Mairangi Bay Wastewater Pump Station

Watercare Services – Mairangi Bay Wastewater Pumpstation

The Sidmouth Street Mairangi Bay wastewater pumpstation is a Watercare key facility, collecting and pumping all the North Shore’s east coast bays sewage to the Rosedale treatment works. The station was designed to cater for capacity growth up to 2060 and completed in March 2024.  As part of the Pipeline and Civils team, GRS Consulting were responsible for the electrical, instrumentation, and control design. The station comprises a large wet and dry well, with 4 x 250kW pumps.

The challenge of this project was to produce a good design despite tight space constraints.

The project required careful co-ordination of services alongside all required functionality for a Watercare critical facility.
