Omāroro reservoir

The three waters work programme

Wellington Water, a Council Controlled Organisation, manages our water, wastewater and stormwater (three waters) services and delivers big improvement projects on our three waters network. There are some significant capital projects scheduled and we have reviewed our programme to make sure the funding levels and timing are appropriate.

Omāroro reservoir

This major new reservoir is essential for operational security and emergency water supplies, and to support projected growth in the CBD area. The estimated cost for this project has increased due to the requirements of construction in the Town Belt, the complexity of upgrading associated pipelines along a busy inner city transport route, and the rise in costs being seen across all major infrastructure construction work. Expected capital expenditure of $58.15 million over four years from 2019/20 is proposed, up from $40.85 million in Our 10-Year Plan. When complete, Omāroro Reservoir will provide sufficient safe drinking water in secure storage to allow for maintenance and network repairs to be made should supply from the Hutt Valley be disrupted. It will also provide emergency water for Wellington Hospital if there is a major seismic event.
