Ulladulla New Wastewater Treatment Plant, Kings Point, New South Wales

Ulladulla New wastewater treatment plant is located in Kings Point, near Ulladulla, on the south coast of New South Wales, Australia. The plant serves a population of approximately 5,144 people and is part of the municipal wastewater infrastructure managed by the Shoalhaven City Council. It operates under the regulatory framework of the New South Wales Environment Protection Authority, which sets discharge standards for inland and coastal waters. The plant's designed capacity is 1.00 megalitres per day, reflecting its role as a small to medium-sized facility. Australian wastewater treatment plants of this scale typically employ secondary treatment processes such as activated sludge or lagoon systems to meet state environmental protection license conditions. The plant's operational status indicates it is actively managing wastewater from the local community. The treated effluent from Ulladulla New is discharged into the local catchment, which ultimately drains to the Tasman Sea via coastal streams and estuaries. This coastal discharge requires careful management to protect sensitive marine ecosystems, including seagrass beds and rocky reef habitats that support diverse aquatic life. The plant plays a key role in maintaining water quality in the region's coastal waters.

The plant discharges into the local catchment that flows to the Tasman Sea, a coastal water body supporting diverse marine life including fish, crustaceans, and migratory seabirds. The receiving environment includes estuaries and nearshore habitats that are ecologically sensitive to nutrient inputs. Effective treatment is essential to prevent eutrophication and protect the health of downstream coastal ecosystems.
