The Risk of Cryptosporidium to Sydney's Drinking Water Supply

Publisher Summary To protect the quality of drinking water in Sydney, the Sydney Water Corporation (SWC) and the recently created Sydney Catchment Authority (SCA) have adopted a catchment to customer risk management approach after the Cryptosporidium water crisis in 1998. In Sydney such an approach involves close collaboration with the New South Wales Department of Health (NSW Health), as well as the consortia managing several of Sydney's large water filtration plants (WFPs) under Build-Own-Operate (BOO) contracts. This chapter presents a paper, which aims to provide an update of the main actions that have been taken since the water crisis in Sydney in 1998. These updates need to be in: the catchments, water treatment plants, distribution system, and analytical laboratories for Cryptosporidium analysis.
