Sydney Water, formally, Sydney Water Corporation, is a New South Wales Governmentowned statutory corporation that provides potable drinking water, wastewater and some stormwater services to Greater Metropolitan Sydney, the Illawarra and the Blue Mountains regions, in the Australian state of New South Wales. History The origins of Sydney Water go back to 26 March 1888 when the was enacted and repealed certain sections of the relating to water supply and sewerage, thereby transferring the property, powers and obligations from the Municipal Council to the Board of Water Supply and Sewerage. Name changes The forebears of Sydney Water include: Board of Water Supply and Sewerage (18881892) Metropolitan Board of Water Supply and Sewerage (18921925) Metropolitan Water Sewerage and Drainage Board (19251987) Water Board (19871994) which had also been the colloquial name for the organisation for much of its history in the 20th century, and persists among longer term employees and older members of the community to this day Sydney Water Corporation Limited (19951999) Sydney Water Corporation (1999present) – with "Limited" being dropped when the corporation changed from a state-owned limited company to a statutory state-owned corporation. Water supply management Sydney Water's management received extensive criticism following the 1998 Sydney water crisis regarding what was believed to be the large scale contamination of Sydney's raw water supply. The supposed contamination was heightened levels of cryptosporidium and giardia in Sydney's Warragamba Dam. This meant the public had to take extra steps in their own homes to ensure tap water was safe to drink. After this event, the Sydney Catchment Authority was created to manage Sydney's dams, reservoirs, raw water and catchment areas. The Chairman of Sydney Water, David Hill resigned ten days after the crisis and denied any responsibility, claiming he was leaving only to concentrate on his political career. On 1 January 2015, The Sydney Catchment Authority was merged with State Water Corporation to form WaterNSW so that WaterNSW is now the supplier of raw water to Sydney Water. In June 2022, Sydney Water started working decentralized greywater recycling system producer Hydraloop for reducing water use. Water restrictions Since June 2019 Sydney Water replaced water restrictions with Water Wise Rules. The Rules are: Level 1 water restrictions (subject to change at any time by NSW Government) All hoses must now have a trigger nozzle. Handheld hoses, sprinklers, and watering systems may be used only before 10 am and after 4 pm on
