Pukekohe Sewer Trunk Upgrade


This project was to upgrade the trunk sewer between Pukekohe and the Pukekohe Wastewater Treatment Plant in order to increase its capacity, providing for planned future growth in the area. This upgrade that we provided control and instrumentation services for has meant that this section of the sewerage system can now handle a population of approximately 48,000. This will keep Watercare’s wastewater reticulation systems in line with Auckland’s projected growth. This Upgrade required work on the Pukekohe Pump Station, the Buckland Pump Station, and the Trunk Sewer itself.

McKay was contracted by Fulton Hogan for the design, supply and installation of the electrical and instrumentation works, which included:

  • Install connection to power supply, as well as standby generators at each site
  • Full installation of the main switchboards and motor control centres
  • Design and installation of a full package of instrumentation and telemetry systems across all sites
  • Lighting design and installation
  • Installation of all ducting and cabling for mains, instrument, control, data, communications and security

For this project, we provide not only a design solution for a single site, but one that incorporates and connects a whole network of sites, allowing the control and instrumentation systems we have provided to be utilised from anywhere along the trunk. These sorts of integrated design solutions that allow facilities to be used at even higher efficiency are thanks to McKay’s experienced engineers, electricians, and instrumentation technicians.
