The sewage passes through a number of treatment procedures after it enters the sewage treatment plant. Firstly, sewage from Cronulla and Kurnell passes through screens which separate large objects or debris from the water. These screens are then transferred to tanks where the water is removed, and are taken by truck to a landfill site. Sewage that has passed through the first screen enters the grit tanks where grits, or fine particles, is removed. The grit is then taken to be dewatered and subsequently trucked to a landfill site. Meanwhile, the sewage still in treatment flows from the grit tanks to sedimentation tanks in which chemicals are added to assist the separation of sludge from waste water. The sludge is then transferred to a sludge digester. From the sedimentation tanks the waste water continues through fine screens which filter out any remaining solids. The solids are sent back to the screenings dewatering unit and also trucked to a landfill site. The treated waste water is released at Potter's Point. This completes the process of sewage treatment at Cronulla.
