Update: 9 May

The reservoir is at satisfactory levels and Martinborough residents no longer need to conserve water. Wellington Water and the Council thank you for your assistance.

7 May 12pm

The Ruamahanga Water Treatment Plant operated without incident overnight and reservoir levels are at a satisfactory level.

Residents should continue to conserve water where possible.

The water treatment plant’s chlorination system is being monitored and residents can be assured that the water is safe to drink.

Update: 6 May 2022, 10pm

Wellington Water advises that the Ruamahanga Water Treatment Plant is back in operation and is refilling the reservoir in conjunction with bulk water tankers.

Martinborough residents continue to be requested to conserve water. They are assured the water is safe to drink.

Wellington Water was preparing to stand down the tankers at 10pm, provided the plant was operating without problems. The level of the reservoir is expected to be sufficient to cover the morning peak demand.

This afternoon’s problem stemmed from a chlorination dosing fault. The plant will not run without chlorination so Wellington Water has been drawing on treated water in the reservoirs to supply Martinborough. 

The water treatment plant’s chlorination system is being monitored and another update is due tomorrow morning.

4pm: Wellington Water has advised that a chlorination dosing fault has developed at the Ruamahanga Treatment Plant and it is asking Martinborough residents and businesses to conserve water urgently to avoid draining the water supply.

While engineers address this matter, the drinking water treatment plant is out of service.

There is no risk to health and we will bring you an update shortly.
