What Makes Eagleby's Water Unique?
Local geology and source profile
Eagleby's drinking water is supplied by Logan Water (Logan City Council Water) as water retailer, with bulk supply from Seqwater drawing from Lake Wivenhoe, Lake Somerset, and dominant Lockyer Valley groundwater through the south-east Queensland water grid for the Logan City LGA southern coastal distribution in Queensland. Water hardness in Eagleby is measured at 236 mg/L — classified as very hard, exceeding the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. Eagleby — a working-class residential suburb in the southern Logan City LGA on the Coomera River, adjacent to the Gold Coast City boundary, known for the Eagleby shopping centre and the established residential community of the Logan–Gold Coast boundary corridor — carries very hard supply consistent with the broader Logan City hard supply profile.
Eagleby's elevated hardness reflects the dominant Lockyer Valley groundwater supplement proportion in the southern Logan City SEQ supply blend. Lake Wivenhoe and Somerset contribute moderately soft surface water from Triassic–Jurassic granite terrain of the Great Dividing Range, but Seqwater's heavy supplementation from the Lockyer Valley alluvial aquifer — percolating through mineralised Jurassic–Cretaceous carbonate-cemented Darling Downs formations — elevates the southern Logan coastal distribution to 236 mg/L and TDS 603.2 mg/L. Eagleby's hardness is consistent with the broader Logan City southern coastal supply range (Marsden 280 mg/L, Jimboomba 217 mg/L).
Eagleby residents face significant daily limescale challenges — kettle descaling every one to two weeks is common, shower screens accumulate deposits, and hot water systems require regular inspection. Under Queensland water restrictions, outdoor watering is limited. The elevated lead reading (0.003 mg/L) warrants briefly running the cold tap before use. Logan Water provides water quality data online, with all ADWG health standards consistently met throughout the Logan City distribution network.
Geology & Source: Supplied by Logan Water (Logan City Council) with bulk supply from Seqwater via Lake Wivenhoe and Lake Somerset, supplemented by dominant Lockyer Valley groundwater through the south-east Queensland water grid — the Eagleby Logan City southern coastal supply carries very hard water at 236 mg/L with elevated TDS of 603.2 mg/L, reflecting the dominant Lockyer Valley groundwater proportion in the Logan City southern distribution.
