Why Norwood and Burnside Homes Have the Worst Tree Root Drain Problems in Adelaide
The leafy streets of Norwood and Burnside are some of the most beautiful in Adelaide. Massive elm trees arch over the roads. Century-old figs shade character homes. Plane trees line the avenues. It is exactly the kind of established, prestigious neighbourhood that people pay a premium to live in.
But underground, those beautiful trees are waging a constant war against your drains. And in Norwood and Burnside, the drains are leaking.
As Adelaide plumbers who service these suburbs regularly, we can say without hesitation that Norwood and Burnside have the worst tree root drain problems in Adelaide. It is not even close. The combination of massive established trees, original clay pipes from the early 1900s, and council-protected street trees creates a perfect storm that no other Adelaide suburb can match.
This guide explains why these suburbs are so badly affected, what happens when roots invade your drains, and what solutions actually work when you cannot remove the trees causing the problem.
The Perfect Storm: Old Pipes Meet Massive Trees
Tree root problems in drains happen everywhere in Adelaide. But Norwood and Burnside have a unique combination of factors that make the problem far worse than anywhere else.
Some of Adelaide’s Oldest Residential Streets
Norwood and Burnside were among Adelaide’s first suburban developments. Many homes date from the 1900s through to the 1940s, with some even older. These are not just old houses. They have old plumbing. The original clay and earthenware sewer pipes installed when these homes were built are now 80 to 120 years old.
Clay pipes were installed in short sections, typically 300mm to 600mm long, joined together with cement mortar. Over a century of ground movement, settlement and minor earthquakes have shifted these pipes. The mortar joints have cracked, separated and crumbled. Every joint is now a potential entry point for tree roots.
Massive Established Trees With Enormous Root Systems
The trees in Norwood and Burnside are not garden shrubs. They are massive specimens that have been growing for 50, 80, or even 100 years or more. English elms, Moreton Bay figs, London plane trees, and various eucalyptus species dominate these streets. Their root systems extend 15 to 25 metres from the trunk, sometimes further.
On a typical Norwood or Burnside block, there is nowhere that is out of reach of tree roots. Your sewer line runs through the root zone of multiple trees, both on your property and on neighbouring properties. Street trees planted in the verge send roots under the footpath and into front yards. The trees are everywhere, and so are their roots.
Council-Protected Trees You Cannot Remove.
Here is the factor that really sets Norwood and Burnside apart. Many of the trees causingdrainagen problems are protected. Significant trees on private property require council approval to remove, and that approval is often refused. Street trees belong to the council and cannot be removed by residents at all.
In most Adelaide suburbs, if a tree is destroying your drains, you can remove it and solve the problem. In Norwood and Burnside, you often cannot. The elm tree sending roots through your sewer line might be heritage-listed. The fig tree blocking your stormwater might be a council street tree. You have to find solutions that work around the trees because removing them is not an option.
What Tree Roots Do to Your Drains
Tree roots are attracted to the moisture and nutrients inside sewer and drainage pipes. They can detect the moisture vapour escaping from even tiny cracks, and they grow toward it. Once they find an entry point, they exploit it.
Roots enter through joints and crack – The deteriorating mortar joints in old clay pipes are like open doors. Fine root tendrils find their way through gaps that are only millimetres wide. Once inside, they have access to a perfect growing environment.
They grow rapidly inside the pipe – The inside of a sewer pipe is paradise for roots. Constant moisture, nutrients from waste, and protection from the elements. Roots that enter as thin threads can grow into thick masses within months.
They catch waste and cause blockages – As roots fill the pipe, they trap toilet paper, grease and other waste. The flow slows, then stops. You get a blocked drain that backs up into the house.
They expand and crack the pipe further – Growing roots exert pressure on the pipe walls. Cracks widen. Joints separate further. What started as a small entry point becomes a gaping hole. In severe cases, roots can completely crush and collapse old clay pipes.
In Norwood and Burnside, we regularly find pipes that are more root than pipe. The clay has crumbled away, and the only thing giving the pipe any structure is the mass of roots inside it.
Tree Roots Blocking Your Norwood or Burnside Drains?

The Recurring Blockage Cycle
Many Norwood and Burnside homeowners are stuck in a frustrating cycle. The drain blocks. A plumber clears it. Everything works for three months, six months, maybe a year. Then it blocks again. The same roots grow back through the same entry points, and the process repeats.
This happens because clearing roots without sealing the entry points is only a temporary fix. The roots are gone, but the cracks and gaps in the pipe remain. As long as those entry points exist, roots will find their way back in.
Some homeowners have been paying for root clearing every six to twelve months for years. They spend $300 to $500 each time, adding up to thousands of dollars over a decade, with no permanent solution. The trees keep growing, the roots keep coming back, and the cycle continues.
Breaking this cycle requires either removing the trees, which is often not possible in these suburbs, or permanently sealing the pipes so roots cannot re-enter.
Additional Plumbing Challenges in These Suburbs
Tree roots are the headline problem, but Norwood and Burnside homes face other plumbing challenges related to their age and character.
Corroded Galvanised Water Pipes
Homes from the early 1900s through to the 1960s typically have galvanised steel water supply pipes. After 60 to 100 years of Adelaide’s hard water flowing through them, these pipes are severely corroded inside. Rust buildup narrows the internal diameter, reducing water pressure throughout the house. Eventually, they develop pinhole leaks or fail.
Low water pressure is one of the most common complaints we hear from Norwood and Burnside homeowners. The old galvanised pipes simply cannot deliver the flow that modern fixtures and appliances need.
Renovated Homes With Mixed Plumbing
Many character homes in these suburbs have been renovated, sometimes multiple times. Modern bathrooms, new kitchens, and extensions have been added over the decades. The new plumbing in these renovations often connects to the original old drainage that runs to the street.
You might have a beautiful modern bathroom with new fixtures, but it drains into a clay pipe that was installed in 1920 and is full of tree roots. The new plumbing works perfectly. The old drainage underneath does not. Problems occur where the two systems meet.
Dense Blocks With Shared Boundaries
Original Norwood and Burnside blocks were often subdivided over the years, creating smaller properties with shared boundaries. Trees that once stood in the middle of a large block now sit on property lines or in neighbouring yards. Roots do not respect boundaries. A tree on the next property can send roots into your drains just as easily as a tree on your own land.
This creates complicated situations where the tree causing your drain problems belongs to someone else, and they may have no obligation or incentive to remove it.
Solutions That Actually Work in Norwood and Burnside
When you cannot remove the trees causing root problems, you need solutions that work around them. Here is what we recommend for homes in these suburbs.
CCTV Inspection First
Before recommending any solution, we send a camera through your drains to see exactly what is happening. The CCTV drain inspection shows us where roots are entering, how badly the pipe is damaged, whether there are multiple entry points, and what condition the pipe is in overall. This information is essential for choosing the right solution.
Root Cutting and High-Pressure Jetting
For immediate relief, we use mechanical cutting equipment to slice through root masses and high-pressure water jetting to flush everything out. This restores flow and clears the blockage. However, this is not a permanent solution on its own. The roots will grow back through the same entry points within months to a year.
Pipe Relining: The Permanent Solution
Pipe relining is the gold standard for root problems in suburbs like Norwood and Burnside. After clearing the roots, we insert a flexible liner coated with epoxy resin into the existing pipe. The liner is inflated against the pipe walls and cured to form a new, seamless pipe inside the old one.
The relined pipe has no joints or gaps for roots to enter. It is completely sealed from end to end. Tree roots cannot penetrate the cured epoxy material. The roots may continue growing around the outside of the pipe, but they cannot get back inside.
For high-value Norwood and Burnside properties, relining has another major advantage. It requires no excavation. We do not need to dig up your heritage garden, established landscaping, or paved areas. The work is done through existing access points, usually completed in a single day.
Pipe Replacement When Necessary
In cases where the pipe has completely collapsed or is too damaged for relining, replacement may be necessary. We use modern PVC pipes that have far fewer joints than old clay pipes and are much more resistant to root intrusion. Where possible, we use trenchless techniques to minimise excavation, but some digging may be unavoidable in severe cases.
What It Costs to Fix Root Problems Permanently
Understanding the costs helps you make informed decisions about temporary versus permanent solutions.
Root clearing and jetting – $300 to $500 per visit. Provides temporary relief, but roots will return within 6 to 12 months.
CCTV drain inspection – $150 to $250. Essential for understanding the problem and planning the right solution.
Pipe relining: $4,000 to $10,000 depending on pipe length, diameter and condition. Permanent solution witha 35 to 50-year warranty. No excavation required.
Pipe replacement with excavation – $8,000 to $20,000 or more, depending on length, depth and what needs to be dug up. May be necessary for severely collapsed pipes.
For many Norwood and Burnside homeowners, relining pays for itself within a few years compared to the cost of repeated clearing. And it protects a high-value property from ongoing drain problems that can affect saleability and insurance.

Frequently Asked Questions
- Can I make the council remove a street tree that is damaging my drains?
Generally no. Council street trees are maintained by the council and are rarely removed for drainage issues on private property. The council may trim roots in some circumstances, but this is temporary. Your best option is usually to fix your private drainage so it can withstand root pressure, such as through pipe relining.
- Is it worth relining pipes in a 100-year-old home?
Yes. A quality reline creates a new pipe essentially inside the old one, with a lifespan of 35 to 50 years. This is often more cost-effective than replacement, especially when excavation would damage heritage gardens, established landscaping, or paved areas. Many Norwood and Burnside homeowners choose relining specifically to avoid disruption to their properties.
- How often will I need root clearing if I do not get the pipe relined?
It depends on the tree species and how badly the pipe is damaged. With aggressive trees like figs and elms, and old clay pipes with multiple entry points, you may need to clear every 6 to 12 months. Some homeowners manage 18 to 24 months between clearings. The frequency typically increases over time as roots exploit the weakened pipe further.
- Can roots from my neighbour’s tree really block my drains?
Absolutely. Tree roots commonly extend 15 to 25 metres from the trunk. A large tree near the boundary of the next property can easily send roots into your yard and drainage system. Unfortunately, you cannot force your neighbour to remove their tree in most cases. You need to protect your own pipes from intrusion.
- Why are Norwood and Burnside worse than other leafy suburbs?
It is the combination of factors. Very old clay pipes with deteriorated joints, exceptionally large and established trees, council protection preventing tree removal, and dense subdivided blocks. Other leafy suburbs may have one or two of these factors. Norwood and Burnside have all of them together.
- Do chemical root killers work?
Copper sulphate and other root-killing products can slow regrowth, but they do not clear existing blockages, and they do not seal the entry points. They may buy you a few extra months between clearings,s but they are not a permanent solution. Mechanical cutting and jetting to clear roots, followed by relining to seal entry points, is the only permanent approach.
- Can you reline just part of the pipe where roots are entering?
Yes. If the CCTV inspection shows that root entry is limited to one section of pipe, we can do a patch repair to seal just that area. This is cheaper than relining the entire pipe. However, if there are multiple entry points or the whole pipe is deteriorated, full relining is usually more cost-effective.
- How long does pipe relining take?
Most residential relining jobs are completed in a single day. We clear the roots, prepare the pipe, install and cure the liner, and do a final camera check. You can usually use your drains again the same evening. There is no excavation, no restoration work, and minimal disruption to your day.
Protect Your Property From Adelaide’s Worst Root Problems
Living in Norwood or Burnside means enjoying some of Adelaide’s most beautiful streetscapes. The trade-off is that your drains are under constant attack from the same trees that make these suburbs so desirable. You cannot remove the trees, and you cannot stop the roots from seeking out your pipes.
What you can do is seal your pipes so roots cannot get in. Pipe relining creates a root-proof barrier inside your existing drainage, ending the cycle of recurring blockages and repeated clearing costs. It protects your high-value property without any excavation or damage to your established gardens and landscaping.
If you are dealing with recurring root blockages, the first step is a CCTV inspection to see exactly what is happening in your pipes. From there, we can recommend the most cost-effective solution for your specific situation.
