How can I tell if my Jimboomba home is on septic?

Look inside the electricity meter box: Logan City Council places an identification sticker there for properties with an on-site sewerage facility. No sticker and still unsure? Ask Council.

Is the water in my trickle feed tank safe to drink?

Logan Water treats the town water it supplies, but says once it mixes with roof water in the tank it may not meet health limits. It recommends filtering out bacteria or boiling water for drinking and cooking.

Plumbers in Jimboomba: treatment plants, tanks and Logan Water

Plumbers in Jimboomba Sewer, septic or tank?

Jimboomba is in the City of Logan, where Council runs the water and sewer. Logan's rural land sits on the city's southern, western and eastern edges, and Council says any property not connected to its sewer needs its own treatment system. So the first question here is what your block is on. We match you with a licence-checked plumber who specialises in that set-up.

Jimboomba facts for a plumbing job

Houses, mostly mortgaged

96.7% of the suburb's occupied homes were separate houses at the 2021 Census. 61.7% were owned with a mortgage and 13.5% rented.

Round Mountain water

Logan Water lists Jimboomba as a main suburb of its Round Mountain supply zone, with parts in the Travis Road and Woodhill zones.

Lowest hardness in Logan's report

Those three zones make up Logan South, which averaged 50.53 mg/L total hardness in 2024/25 (range 32.7 to 130), the lowest of Logan's reported zones.

City of Logan

Jimboomba is in Logan City Council's area. Logan Water, not Urban Utilities, owns the mains.

If your block has a treatment plant

An on-site system has to sit inside your boundary, within its approved land application area, and Council makes owners and tenants responsible for maintaining it. Queensland law requires an aerobic wastewater treatment plant to be serviced every 3 months, and an aerobic sand filter every year, by a licensed service agent.

Not sure what you've got? Since October 2020, Council officers have been putting an identification sticker in the electricity meter box of each Logan property with an on-site system. Scanning it shows the system's service history. Our septic systems page covers what a plumber checks.

Tanks with a trickle feed

Where Logan's network can't meet every user's demand, some homes have trickle feed or mixed demand systems. Town water trickles into the rainwater tank through a restricted valve, at about 2 litres per minute.

Because roof water mixes in, Logan Water says tank water may not meet the drinking water guidelines' health limits. For drinking and food preparation it recommends a filter that removes bacteria, or boiling, and keeping the tank clean is the owner's job. See rainwater tanks and tank pumps.

Homes on the sewer

On a sewered block, Logan Water's part ends at the first inspection opening on your property connection, and the drain upstream is yours. Mention you're in Logan when you book, because the plumber has to alert Logan Water early if a blockage looks like Council's. Our Logan page explains how reimbursement works.

What we would do

Before booking, work out three things: sewer or on-site system, town water or tank, and whether there's a sticker in the meter box. A plumber who services treatment plants is a different specialist from a drainer, and a tank pump fault is different again. Getting the match right first time saves a second call-out.
