What Makes Kingswood Park's Water Unique?
Local geology and source profile
Kingswood Park's drinking water is supplied by Sydney Water, treated at the Prospect Water Filtration Plant drawing predominantly from Warragamba Dam (Nepean River system) for the Penrith City LGA outer western Sydney distribution in New South Wales. Water hardness in Kingswood Park is measured at 58.5 mg/L — classified as soft — well below the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. Kingswood Park — a residential suburb in the outer western Sydney Penrith LGA adjacent to Kingswood and Penrith, known for the Western Sydney University Penrith (Kingswood) campus, the Penrith outer western Sydney residential community, the Great Western Highway corridor, and the established suburban character of the Penrith-Kingswood outer western Sydney district — receives predominantly soft supply from the Prospect Water Filtration Plant distribution.
Kingswood Park's soft supply reflects a predominantly Warragamba Dam contribution with minimal Hawkesbury-Nepean blending at the outer western Penrith Prospect distribution sub-zone. Warragamba Dam collects rainfall from the Blue Mountains sandstone plateau and Kanangra–Boyd granite uplands — chemically resistant terrain contributing negligible dissolved minerals. Despite Kingswood Park's proximity to the Hawkesbury-Nepean River system, the Prospect distribution sub-zone for this area is predominantly Warragamba-supplied at 58.5 mg/L and TDS 103.7 mg/L — reflecting the Prospect filtration blend and distribution routing for the outer western Penrith supply corridor.
Kingswood Park residents enjoy low to moderate limescale accumulation on taps and in kettles — descaling every two to three months is typically adequate. Hot water systems accumulate minimal scale. The low lead reading (0.002 mg/L) is excellent. Sydney Water provides water quality information at sydneywater.com.au, with all ADWG health standards consistently met. Kingswood Park's Western Sydney University campus community and the Penrith outer western Sydney residential precinct benefit from this soft supply meeting all ADWG standards.
Geology & Source: Supplied by Sydney Water via the Prospect Water Filtration Plant drawing predominantly from Warragamba Dam — the Kingswood Park Penrith outer western Sydney supply carries soft water at 58.5 mg/L with low TDS of 103.7 mg/L, reflecting a predominantly Warragamba-dominant supply with minimal Hawkesbury-Nepean component in the outer western Penrith City LGA distribution sub-zone.
