Pressure Management Project

Overview
Current status
Background

On behalf of Wellington City Council, we are working to minimise areas of excess water pressure in the water distribution system to reduce leakage and water consumption and help increase the life of our water network.

Current Status

We have completed the physical works on the pressure management project which recently took place in parts of Brooklyn, Johnsonville and Melrose.

This pilot project involved installing pressure reduction valves in parts of the water network. This work just prior to December 2023. Please see the 'background tab' above for more information.

We're currently working on analysing the results of this pilot project and we'll share key insights and results once available.

If residents have any queries regarding the above work, please contact our Customer Hub (customer@wellingtonwater.co.nz), or on 04 912 4470. You can also contact Wellington City Council on 04 499 4444.

What's happening?

Wellington Water has an ongoing programme to improve pressure management across the region. Pressure management is usually done by installing pressure reducing valves to reduce water pressure within areas of the network. This is common both internationally and nationally, to reduce water use and loss, extend the life of pipes and reduce the number of leaks.

Three projects will serve as pilot studies to improve how similar projects can be delivered, by refining the costs and benefits of pressure management within the region, and informing further pressure management opportunities. Modelling indicates that pressure management within these zones may provide water savings of up to 300,000 litres per day, and reduce the number of new leaks by as many as 40 per year, as well as extending the life of the pipework.

What happens if our PRV has to be replaced or removed, who covers the costs?

I don’t know whether we have a PRV installed or not? Do I need to know?

We have a siphon hot water system that relies on mains pressure to siphon hot water from our water tank. Will the project affect this?

We have PRVs on a low-pressure hot water cylinder in our home. How will the project affect us?
