Brewarrina Shire Council operates a sewage treatment plant in Brewarrina. The property is located on Charlton Road with rural properties surrounding the plant.
The Brewarrina Sewerage Treatment Plant (STP) is a trickling filter system with oxidation ponds. The STP operates as a no release site with effluent reuse through an irrigation system on a nearby property.
The STP operates under EPL 1748 which is issued under Section 55 of the Protection of the Environment Operations Act 1997 by the NSW Environment Protection Authority (EPA).
The introduction of the Protection of the Environment Legislation Amendment Act 2011 (POELA Act) in February 2012 requires that holders of EPLs maintain a Pollution Incident Response Management Plan (PIRMP).
