Work flows on Mairangi Bay Pump Station

Watercare and its construction partner, Pipeline & Civil, have begun the installation of a 160-metre pipeline as the final pieces of the Mairangi Bay Wastewater Pump Station slot into place.

Taking shape on the corner of Sidmouth Street and Montrose Terrace, the $22.5 million pump station will significantly reduce wet weather overflows in the area and is on track for construction to be completed in October.

Watercare project manager, Dirk du Plessis says with much of the electrical, mechanical and odour control fit outs is well underway. 

“Once completed, the pump station will be able to handle flows of up to 625 litres per second, compared to the existing station’s flow rate of 340 litres per second and will have an integrated storage wet well of 230,000 litres.

“This extra pumping capacity and storage will significantly reduce the likelihood of overflows into Mairangi Bay in wet weather when stormwater can overload our networks. 

“We’re on track to finish construction in October and hope to have the pump station in operation before summer kicks in,” he said.

The current pump station on Sidmouth St will be demolished once the new pump station is operational.

Besides the practicalities and benefits of the new pump station, Mr Du Plessis says it will also have street appeal.

“At the beginning of the project, we wanted to make sure the pump station would not only reduce wet weather overflows and cater for growth but also blend into the reserve’s surroundings,” he said.
