WDC Pump Station Emergency Storage Tanks

Waikato District Council

Project Scope

This project was for the installation of Waste Water Emergency Detention tanks at 4 Pump Station sites in Waikato.

  • Regent Street, Ngaruawahia
  • Thomas Street, Ngaruawahia
  • Marine Parade, Raglan
  • Nero Street, Raglan 

Works involved the design and installation of large diameter fibreglass underground storage tanks, connections to the existing wastewater pump stations, electrical instrumentation and commissioning.

Due to the location of some of the tanks a sheetpiled cofferdam was required to install the tanks at the required depths, up to 4.5m deep.



The use of fibreglass tanks as opposed to the concrete tanks specified resulted in a more cost-effective design-build solution.


This project was completed in March 2015.
