We have three types of CWMS systems in Alexandrina: gravity sewer, vacuum sewer systems and STEDSs (Septic Tank Effluent Disposal Schemes). Wastewater must pass through a septic tank at properties connected to a STEDS network.
The table below shows CWMS systems by suburb. Notice that some suburbs have more than one type of CWMS system.
