What CWMS is
The video explains what CWMS is and how it works.
Around 4,700 properties in the City of Tea Tree Gully are not connected to SA Water's sewer. Instead they are on a septic tank system that is serviced by Council's Community Wastewater Management System (CWMS).
The CWMS is a complex pipe network stretching 117 km over 70 zones.
Household waste from toilets, kitchens, bathrooms and laundries enters the septic tank on each property connected to the CWMS.
Solids settle to the bottom of the tank, while liquid waste flows into the CWMS network and then into an SA Water sewer main or an approved treatment facility.
Council routinely cleans the sludge from septic tanks about every four years to reduce the risk of blockages and keep them operating efficiently.
While the system is stable, like all utilities, it requires maintenance to remain operational.
