Pressure sewer systems explained

Pressure sewer systems are not common across the city and are generally located in areas where a conventional gravity system is not a viable servicing option such as flat or rocky terrain.

Pressure sewer systems operate like a normal sewerage system taking waste liquids from your toilet, sink, shower, bath, dishwasher and washing machine and transferring it to the reticulation system or treatment plant.

The system contains a:

  • Boundary kit
  • Pump unit
  • Control panel
  • Alarm system
  • Pressure sewer unit

Your pressure sewer systems and all relating components are owned and maintained by Shoalhaven Water and at no times are they to be adjusted, serviced, or relocated by any persons other than Shoalhaven Water operations staff.
