Community Wastewater Management Scheme (CWMS)
The townships of Bordertown, Keith, Mundulla and Wolseley are serviced by Council owned and operated community water management systems (CWMS). The systems are designed to collect, treat and dispose of effluent and waste water from septic tanks on individual properties. The collection system is a network of pipes and pumping stations which transport the effluent from the septic tanks to the oxidation lagoons. The lagoons store and treat the waste water by aerobic action and during periods of high use flow into the adjacent wetlands where it evaporates.
The systems consist of the following infrastructure:
Pump Station and associated assets
The schemes are licenced by the Environmental Protection Authority ensuring the systems meet environmental standards.
Council strives to manage the service in the most cost effective way through the development of a CWMS Asset Management Plan which spells out the future cost of maintaining the systems while meeting the requirement of modern day standards. Council has completed a 3 stage pump station upgrade program. This consisted of upgrading 20 pump stations to meet modern day standards. The upgrade includes connecting each pump station to a remotely managed supervisory control and data access system (SCADA). The system allows Council staff to monitor each pump station remotely and respond to incidents much quicker reducing the risk of effluent overflow causing environmental damage or community health issues.
Wolseley Water System
Council owns and operates a gravity fed low-pressure water supply systems for the residents of Wolseley. Initially installed by the Wolseley RSL & Community Club in approximately 1989, Council took over care and control of this system in 2001. The reticulation system comprised of a network of pipes, two bores with submersible pumps and two overhead tanks provide non-potable through a water meter to connected properties within Wolseley. The water is of the quality for domestic use in washing, toilets and gardens. Water is not to be used for drinking purposes as it is not a potable water supply.
CWMS Pricing Policy and Schedule
In accordance with the requirements of the Water Industry Act, the Council publishes an annual pricing policy statement and pricing schedule, in the format required by the Essential Services Commission of South Australia. Please click on the documents below to access the information.
