Blocked Drains Buderim
Buderim reported more call-outs for wastewater blockages than any other suburb in the Unitywater network in 2024/25. We received 237 in one year, which is way more than any other suburb on the list. The single biggest culprit identified is tree roots entering the pipes. What we do is clear the blockage then camera the line of your pipework to pinpoint where the roots are entering. Then we can seal up that point of entry so you don't have the same problem time and again.

Why Buderim Tops the List for Blocked Drains
Unitywater's figures show Buderim was the highest on its 2024/25 blockage table, with 237 call-outs on the suburb's wastewater network. Coming in second and third place were Caboolture and Nambour respectively. Tree roots account for about one in five known blockages in the utility's network. These are the highest among three other of Unitywater's served suburbs: Clontarf, Caboolture, and Buderim, listed above among the most impacted.
These numbers reflect only the blockages on the public side of the wastewater network. Those call-outs on private property which were the responsibility of a plumber are not recorded in these numbers and will therefore be higher overall.
What's Actually Causing the Blockages
Ageing pipework
Buderim is one of the older suburbs on the Sunshine Coast, so most of the underground infrastructures are quite old. Early on, many sewer main lines were built using short 300mm lengths of clay pipe with a joint at approximately every 300mm.
Moving Soil
During the wet, the soil soaks and this in turn leads to swelling. However, it shrinks in drier times. When sitting on sloping blocks, movement provides added stress on pipe joints.
Trees that made the suburb, and problems underground
Buderim's lush roads and established gardens were some of the suburb's drawcards, but those same trees cause headaches beneath the surface. Roots always grow towards water and what easier destination than a warm steam line that can be emitting fumes through a crack as fine as a hair. Some of the main perpetrators around this area are fig trees, bottlebrush and paperbark. A tendril can grow into a joint, then split to cause a real blockage within weeks.
Everyday causes
In addition to the root causes, we also experience the normal offenders. Cooking oil sets to form hardened wax in kitchen pipes, hairs bind up into a wad in the bathroom drains. Wipes, sanitary items, even cotton buds, do not break down and are therefore quickly caught in and can help accelerate blockage in already root-clogged pipes.
The overflow relief gully is your friend
The circular grate near your bathroom or laundry wall is specifically designed for the sewerage to escape if the line becomes blocked. Waste then rises in the pit instead of backing up through the shower. So if you see it is working overtime; run no water from any fixtures inside the house, and call a plumber. Do not pave it in, plant garden beds around it, or place pots on it. Doing so will direct overflow to the next lowest available point, which may be inside the house. Acting fast here stops a minor overflow turning into water damage.
Warning Signs Worth Learning
Most drain blockages give some warning first. A problem caught early can usually lead to a simple same-day clearing service rather than an emergency call-out.
You may have noticed:
- Bubbling toilets or plug holes in one fixture when you run another, such as a sink.
- Two or more drains in the house running more slowly than they should be.
- Unusually low or high toilet bowl levels, or bubble action after a flush.
- Smelly sewage in the garden, laundry or bathroom.
- A patch of excessively green grass running across your lawn, tracing the line of your sewer pipe.
- The relief gully (often situated near the street outside your house) begins to leak even when the garden isn't wet.
Left to sit, a nasty blockage can result in sewerage bursting through the lowest floor level of your home.

How We Clear a Blocked Drain in Buderim
- Examine and pinpoint: we first work out if it is a sewer or a stormwater drain, and if the obstruction is within the kitchen branch line or the main line. Then we select appropriate equipment.
- Unblock the drain: High-pressure jetting, using a purpose-made high-pressure water jetter, cuts the roots or grease causing blockage. It scours the pipe to its original capacity through focused jet blasting. For internal lines, an electric drain machine used with a cutting head works well. Where there is a heavy density of roots, a partially cleared root mat will often grow very quickly.
- Survey line with a camera: CCTV drain cameras are sent through the clear line to record footage using our latest camera tech. CCTV pipe inspections like this one turn guesswork into a clear diagnosis. This will clarify where the roots are entering the pipe: without this step property owners will experience repeated blockages.
- Confirm cause and pipe condition: The recorded CCTV film reveals broken joints, cracks and the root penetration points in the line. It shows not just where it is blocked, but why.
- Offer solutions: We provide and price two or more possible repair solutions, according to CCTV results. Options include periodic clearing, repair by sectional patches, or replacement through re-lining or excavation. Property owners are free to select one based on budget and desired durability of repair.
Permanent Fixes for Recurring Blockages
Cutting the roots where they protruded was, at best, a short-term fix as the severed roots will simply regrow again. In this situation, where the drain gets blocked regularly, it's time to get that drain fixed. There's a proper fix for this type of problem as well.
Pipe relining
Trenchless pipe relining means a resin liner is fed into the old damaged pipe and cured in position as a new, smooth, jointless pipe inside the old one. This restores drain pipes without a single trench dug. This seals any joints and any cracks that the tree roots were utilising to enter the pipe in one go along the entire section. Unitywater applies this same relining technique to parts of its water network. For established gardens and driveways the benefit is easy to see – no digging, no garden dug up, most drain relining projects are completed within a day.
Tree roots also tend to stay away from future drain relining, as there are no joints left for them to penetrate. As a form of pipe restoration, trenchless repairs are also generally quicker and less disruptive for pipe repairs and pipe renewals when compared to replacement pipework.
Sectional patches
Sometimes the camera is only showing that one spot (like a single joint) was damaged. Then we use a patch liner only at that spot; a bit cheaper than lining the whole pipe! Often a wise option for long pipes if only one part is affected.
Excavation
For some pipes that are completely collapsed or too badly out of grade to be relined, we state that plainly in the footage. We then quote the dig in which we propose this takes place. On a sloping block, we design the excavation so that the smallest impact is made on the yard.
Whose Responsibility Is It: Yours or Unitywater's?
The cut-off point is easy. Any drains within your property boundary until the connection point are yours. Unitywater looks after any public drains from the connection point outwards.
You can view our network location viewer before digging and when planning new gardens. Our camera footage can put arguments to rest. If a fault is found to be on Unitywater's side, we produce and confirm a video identifying its position to give you an accurate copy to pass to us.
Preventing Blockages: A Checklist for Buderim Homes
- Check Unitywater's mapping tool before planting anything near a pipe run, and plant more shallow-rooted species over figs, bottlebrushes or paperbarks near the house.
- Wipe pans before washing and bin cooking oil instead of flushing it down the sink.
- Install a hair catcher over the shower and bath drains.
- Think of the three Ps: pee, poo and toilet paper. Even flushable wipes can cause blockages.
- Keep your overflow relief gully clear of paving, pots and garden beds.
- Book an annual scheduled camera inspection, especially in an older street with large trees near you, or before purchasing a property.
- Clear gutters and grates before the storm season and have any sluggish stormwater pipes jetted before the first summer storm.
Simple Checks Before You Call a Plumber
For minor surface debris, pouring a tablespoon of baking soda and vinegar down the drain, then flushing with hot water, often alleviates the problem.
We'd stay away from chemical drain cleaners. Over time these will corrode your plumbing. They will rarely fix anything if the obstruction is deeper in the pipe where the chemicals are no longer potent enough to work.
If you find that the issue is persistent, or if more than one drain in your household is slow-moving, it is time to stop the DIY treatment plan. Schedule professional blocked drain cleaning instead. Any plumbing work beyond that point is best left to a licensed technician.
The Technology Behind the Fix
Most jobs around here require a combination of advanced techniques for diagnosing properly, rather than just symptom relief.
Our advanced CCTV cameras crawl their way through the entire length of your pipe, filming cracks, the extent of root invasion and the condition of your drain. This reveals detail at a depth way beyond what any excavation could easily show.
Water jet technology gets the job done. Our powerful high-pressure jetters use focused jets of water to blast away any grease build-up, debris and root intrusion. There's none of the abrasive damage that conventional machinery sometimes imposes.
Hydro and Vacuum Excavation
Our plumbing technicians carry both hydro and vacuum excavation equipment. This lets us expose sections of pipework exactly where needed, without the disruptive effort of a large-scale trench.
Water pressure softens the ground, and a vacuum unit removes the loose soil. This protects nearby plants and paved areas while making access possible.
Leak Detection on Board
We carry leak detection tools on every job to catch hidden leaks near the blocked section before they become a bigger problem.
Protecting your Stormwater System: More than just clogged sewer drains, blockages also affect your stormwater drainage.
A failure in drainage can result in overflow onto the property during heavy rainfall. This leads to far more extensive, costly and time-consuming property damage including to structures as well as potential loss of use and rental income. Catching the problem earlier through regular pipe cleaning and checks before and after the wet season cuts the risk of a big bill later.
Property Managers and Landlords
The drain blockage risks for rental properties are higher than owner-occupied properties due to the greater usage.
Booking regular plumbing maintenance such as routine inspection and professional pipe cleaning can cut the number of emergency plumber calls each year. This saves you real money and hassle.
A few habits worth building into a routine for tenanted properties:
- Regular inspections between tenancy arrangements, especially on older rental properties.
- Kitchen and bathroom drain filters to catch foreign objects early.
- Basic tenant guidance on what shouldn't go down the drain.
- Detailed property files that flag properties prone to chronic blockages, since that can point to a structural issue.
- Annual proactive maintenance checks, particularly before and after the wet weather season.
These simple drainage solutions can make all the difference.
Frequently Asked Questions
Can you come out to Buderim today?
In almost all cases, we carry out work in Buderim and can respond the same day, generally within the morning. Typically, most morning call-outs are resolved within the same day, and out-of-hours call-outs for emergency issues like sewage backflow will be resolved immediately.
Is my blockage tree roots?
It's very common for blockages in Buderim to be caused by tree roots. This is especially true in older streets and suburbs where tree growth around the pipes is extensive or where clay pipes have a history of becoming affected. Our video inspection camera will identify these quickly and clearly indicate their entry point.
How do I get rid of the tree roots?
Root foaming treatments only slow their regrowth for a while by poisoning them. The actual opening they use to get into the pipes will stay, and roots will find their way back in.
While tree removal is often an option, there are often neighbouring trees which may assume their feeding roles in future, or you simply might have attachments to them! A reline or patch will close off the actual pipe entry once the roots are cleared, removing the ability to enter regardless.
Won't a pressure washer damage old clay pipes?
The 'pressure' in our pressure washer refers to a finely-tuned water stream, and when it is handled correctly for older clay pipes, no actual damage occurs.
We will check your pipes' own condition to make sure the right cleaning pressure and jet head are used, which is often far less invasive than manual augering techniques.
What is the average cost to clear a blocked drain in Buderim?
Every situation is unique; blockages can occur under the patio, at the boundary of a property, or internally in kitchens and bathrooms. Our technicians price each job at the site once a clear diagnosis has been established during the pipe camera inspection. We provide a fixed quote for both the immediate clear as well as any remedial repair required (such as relining).
How many times can we afford to clear this drain?
If you have had this drain cleared multiple times over the past few years with similar results then it indicates a problem that hasn't been addressed. The only long-term solution involves identifying the source of repeated root entry and any pipe defects.
A full camera survey, identifying every entry point, will provide a diagnosis. From there, we propose relining to offer the only true and long-term fix that avoids excavation.
