Sewerage systems

Sewerage systems

Sewerage systems in South Australia comprise:

Gravity sewerage systems and sewage pumping stations

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.

    We’re improving your services and undertaking maintenance work in Direk. Sometimes our crews need to temporarily interrupt the water supply to our customers and/or manage traffic while they are working. Temporary traffic management may remain in place until reinstatement of the impacted road is complete. We always aim to minimise inconvenience by restoring services as safely and quickly as we can.
