What the score is
Each suburb gets a score out of 100 built from five indicators. We score each indicator from 0 to 100 using the rules below, multiply it by its weight and add the results. The total falls into the same five bands Healthy Land & Water uses for its Report Card. An A here means what an A means there: very good.
What the score is not
The score does not rate health, and a low one does not mean your tap water is unsafe. Network water across the City of Ipswich is treated to the Australian Drinking Water Guidelines and sampled every month. Every connected tap gets the same water. The score measures what changes from suburb to suburb: whether you are on that network, what the plumbing adds between the meter and the tap, the health of the creek your stormwater reaches, flood exposure and where the wastewater goes. We read the public data with plumbing in mind, to help you decide what, if anything, to do at your place.
The five indicators
| Indicator | Weight | Scoring rule | Source |
|---|---|---|---|
| Drinking water supply | 30% | On the Urban Utilities network: 88. Township on the network with outlying blocks on tanks: 70. Largely tank and bore: 58. Minus 20 if the latest Seqwater zone report shows a health parameter over its guideline. | Seqwater monthly zone report; Urban Utilities annual performance report |
| Plumbing era | 25% | Pre-1960s character housing: 45. 1960s to 1990s: 62. Estates from the 2000s on: 88. Acreage and rural-residential: 60. Minus 6 where historic mine workings sit beneath the suburb. | Housing era from our suburb guides and the ABS 2021 Census; Queensland Government abandoned mines information |
| Local waterways | 25% | The Healthy Land & Water Report Card environmental condition for the catchment the suburb drains to: very good 95, good 80, fair 60, poor 40, very poor 20. | Healthy Land & Water Report Card (annual) |
| Flood exposure | 10% | Suburbs Council’s historical flood mapping shows as reached by the 1974, 2011 or 2022 floods: 45. Others: 85. | Ipswich City Council flood mapping |
| Wastewater | 10% | Sewered: 85. Many properties on septic or on-site treatment systems: 55. | Urban Utilities service area; Council on-site sewerage information |
Where the data comes from, and how often it changes
Monthly. Seqwater publishes a water quality report for the City of Ipswich zone every month, testing 34 or more parameters against the guidelines. Our refresh script reads it and stores the headline figures (hardness, pH, fluoride, chloramine, E. coli and others) next to the guideline values.
Annually. Urban Utilities publishes its Annual Drinking Water Performance Report, Seqwater its Drinking Water Service Annual Report, and Healthy Land & Water its Report Card each December. We copy the catchment grades and notable events from those documents.
Continuously. The Queensland Government’s Water Monitoring Information Portal publishes stream gauge readings for the Bremer River at Walloon, Warrill Creek at Amberley, Purga Creek at Loamside and the Brisbane River at Savages Crossing. The refresh pulls the latest readings from the gauge nearest each suburb.
Quarterly. The refresh runs at the start of each quarter and rebuilds every page. Nothing publishes unless the site passes its checks. Data on this site was last updated 2026-10-01.
