How to reduce your wastewater
Rain entering the wastewater network
Rain and groundwater can sometimes get into our wastewater pipes from illegal house connections, such as incorrectly connected stormwater systems, and broken sewer mains. You might also hear this referred to as inflow or infiltration.
A common point of entry for stormwater into the wastewater network is through a gully trap. Council is actively trying to reduce inflow and infiltration by regularly monitoring our network with CCTV cameras and smoke testing to help identify locations where stormwater enters the system.
