DECENTRALISED WASTEWATER RECLAMATION FACILITIES AND NETWORK FOR NATIONAL TRUST LISTED VILLAGE

摘要

Kangaroo Valley Village is located within Shoalhaven City on the south coast of New South Wales. Historically the village had no reticulated sewerage collection system. Shoalhaven Water (SW) facilitated the Kangaroo Valley Sewerage Scheme (KVSS), consisting of a pressure sewer system (for 250 lots) and a new advanced water reclamation facility. This paper reviews the GHD design options (and economics) for connecting to the existing centralised wastewater facility versus a new decentralised reclaimed water facility, as well as design considerations for selection of the dual biological and membrane bioreactor process configuration to meet large variations for high seasonal tourist influx (i.e. 530 kL/Day) down to normal residential capacity (i.e. 100 kL/Day). Data provided demonstrates the large reduction in nutrients and pathogens that enable the wastewater to be beneficially reused, as well as meet Sydney Water Catchment Authority's license requirements.
