Russell Island is the largest of the southern bay islands and the busiest, with a permanent community, a lot of older housing on small lots and a long history of subdivision. Its drainage reality is genuinely different from the mainland's, and this page says so rather than repeating a mainland promise. Redlands Blocked Drains is a local referral service. We put you in touch with QBCC-licensed local plumbers who work on Russell Island.
Getting a plumber here, honestly
Getting to Russell Island with a work vehicle means a booked vehicle barge from Weinam Creek at Redland Bay, so this is not a job anyone can promise to do today. The passenger ferries do not carry work vehicles, trailers or equipment. Bookings fill up, and services can run late at low water on spring tides.
So here is what we will actually do. We will call you back promptly and tell you honestly whether a local plumber can get to you, and when. Some of the trades who work the islands live on them, which is often the fastest answer and usually the cheapest, because there is no crossing in their costs.
What nobody can honestly offer you is a mainland crew at your door on the strength of a phone call. If a site tells you otherwise, it has not been here.
For current barge bookings and fares, go to the operator at SeaLink. This site states no fare and no timetable, because a state subsidy, an operator discount and a fuel surcharge all apply and the figures move.
Russell Island is unsewered
This is the most important fact on the page, and it changes the diagnosis completely. Redland City Council states that Russell Island is unsewered and serviced by on-site wastewater treatment and septic systems.
There is no council sewer main to blame. Your wastewater goes to an on-site septic or treatment system on your own block, so a backing-up drain here is almost always a problem on your side of the fence, and the fix is a different job from a mainland sewer blockage. The council's three-step test, the inspection opening diagnosis and the reimbursement process all assume a council main, and none of them apply to you.
It is worth knowing that this is structural rather than temporary. The council lists seven wastewater treatment plants, at Capalaba, Cleveland, Dunwich, Mount Cotton, Point Lookout, Thorneside and Victoria Point. There is none on the southern bay islands. This site publishes no cost or date for island sewerage, because the figures that circulate are neither current nor a council commitment.
What actually goes wrong here
- The tank is full. The cheapest cause to rule out, and a pump out is routine maintenance rather than a repair. Pump out services operate on the island, and for a full tank that is the call to make.
- The disposal area is saturated. After a wet week the ground simply cannot take any more and the system backs up from the far end. Wet, smelly or unusually green ground over the trenches or irrigation field is the tell.
- A pump, blower or float has failed. On an aerated or advanced treatment system this stops the process. Many have an alarm, and many alarms have been silenced at some point.
- Roots or a collapse in the line to the tank. Ordinary drain work, and a camera and jetter handle it the same way as anywhere.
- Too much water at once, or bleach and heavy disinfectant in quantity, both of which a biological system reacts badly to.
The septic and on-site wastewater page covers the difference between a septic tank and a treatment system, and what each one needs.
What the rules require
On-site systems in Redland City must meet plumbing, health and environmental standards, and council approval applies to installing or altering one. If someone tells you a particular type of system is mandatory on the island, ask them to show you the council document, because this site has not been able to verify that and will not repeat it.
Plumbing and drainage work in Queensland requires a QBCC licence at any value. Ask for the licence number and check it on the QBCC register before signing.
What it costs
Clearing a blocked line into the tank is ordinary drain work and sits in the usual $150 to $400 range, with a camera at $249 to $600 and jetting bundled at $350 to $900. On-site wastewater work, pump outs, pump and blower repairs and disposal area remediation, is priced separately. If a mainland plumber crosses, the barge booking and most of a day of travel go into the price, and they will say so. An island-based trade often works out cheaper. The cost guide sets out the ranges.
Frequently asked questions
How long will it take for someone to get here?
The callback is prompt. The visit depends on the next available vehicle barge and on whether the plumber is island-based or crossing. We will tell you which, rather than guessing at a time.
Do mainland plumbers really come out here?
Yes, with a booked vehicle barge and a day set aside for it. For a planned job that works well. For something urgent, an island-based trade is usually the shorter path.
My drain is backing up. Is it the council's main?
No. Russell Island has no council sewer main. The whole system, including the tank and the disposal area, is on your block and is yours.
Should I just get a pump out?
If the tank is full, that is the fix and it is the cheapest call you can make. If the tank is not full, pumping it out will not solve anything, so it is worth having someone look at what the system is actually doing.
Can a jetter and camera get here at all?
They can, on the vehicle barge. That is why island work is planned rather than immediate, and why it is worth describing the problem fully when you send the form.
