, such as UV, as a final barrier to treat the water.

Staff are currently pricing the most cost effective option for this work.

Water tank

A bigger water tanker has replaced the small water tank and it is available in Tapanui, next to PGG where you can fill your own clean containers with drinking water.

This notice will be in place until we are satisfied that the water being received at the plant is consistently clear. We will provide an update when we are able to do so.
