GREATER GREYMOUTH WATER SUPPLY - Precautionary BOIL WATER NOTICE

Commencing 28 August 2026 at 2pm until further notice

Monday, 6pm

The precautionary BOIL WATER NOTICE for the Greater Greymouth supply remains in place.

A third clear test result was received today.

This means we have achieved three clear days of testing.

However, additional flushing of the mains will be done in Kaiata tomorrow.

A final review of results, monitoring information and trends is underway, to determine if the precautionary notice can be lifted.

The sample with E. coli was taken on Thursday as part of work being undertaken to connect the Kaiata water zone to Kaiata Park, and we have reason to believe it could have been a sampling error.

We apologise for any inconvenience.

Next update will be noon tomorrow.

Sunday. 4.20pm update: results from today are clear - the second set of clear results.

Next update this time tomorrow.

Note: a text alert will be sent out when the boil water notice is lifted.

Saturday, 6pm update:

The latest water testing results from nine Greater Greymouth sites are clear.

The Grey District Council yesterday issued a precautionary BOIL WATER NOTICE FOR THE GREATER GREYMOUTH WATER SUPPLY.

E. coli was detected in a sample taken in the Kaiata zone on Thursday, so the precautionary boil water notice has been put in place whilst further sampling is being undertaken.

The areas affected are Greymouth, Cobden, Blaketown, Boddytown, Karoro, South Beach, Paroa, Kaiata, Dobson, Taylorville, Stillwater, Runanga, Dunollie, Coal Creek, and Rapahoe.

Tests taken at the Greater Greymouth Treatment Plant, Greymouth, Cobden, Runanga, Rapahoe, Kaiata, Dobson, Taylorville and Stillwater are all clear.

Three clear days of testing are required before Council can consider lilting the precautionary boiled water notice.

The sample with ecoli was taken on Thursday, as part of work being done to connect the Kaiata water zone to Kaiata Park, and we have reason to believe it could be a sampling error.

Whilst it is possible it is a sampling error, Council is obligated to take a precautionary approach to ensure public safety. This has resulted in the precautionary boil water notice.

We will update people around 5pm tomorrow in this post – check the comments for information on how to turn on notifications.

We apologise for any inconvenience.
