One water company, two dividing lines
Urban Utilities supplies water and wastewater services across Brisbane City Council's area. Its bill arrives separately from your Council rates, and its pipe rules are the ones that apply here.
For drinking water, the line is the meter: the meter and the pipes back to the main are Urban Utilities', and everything from the meter to the house is the owner's. For sewage, the line is the sewer connection point. Urban Utilities says that point can sit outside the boundary, under the council footpath or on common property, and the pipe up to it is still yours.
Stormwater changes hands at the boundary. Brisbane City Council maintains the drains beyond it; on your block, you keep the pipes and the outlet to the point of discharge working.
Just outside Brisbane City
Some of our Brisbane suburb pages cover neighbouring council areas. Ipswich is also an Urban Utilities area. Homes in the Moreton Bay council area are on Unitywater, which has its own rules. Anywhere else, the water company on your bill sets them. Our sewer pipe guide compares the companies we've checked.
What's different about plumbing in Brisbane
A city of units as well as houses
In Brisbane City Council's area at the 2021 Census, 25.6% of occupied homes were flats or apartments and 62.6% separate houses. Across Greater Brisbane, apartments were 14.7%. In a complex, your meter may sit beside your unit or in a shared cabinet.
Older houses may lack a gully
Urban Utilities says homes built before 1976 may have no overflow relief gully unless they've been renovated. That grated outlet, usually near the laundry, lets a blocked sewer spill in the yard instead of inside.
Water on the hard side
Urban Utilities calls South East Queensland's water hard to moderately hard. For the supply serving Brisbane and Ipswich, its 2024-25 mean was 120 mg/L, under the 200 mg/L guideline. Hard water can scale up a hot water system.
Storms, not frost
The Bureau's Brisbane station hasn't recorded anything colder than 2.6°C since it opened in 1999. Archerfield, on the south side, averages 2.4 days a year at 2°C or below. Rain is the bigger test. Archerfield's wettest day on record brought 343.7 mm, and storm water getting into the sewer can push sewage out of low gullies.
A blocked sewer: who pays
If the blockage is in your pipe, you pay. If a plumber finds it in Urban Utilities' pipe, you settle the plumber's invoice first and can then ask Urban Utilities to consider a claim for reasonable costs. The claim is yours to make: Urban Utilities says a plumber can't apply for you.
Digging to find the problem without its approval stays at your cost. If an inspection opening or gully is overflowing, or neighbours have the same trouble, ring Urban Utilities' 24/7 faults line first. Our Brisbane blocked drains page has the steps.
The four kinds of plumbing work
Brisbane City Council sorts plumbing jobs into four kinds. Small unregulated jobs need no licence. Minor work, such as clearing a blocked drain or fixing a broken pipe, needs a licensed plumber but no permit. Notifiable work, like new fixtures in a bathroom or kitchen renovation, is reported by the plumber to the QBCC on a Form 4. Anything else needs a Council plumbing permit.
Notifiable work is registered within 10 business days of the invoice, and a copy should reach you within 20 business days of that. Ask which kind your job is before it starts.
Checking a Brisbane plumber's licence
The QBCC licenses plumbers and drainers in Queensland. Search its licensee register and its occupational plumber and drainer register through myQBCC, for both the business and the person doing the work. Our licence check guide shows what to look for. Gas fitters hold a separate Queensland gas work licence.

Go straight to the job: hot water, blocked drains, leak detection, pipe relining, gas fitting, backflow testing, commercial plumbing or an emergency plumber.
Suburb pages, from Indooroopilly to Wynnum, add the local detail for each area.
What we would do
Ask two questions first. Is the problem on your side of the meter or the sewer connection point? And is anything overflowing outside, or affecting the neighbours too? If sewage is coming up in the street, ring Urban Utilities before you book anyone. Otherwise pick a licensed plumber who does your kind of job every week, and keep the paid invoice: if the fault turns out to be Urban Utilities', your claim rests on it.
