The community of Kinglake West was on a waiting list to receive government financing for a new sewer system
when, in 2009, a disastrous fire swept through the area. The damage was so extensive that funding for a wastewater
collection system was expedited. The new system needed to be up and running as soon as possible, without
being an undue financial burden to homeowners.
An Orenco® Effluent Sewer – the first in Australia – was installed. The sewer includes an Orenco STEP (Septic
Tank Effluent Pump) package in an underground tank, which provides passive, primary treatment at each residence.
Small-diameter force mains move the effluent from each home to the community’s treatment facility.
Because an effluent sewer transports only liquids, its mainlines are typically just 50-100 mm (2-4 in.) in diameter
and can be installed quickly and easily with light-duty equipment. This allowed the wastewater collection system
to be completed in a relatively short period of time, despite the area’s hilly terrain.
