Diffusers in the aeration tank at Burwood Beach Wastewater Treatment Plant.
Project overview (project now complete)
Burwood Beach Wastewater Treatment Works (WWTW) is Hunter Water's largest treatment plant. The treatment process consists of preliminary and secondary treatment, before release to the ocean 1.5kms off-shore.
Last year a State Government report rated all seven local Newcastle ocean beaches as 'Very Good' or 'Good'. Merewether and Burwood North and South performed well. It was noted, however, that water quality declined when more than 20mm of rain fell, and occasionally an unusual mix of ocean currents and winds can combine to push off-shore water towards the beach.
Hunter Water is preparing to install a UV disinfection system at the Burwood Beach WWTW to further improve water quality at Newcastle's beaches. The state-of-the-art system will use ultraviolet light to destroy bacteria, viruses and protozoa.
Design of the new UV system has commenced and construction will be completed in 2016.
