Water quality in
Goodna.

Goodna is on the Urban Utilities drinking water network, supplied from Seqwater’s Mt Crosby treatment plants on the Brisbane River. Stormwater from Goodna runs to Woogaroo Creek, Goodna Creek and the Brisbane River, in the Lower Brisbane River catchment, which the 2025 Report Card rated poor. Below: what that means at the tap, in the hot water system and in the creek, from the government figures.

WHAT’S IN THE WATER · GOODNA

Where Goodna’s
tap water comes from.

Goodna is on the Urban Utilities drinking water network, supplied from Seqwater’s Mt Crosby treatment plants on the Brisbane River. The chain is the same for every connected home in the city: water released from Wivenhoe Dam travels down the Mid Brisbane River to Mt Crosby, where Seqwater’s East Bank and West Bank plants treat it, and Urban Utilities pumps it through its Ipswich reservoirs to your meter. Seqwater publishes a report on the City of Ipswich zone every month; the headline figures are in the table below.

Two things are added on purpose. The disinfectant is chloramine rather than plain chlorine, which holds a residual over the long mains out to Goodna and is the reason a standard carbon jug does less than people expect. Fluoride is dosed to a target of 0.8 mg/L under Queensland law. Both matter to fish keepers, who need to neutralise the chloramine, and to anyone on home dialysis, who should talk to their unit about filtration.

Mineral spike after heavy rain, 20 November 2024. Treated water from the Mt Crosby plants recorded total dissolved solids of 700 and 730 mg/L (guideline 600), chloride of 270 and 300 mg/L (guideline 250) and hardness of 250 mg/L (guideline 200) after a significant rainfall event pushed natural mineral concentrations up in the Mid Brisbane River. Five aesthetic guideline exceedances, no health exceedance. Seqwater Drinking Water Service Annual Report 2024–25

How hard is the water in Goodna?

Network water here is moderately hard: 80–115 mg/L as CaCO₃, against an aesthetic guideline of 200 mg/L, and it spiked to 250 mg/L in November 2024 after heavy rain washed minerals into the Mid Brisbane River. In practice that means scale on kettles, shower screens and, most expensively, on hot water elements and heat exchangers. It is why a hot water system in Goodna benefits from scale protection on its feed, and why a whole-house softener is usually more than the water justifies. Hot water systems in Goodna ↗

The pH is going up

Seqwater is lifting the pH of water leaving Mt Crosby from about 7.8 to a target of 8.4 from mid-August 2026, to extend disinfection in warm months, raise alkalinity and reduce corrosion in the network. The change covers Brisbane, Ipswich, Logan, Moreton Bay and parts of the Scenic Rim. For Goodna homes that is good news for copper pipes and brass fittings, which corrode less in slightly more alkaline water, and a small nudge towards scale in hot water systems. Fish keepers will want to re-check their tank water after the change.

What the pipes in Goodna add

Most of Goodna was plumbed before copper became standard, so galvanised steel water pipes are still in service under a lot of houses here. They corrode from the inside, which is where brown water first thing in the morning comes from, and old brass fittings and solder can add trace lead to water that has sat in the pipe overnight. The Australian Government’s health advice is simple and free: run the tap for about 30 seconds after it has been unused for several hours before you fill a kettle. Beyond that, the question is how much of a failing run to replace, and that is a plumbing conversation rather than a water one.

The 2021 Census counted 3,603 private dwellings in Goodna, 82% of them separate houses and 17% townhouses or apartments, where the water service is shared and the body corporate owns the pipework up to your lot. About 48% of households rent, so for most homes a water problem goes to the property manager first, and we deal with them directly.

Woogaroo Creek: where Goodna’s water goes

The tidal Brisbane River below Mt Crosby Weir, and the creeks that run into it from the eastern side of Ipswich: Woogaroo, Six Mile, Goodna and Opossum creeks. Greater Springfield, Goodna, Redbank Plains and the riverside acreage suburbs drain here. Goodna’s stormwater reaches Woogaroo Creek, Goodna Creek and the Brisbane River.

Healthy Land & Water rated the Lower Brisbane River catchment “Poor” for environmental condition in the 2025 Report Card, with social and economic benefits rated very high. The 2025 Report Card notes nitrogen concentrations rising in the Brisbane estuary and a general decline in catchment condition across the region since 2021. 2025 Report Card ↗

Low-lying parts of Goodna were reached by the 2011 and 2022 floods, and Council’s historical flood mapping shows how far. Floodwater is untreated river and creek water carrying sewage, fuel and silt, and what it leaves in drains, gullies and rainwater tanks is the water quality problem that lasts. A tank that went under needs emptying and cleaning; a hot water system that went under needs checking before it is used. Council flood mapping ↗

Where the wastewater goes

Goodna is sewered. Wastewater goes to one of Urban Utilities’ four Ipswich treatment plants, at Bundamba, Goodna, Carole Park and Rosewood, and treated water is released to the rivers under Queensland environmental authorities. What stays yours is the sewer drain under the house and out to the connection point, which is where blockages, root intrusion and overflows happen. Sewer drain repairs in Goodna ↗

GOODNA WATER QUESTIONS

Straight answers.
Awkward ones too.

Is the tap water in Goodna safe to drink?

Yes. Network water in Goodna is treated at Mt Crosby, chloraminated and fluoridated, and sampled every month by Seqwater and Urban Utilities against the Australian Drinking Water Guidelines. The things people notice, chlorine taste, scale, the odd brown tap after mains work, are aesthetic, not health, issues.

Is Goodna water hard or soft?

Moderately hard. Urban Utilities describes South East Queensland water as hard to moderately hard, and zones supplied from Mt Crosby have reported around 80 to 115 mg/L as calcium carbonate, against a guideline of 200 mg/L. It briefly reached 250 mg/L in November 2024 after heavy rain in the Mid Brisbane River. In Goodna that shows up as scale on hot water elements and shower screens rather than anything you would taste.

Does Goodna tap water contain fluoride?

Yes. Seqwater adds fluoride at Mt Crosby to a target of 0.8 mg/L, within a range of 0.6 to 1.0 mg/L, as required under the Fluoridation of Public Water Supplies Act 2008 (Qld). The health guideline is 1.5 mg/L. Every council on the South East Queensland Water Grid, Ipswich included, receives fluoridated water.

Why does my water in Goodna look brown, cloudy or milky?

Milky water that clears from the bottom of the glass up is air, and harmless. Brown or yellow water after Urban Utilities has worked on the mains, or after a burst nearby, is sediment stirred up in the pipes: run an outside tap until it clears and avoid the washing machine until it does. In older Goodna homes, brown water first thing in the morning that clears after a minute is usually your own galvanised pipes shedding rust, which is a replacement conversation rather than a utility one. If it does not clear, Urban Utilities takes water quality reports on 13 23 64.

Is Woogaroo Creek safe to swim or fish in?

The Lower Brisbane River catchment was rated poor for environmental condition in the 2025 Healthy Land & Water Report Card. The standing advice for any natural waterway in South East Queensland is to stay out of it for at least three days after heavy rain, when stormwater carries the most bacteria and sediment, and to treat any fish you catch as coming from an urban river.

Do I need a water filter in Goodna?

Not for safety. A chloramine-rated carbon filter, if taste is the complaint. In a character home, a certified point-of-use filter at the kitchen tap is the sensible addition. We fit filters, and we will tell you when you do not need one.

My Goodna home has flooded before. Does that affect the water now?

Not the water Urban Utilities delivers, which is treated regardless. What floods leave behind is silt in your own drains, gullies and sometimes the service line, and a rainwater tank that has been under floodwater is contaminated until it is emptied and cleaned. If drainage has been sluggish since a flood, or a tank went under, say so when you enquire: it changes where we start.
