Pressure sewer systems

Pressure sewer systems

If you do not have access to a standard gravity-fed connection to our sewerage network, you may have the option to install a pressurised sewer system to connect. Use of a pressurised sewer system is subject to our approval.

The developer (or representative consultant) must provide sufficient information to enable a proper assessment to be undertaken.

If your property is in a low pressure sewer scheme area with a boundary kit between the property and our sewer main in the street, there are two possible connection scenarios. To find out if your property is in a low pressure sewer scheme area and to determine your connection responsibilities, or to discuss alternative sewer connection options, please call us on 1300 SA WATER (1300 729 283).

Boundary kits installed before 1 January 2018

Property owner responsibilities

You are required to pay:

  • the cost for the pressurised sewer system on the property, before connecting the private drain. (A cost estimate for the pressurised sewer system is provided once an application to connect has been made)
  • for a licensed plumber to install the private drain from the house to the tank
  • for electricity to operate the pump.

Our responsibilities

We own, install and maintain all infrastructure from, and including, the underground retention tank up to, and including, the sewer main.

Boundary kits installed after 1 January 2018

Property owner responsibilities

You are responsible for:

  • the cost and installation of all infrastructure from the boundary kit to the house (as shown on the previous page) in accordance with our specifications
  • the costs associated with any extension of the sewer network and/or new boundary kits. For any new boundary kit, the owner is required to pay the estimated sewerage connection fee before connecting the private drain
  • ongoing maintenance of all infrastructure from the house to the boundary kit
  • the cost of electricity to operate the pump.

Our responsibilities

  • We own, install and maintain all infrastructure from, and including, the boundary kit to the sewer main.

If a pressurised sewer system is approved, the WSAA  Pressure Sewerage Code of Australia (WSA 07-2007) is used as the basis for design and construction of a system. We have some additional requirements which are detailed in the SA Water Supplement to WSA 07-2007.

The WSAA drawings cover the more detailed requirements and provide ‘deemed to comply’ solutions.
