This scheme serves the immediate Governors Bay community of around 750 residents living along Main Road to approximately 350 metres short of Church Lane.

The treatment plant is located approximately 400 metres south of the Governors Bay wharf, above the foreshore.

Treatment

Wastewater from Governors Bay receives primary and secondary treatment within the plant followed by ultra-violet (UV) disinfection, before being pumped through a harbour pipeline to the Lyttelton wastewater treatment plant for further treatment and disposal.

The Council is underway with the Lyttelton Harbour wastewater scheme, which is a programme of work to be completed in 2022 that will see this plant decommissioned, with all of the wastewater from Governors Bay, Lyttelton and Diamond Harbour being pumped directly to the Christchurch wastewater treatment plant.


Consent monitoring

The main resource consent for discharge to the harbour (CRC101760) expired in December 2018. It included requirements for monitoring treated wastewater and the area receiving the discharge (receiving environment). Historical monitoring data is provided in the tables and graphs below.
