Reservoir project on track for completion in Winter

Community Reference Group

The Community Reference Group is a forum for the community and stakeholders to be actively involved in the project planning and management. Established as part of the project’s consenting requirements, the CRG is made up of representatives of key residential and community organisations and meets regularly with the project team.

About

Omāroro will provide critical additional bulk water storage for Wellington’s central business district area and low-lying suburbs to improve operational and disaster resilience.

Omāroro involves constructing:

  • a 35 million litre buried concrete reservoir in Prince of Wales Park in the Town Belt
  • connecting it to the existing water supply with a supporting new pipeline corridor along Wallace Street
  • renewing of local water supplies, stormwater pipes and wastewater pipes in the area

Partners

Omāroro is a joint project led by Wellington Water, which manages the city’s drinking water, stormwater and wastewater; working with Wellington City Council and the Greater Wellington Regional Council 

Iwi Taranaki Whānui ki Te Upoko o Te Ika (Taranaki Whānui) and Te Rūnanga o Toa Rangatira Incorporated (Toa Rangatira) are strategic partners in the council’s decision making process as our Tiriti o Waitangi partners.

And it involves the community. Right from the start, we’ve worked closely with residents and businesses most affected by the project ensuring they are informed and able to have input every step of the way.  The Community Reference Group is a forum for active community and stakeholder involvement during the construction phase.

Why resilience?

It’s important for a city to have enough water stored to allow for at least two days’ normal use and to enable repairs, maintenance and upgrades to be done without disrupting supply.

That’s called operational resilience and right now our city’s storage capacity is not up to scratch.

The city’s water supply network is also vulnerable. Underground pipes and reservoirs could be badly damaged in a significant earthquake and as a result some suburbs could be without drinking water for more than 100 days.

Our resilience programme

Omāroro is part of Wellington Water’s ongoing work to improve the resilience of the region’s water supply network and increase water storage in case of a disaster.

Over the last two years, we have established a new above ground emergency water network that will supply more than 400,000 people across Wellington from day eight following a disaster.

It’s important to remember that following a major earthquake, the first thing people rely on is themselves and their families, so storing water is a must for every household.

You should have 20 litres of stored water for every person, every day, for at least seven days.

All Updates

10 November 2023

All work and planting on site has been completed.

Once the grass on the sports fields has established, fences will be removed and a formal opening ceremony will be held, including handover of the site in the Wellington Town Belt back to Wellington City Council and the public.

 

3 May 2023

Backfilling of Omāroro Reservoir is nearly finished and work is underway on the final phases of reinstating the playing fields and planting natives around the sides of the site.

The new 35 million litre bulk water storage facility, which was put into service in December last year will be fully buried once completed. Backfilling, using excavated material from the site  started in early March, and the whole project will have taken three years by the time it is fully completed in Winter this year.

Along with new playing fields and native plantings, the final phase includes a five-year project under which the landscape will be monitored and managed to ensure it is fully restored and revegetated.

Its completion is a big step towards building more resilience into Wellington’s water supply network.

The reservoir will extend the amount of time the central business district has a water supply from 24 to 48 hours in a situation where the main supply of water from the Hutt Valley is cut or there is an unforeseen treatment plant. 

It is also vitally important following a major emergency event such as a large earthquake, as it provides critical drinking water to support the community through the immediate survival and stability phase, and then to a longer-term restoration and recovery period.

A formal opening ceremony will be held once the project is completed, including handover of the site in the Wellington Town Belt back to Wellington City Council.
