What Makes Pyrmont's Water Unique?
Local geology and source profile
Pyrmont's drinking water is supplied by Sydney Water, treated at the Prospect Water Filtration Plant incorporating a moderate Hawkesbury-Nepean component for the City of Sydney LGA inner harbour distribution in New South Wales. Water hardness in Pyrmont is measured at 88.5 mg/L — classified as slightly hard — within the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. Pyrmont — one of Sydney's most dramatically transformed urban precincts, the inner harbour peninsula home to The Star Casino, Google's Australian headquarters, the Pyrmont Bridge heritage footbridge, the Sydney Fish Market, the Darling Harbour waterfront, and a premium mixed-use residential and commercial community — receives slightly elevated supply from Sydney Water's inner harbour Prospect distribution.
Pyrmont's slightly elevated hardness reflects a moderate Hawkesbury-Nepean component in the City of Sydney inner harbour Prospect distribution blend. The Hawkesbury-Nepean system traverses Cumberland Plain alluvial terrain and Triassic carbonate-cemented sedimentary deposits, contributing moderate dissolved calcium bicarbonate before Prospect treatment. The Pyrmont City of Sydney inner harbour distribution at 88.5 mg/L and TDS 168.6 mg/L is somewhat elevated compared to soft inner eastern Sydney sub-zones (Kingsford 83.5 mg/L), reflecting the blend routing characteristics of Sydney Water's inner harbour peninsula distribution.
Pyrmont residents can expect occasional moderate limescale on taps and in kettles — descaling every two to three months is typically adequate. Hot water systems benefit from periodic inspection. The elevated lead reading (0.003 mg/L) warrants briefly running the cold tap before use in Pyrmont's converted warehouse apartments and heritage industrial residential conversions. Sydney Water provides water quality information at sydneywater.com.au, with all ADWG health standards consistently met. Pyrmont's dynamic inner harbour residential and corporate community benefits from a safe supply meeting all ADWG standards.
Geology & Source: Supplied by Sydney Water via the Prospect Water Filtration Plant incorporating a moderate Hawkesbury-Nepean blend component — the Pyrmont City of Sydney LGA inner harbour supply carries slightly hard water at 88.5 mg/L with TDS of 168.6 mg/L, reflecting a moderate Hawkesbury-Nepean proportion in the City of Sydney inner harbour distribution at Pyrmont.
