Macleay Island has the second-largest community of the southern bay islands, with a small village centre, a steady year-round population and a mix of older cottages and newer builds on compact blocks. Like its neighbours, it runs entirely on on-site wastewater systems. Redlands Blocked Drains is a local referral service. We put you in touch with QBCC-licensed local plumbers who work on Macleay Island.
Getting a plumber here, honestly
Getting to Macleay 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, and services can run late at low water on spring tides.
What we will do is 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.
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.
Macleay Island is unsewered
Redland City Council states that Macleay Island is unsewered and serviced by on-site wastewater septic and treatment 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 its sewer reimbursement process all assume a council main, and none of them apply here.
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, so the unsewered status is structural rather than a gap about to close. This site publishes no cost or date for island sewerage.
What actually goes wrong here
- A full tank. The cheapest cause to rule out, and a pump out is maintenance rather than a repair. Pump out services operate on the island.
- A saturated disposal area. After a wet week the ground 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 sign.
- A failed pump, blower or float switch on an aerated or advanced treatment system, which stops the process. Check whether an alarm has been silenced.
- Roots or a collapse in the line to the tank, which is ordinary drain work for a camera and a jetter.
- Overload or chemicals. Too much water at once, or bleach and disinfectant in quantity, both of which a biological system reacts badly to.
The septic and on-site wastewater page covers the difference between the system types and what each 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. This site will not tell you a specific system type is mandatory on the island, because that claim is not verified on any council page we could find.
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 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 is priced separately. If a mainland plumber crosses, the barge booking and most of a day of travel go into the price, and an island-based trade often works out cheaper. The cost guide has the ranges.
Frequently asked questions
When can someone actually get here?
The callback is prompt. The visit depends on the next available vehicle barge, and on whether the plumber lives on the island or has to cross. We will tell you which rather than guessing.
Is my blocked drain the council's problem?
No. Macleay Island has no council sewer main. The tank, the pump and the disposal area are all on your block and all yours.
Can I get a camera and jetter out here?
Yes, on the vehicle barge. It makes island work a planned job, which is why a full description of the problem helps when you send the form.
The ground over my trenches is always wet. What does that mean?
Usually that the disposal area is struggling, either because it is saturated, clogged or undersized for current use. That is a service and remediation question rather than a drain clear.
Who services an aerated treatment system?
Servicing is usually arranged with the manufacturer or an authorised servicing agent under a service contract, separate from a plumber's call-out.
