Parkinson Water Hardness & Quality Report (2026)

Seqwater provides bulk water to Parkinson, a suburb within Logan City in Queensland, Australia. Their supply originates from a network of sources, including the Wivenhoe, Somerset, and North Pine reservoirs, all part of the Brisbane River system. Water undergoes treatment at significant facilities like the Mt Crosby Water Treatment Plants (West Bank and East Bank) before being distributed to local retailers such as Logan City Council and Urban Utilities. The Brisbane River catchment itself is vast, drawing water from the Great Dividing Range and its surrounding hills.

The region's water is shaped by its underlying geology. The watershed sits atop Mesozoic sandstones and shales, with Tertiary basalts also present. Tributaries flowing over limestone outcrops contribute dissolved minerals. Specifically, sedimentary basins from the Mesozoic Great Artesian Basin and Cainozoic alluvial formations, which are rich in limestone and dolomite, introduce calcium and magnesium ions. These natural dissolution processes, occurring as water moves across the surface and recharges aquifers, are responsible for the water’s moderate mineral content.

Homeowners in Parkinson might notice slight limescale buildup on faucets and kettle elements over time due to this moderately hard water. Appliances such as coffee makers, dishwashers, and water heaters are particularly susceptible and may benefit from occasional descaling to maintain efficiency and longevity. While you might need slightly more soap or detergent than with very soft water, impacts on skin and hair are usually minimal. Installing a water softener isn't typically necessary at this hardness level, but routine appliance maintenance is a good practice. Recent testing did flag concerns with pH levels, E. coli, and trihalomethanes exceeding guideline limits, though Seqwater utilizes conventional treatment methods to address these.
