In keeping with our global approach to managing wastewater overflows during heavy rain events, we’re working with private property owners in two Karori sub-catchments, to fix problems contributing to stormwater going into the wastewater drain.

By actively working to stop rainwater getting into the wastewater pipe network, we aim to reduce wastewater flow within the Karori wastewater catchment - towards reduction in wastewater overflows at the Western Wastewater Treatment Plant (WWTP).
