BOIL WATER NOTICE LIFTED - THOMPSON STREET, MOUNT COOK
BOIL WATER NOTICE LIFTED - THOMPSON STREET, MOUNT COOK

Wellington Water advises that the boil water notice has been lifted for all of Thompson Street and 77 Nairn Street, Mount Cook as of Tuesday, 17 June. 

We acknowledge it has been disruptive over the last few days. We want to thank all impacted residents for their understanding, patience, and co-operation during this time.

The public network has been flushed and tested over the last 72 hours. Testing results of the water quality over this period have come back confirming that water is now safe to drink without boiling. 

We are advising residents who have been away and are returning home to run a cold tap for a few minutes to flush their pipes and any appliances connected to the water supply. Header tanks should be drained and refilled. 

 
FAQ / Presence of asbestos fibres in our water pipe network

Presence of asbestos fibres in our water pipe network

Asbestos cement (AC) was used extensively within the pipe network following the Second World War, particularly in the 1960s and 1970s.  Asbestos cement pipes were an integral part of infrastructure investment in New Zealand until 1986, when manufacture and installation of AC pipes ceased.  AC water pipes are common, not only throughout New Zealand, but across the world.  The pipes are gradually being phased out, as we replace older pipes as part of our ongoing renewal and replacement project work.

Asbestos cement pipelines deteriorate over time, and asbestos fibres can be released into the water supply as the pipelines age.  This occurs over a long period of time.  We monitor and carefully control the Ph and alkalinity levels in the water at our treatment plants to minimise the impact of decay and internal corrosion on the pipe network.

 

Health Risk?

Wellington Water refers to the World Health Organisation's health advice and research. on the health risk associated with asbestos fibres in water pipe networks and drinking water.

Taumata Arowai - the water services regulator for Aotearoa - have not included asbestos on the list of determinants to measure as part of the Drinking Water Standards coming into force on the 1 July 2022.
