General Description
Sewerage
Catchment:
-
Potter Point outfall is the discharge
point for the Cronulla STP, which services areas from Kurnell and
Cronulla in the east to Illawong, Sutherland and Heathcote in the
west. It does not provide services to Bundeena, Mainbar, Sandy Point
or the industrial areas of the Kurnell Peninsula. Cronulla STP also
services the township of Helensburgh, which lies within the Wollongong
local government area.
Sewage
Treatment:
-
Cronulla STP is an advanced primary
treatment plant and provides screening, primary sedimentation and
removal of oil, grease and floatables. The removed sludge is digested
and dewatered. Enhanced suspended solids and grease removal is
enhanced by a CAS (chemically assisted sedimentation - the addition of
ferric chloride and polymer to improve removal of suspended solids and
grease) process. Effluent is passed through fine screens before
discharge.
