Update on Havelock North water supply issues

Prompt action has been taken to ensure the Havelock North water supply is safe for residents.

An outbreak of a gastro bug emerged in Havelock North late last week. Test results received today (Saturday, 12 August 2016) linked to the outbreak to the Havelock North water supply.

"Swift action was taken to address water safety as soon as there was suspicion that the water supply might be the source of the outbreak,” says Mayor Lawrence Yule. "Chlorination was initiated late on Friday afternoon to kill bugs that might be in the water supply, such as Campylobacter."

"Work was then done with the District Health Board on what the cause might be," says Mayor Yule. "While the identity of the bug is not yet known, it was decided to issue a boil water notice as an additional precaution."

Health authorities advise that the water in Havelock North is safe to shower in, and that the combination of chlorination and boiling water makes it safe to drink. Tests that will show the identity of the bug are not expected to be available until Monday or Tuesday.

"We are also keen to reassure people in Hastings and Flaxmere that their water is safe," says Mayor Yule. "Valves on the pipes connecting Hastings and Havelock remain closed, and the Hastings supply has consistently tested clear. The Hastings and Havelock North water supply systems are operated separately.”

A contamination problem appears to have occurred at the Brookvale bore field in the number one and two bores. This is the first time these bores had been affected. The number three bore, which has shown signs of contamination in the past, has been closed for investigation and remediation since October 2015.

Routine tests conducted (Tuesday 9 August) after last weekend’s storm event showed the Brookvale supply to be clear. Additional test results received this morning showed indicators of contamination.

Council continues to work with the District Health Board on this issue, and the organisations will provide further information to the public as it comes to hand. Council environmental health officers have been in contact with food supply premises, and Council contractors are visiting properties with water tanks connected to the Havelock supply to help ensure water in those tanks is treated.
