Bateau Bay sewerage treatment plant was built in the late 1960s when at the time there was very little nearby development. Treated sewage is discharged into the sea off Bateau Bay at Wonga Point. Some people protest that sewage may end up on the nearby beaches. There has been no major sea pollution from the plant, there is a smell though over the eastern side of the suburb. The treatment plant has operated for longer than most people have been resident.
