Sewerage systems
Sewerage systems
Sewerage systems in South Australia comprise:
- Gravity and Pressure Sewer Systems(up to DN 300)
- Packaged Pumping Stations (refer Gravity and Pressure Sewer Systems page)
- Pressure Sewer Systems
- Vacuum Sewer Systems
Water recycling is a critical issue and minimising wastewater salinity is an important objective for us.
Gravity sewers will always be our preferred option, and consideration of the designing of sewer mains below the existing groundwater table must be taken into account. This reduces saline infiltration into the system. Pressure sewer systems or vacuum sewer systems can be considered if a gravity sewer will compromise water recycling.
