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

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


Wastewater from Governors Bay receives primary and secondary treatment within the plant followed by ultra-violet (UV) disinfection, before being discharged through an outfall pipeline into the harbour. Sludge is regularly removed and transported to the Christchurch Wastewater Treatment Plant for processing into biosolids.

The Consent

The main resource consent for discharge to the harbour (CRC101760) expires in 2018. Council has a programme of work that will be completed in 2022, that will see this plant decommissioned, with all of the raw wastewater from Lyttelton Harbour being pumped directly to the Christchurch Wastewater Treatment Plant. The Governors Bay plant will be closed in 2018.

Consent monitoring

Resource consent CRC101760 sets out requirements for monitoring treated wastewater and the area receiving the discharge (receiving environment). Samples are taken and analysed on a regular basis. The volume of wastewater leaving the plant is recorded continuously. Together these provide an indication of how the plant is performing and whether there are any potential adverse effects of the discharge on human health or the environment.

Monitoring data is provided in the tables and graphs linked to below:
