Pressure Sewer Systems

Pressure sewer systems are small on-property units that collect, grind and pump household sewage into a pressurised reticulation system in the street which then conveys the household sewage on to a treatment plant.

Pressure sewerage systems are generally in areas where a conventional gravity system is not a viable servicing option such as flat or rocky terrain

The pressure sewer unit and all relating components are owned and maintained by Shoalhaven Water in their entirety. At no times are the pressure sewer units or other componentry to be adjusted, serviced or relocated by any persons other than Shoalhaven Water operations staff.

A development that is identified as requiring the installation of a low-pressure sewer unit (PSU) or any proposed work to an existing PSU must lodge an application with Shoalhaven Water prior to commencement of any works, this will include installation, modification or relocation of works. 

How do I proceed to have a PSU installed?

Step One – Submit the Pressure Sewer Pump Unit Application to Shoalhaven Water by email or by visiting our office in Nowra or Ulladulla.

Step Two – Given approval, a payment advice will be issued (where required).

Step Three - Installation of the pressure sewer pump unit will proceed once full payment has been received. All work will be carried out by Shoalhaven Water within 8 weeks of payment.
