CWMS connection

Properties in The Barossa Council may be serviced by the Community Wastewater Management System (CWMS).

Council’s CWMS is a wastewater management system, operated under the Water Industry Act 2012 as a fee for service, sewerage treatment system.

Sewer from your property flows into the septic tank on your property, which is an underground tank made from either concrete, bricks, or plastic. Within the septic tank, the liquid and solid portions of the sewerage are separated. The solids settle to the bottom of the tank where naturally occurring bacteria convert the material into sludge. The liquid effluent passes out of the septic tank, via pipework to the boundary connection outlet drain, into Council’s CWMS.

The effluent water from each property is treated as per EPA requirements to recycled water standards, for use by local irrigators and on Council reserves. This provides a guaranteed water supply in times of drought and reduces our local impact on the River Murray and is a valuable water supply in times of Bushfires.

If you are planning to develop i.e. sub-divide, build, alter an existing dwelling, install and/or alter a spa or swimming pool, or connect your property to the Community Wastewater Management System you will need to apply for construction or modification on council property, which is separate to a development application.

If your property is connected to the CWMS, as part of the services included within your annual rates, Council will arrange for an EPA licenced contractor to desludge your septic tank. This will occur once every four years (maximum) dependant on the size and/or requirements of your system.

The Boundary Connection point (I.P.) is located on the outlet drain of the septic tank and is your property’s connection to the Council CWMS. It provides an important access point to the CWMS network and is utilised for repairs and removal of blockages.

Please ensure that your boundary connection (I.P.) has clear access at all times.

Do not cover or build over your boundary connection points (I.P.).

If you have an overflow or blockage, locate your boundary connection point (I.P.) and remove the lid.

If there is no water flow observed through the I.P. when you turn on a tap in your house, the blockage is most likely on your property. Please contact a licensed plumber to clear the blockage.

If water has filled the IP, the blockage is most likely in Council’s drain. Please contact Council to arrange for one of our CWMS Officers to assess and clear the blockage.

For 24hr Emergency assistance please call Council on 8563 8444.

If your property is connected to the CWMS, as part of the services included within your annual rates, we will arrange for an EPA licenced contractor to desludge your septic tank. This ensures the effective operation of the septic tank and maintains the efficient operation of the CWMS. This will occur once every four years (maximum). Dependant on the size and/or requirements of your system.

Property owners are requested to ensure the septic tank lid is exposed and open to contractors immediately prior to desludging. Council's contractor will provide advance notice of the required service dates.

Trade waste is any used water and substances from commercial, industrial, business trade or manufacturing activities. Trade waste often has other substances in it, such as solids or chemicals that may not pass through a septic tank and may cause damage to the CWMS network.

The two main elements requiring assessment are the quality and quantity of the trade waste in conjunction with its proposed connection point to the CWMS network.

Please refer to the Trade Waste Fact Sheet for further information.
