Working with Councils to provide recycled water to
regional recreational spaces
Unlike many inner or metropolitan council areas, residents of some rural and
regional locations cannot assume that they are connected to an externally
managed sewer system. Many factors contribute towards this, including
low-density living, the age of many dwellings, and topography that is not
supportive of sewer networks.
On behalf of rural and regional Councils, TRILITY manages multiple
Community Wastewater Management Systems (CWMS), formerly known
as Septic Tank Effluent Disposal Scheme (STEDS). STED schemes were first
developed to overcome public health and amenity problems associated with
failing or inadequate septic tank soakage trenches. Because these schemes
offered an affordable alternative to sewerage, they have been retained,
developed, and maintained across some Councils in South Australia.
One of our more recently awarded contracts is the Adelaide Hills Council
Kersbrook Community Wastewater Management System (CWMS), where our
Lower Riverland Team operates and maintains the Kersbrook re-use pump
station. The Kersbrook CWMS is an essential wastewater disposal service
provided to around 1,800 households and businesses across the region.

The septic tank effluent from the Kersbrook township pump station is
pumped up the hill to primary treatment ponds. The STEDS water is
treated using basic oxidising lagoons to treat incoming wastewater through
design-enhanced biological processes. The re-use water then gravitates to
the local Soldiers Memorial Oval storage tanks, where
sodium hypochlorite is dosed. The treated water is then irrigated overnight
onto the oval with an irrigation controller run by the oval caretakers. The
images below highlight the significant contrast between the non-irrigated
surroundings and the oval. The oval is used by the local hills football teams
and the Adelaide-based Sturt SANFL club for games and training.
We pride ourselves on the expertise we bring to Councils to manage
the CWMS services we provide and the additional services in bringing
much-needed recycled water to their communities’ recreational facilities.
