Regional Pressure Management Programme
Water pressure management reduces water use and loss. It extends the life of pipes and reduces new leaks, helping keep water in the pipes and reduce demand

Wellington Water has a regional programme to plan and implement water pressure reduction on behalf of councils.
Planning is underway for pressure reduction in multiple suburbs across Wellington City, Lower Hutt, Upper Hutt and Porirua.
The first area we’re looking into is in Wainuiomata (in and around Meremere St). We plan to do this work in the 2025/26 financial year pending final design checks – you’ll hear more from us on this by late 2025.
Please see the ‘background’ section for our full schedule of works.
The purpose of the regional pressure management programme is to achieve more efficient water use. We want water pressure to be at the right level for use in homes and businesses (including for firefighting purposes), but we don’t want the pressure to be higher than it needs to be.
We use modelling techniques and water pressure testing out in the field to understand where pressure is right, and where it’s too high. We then apply pressure reduction in areas where it’s too high. We prioritise areas where we can achieve the highest volume of water savings in the most efficient way.
The programme will play an important role in conserving water, and delivering value for money to ratepayers by:
-
Reducing leakage in the water network
-
Extending the life on water pipes and other infrastructure
-
Reducing the number of pipe bursts
Water pressure varies across the region, depending on a range of factors such as location and elevation. Having pressure management valves that are operational and in good working order is another key factor.
