The City of Kalgoorlie-Boulder is one of the largest local government re-users of effluent water in Australia.
The South Boulder Waste Water Treatment Facility treats wastewater from our local sewer system and produces an effluent that is used for watering City parks and gardens. It also supplies effluent water to government and private organisations, including the mining industry, to minimise the demand on the Goldfields and Agricultural Water Pipeline Scheme.
The plant was transferred to us from the Water Corporation in April 2004.
