Tree Roots and Council Trees: Who Pays When Roots Block Your Drain?

It is one of the most common arguments between Melbourne homeowners and their local council: you have a blocked sewer, the CCTV camera shows a council street tree’s roots have grown through your pipe, and now you are looking at a $3,000-$8,000 bill. Who actually pays? The answer is more nuanced than most people expect.

The legal starting position

In Victoria, the sewer pipe from your house to the property boundary is the homeowner’s responsibility. The trunk sewer in the street is the water authority’s (Yarra Valley Water at yvw.com.au, South East Water at southeastwater.com.au, or Greater Western Water at gww.com.au depending on suburb). The street tree itself is usually the council’s.

The blockage is on your pipe. The roots came from the council’s tree. Welcome to the grey zone.

What usually happens

Most councils have policies that recognise the issue but limit their liability. Whitehorse, Boroondara, Monash, Manningham, and Knox all have published nuisance and damage policies. In practice, councils will rarely pay for the full repair, but they will often contribute to the cost of removing the tree, cutting the roots, or reimbursing a portion of the plumbing work - if you follow the right process.

The wrong order is: dig up the pipe, fix the problem, then write to the council asking for reimbursement. By then there is no evidence and no leverage.

The right order, step by step

First, when you have a blocked drain, get a licensed plumber to do a CCTV inspection and document the location, depth, and extent of root intrusion. A clear video and a written report is the evidence base for any council claim.

Second, identify the tree. If the roots are coming from a tree on a council nature strip or in a council park within reasonable proximity, that is council jurisdiction.

Third, lodge a formal claim or service request with the council before commencing repairs - include the CCTV evidence, the plumber’s quote, and a description of the tree. Many councils have a specific tree root damage application form.

Fourth, get a written response. Some councils approve removing the offending tree at their cost. Some contribute to the repair (commonly 25-50%). Some refuse. Either way, you now have a paper trail.

Fifth, repair the pipe. Pipe relining (CIPP) is often a better option than full excavation here, because it does not require disturbing the council tree, which avoids a second argument about tree damage.

What about insurance?

Most home insurance policies in Australia specifically exclude gradual damage from tree roots. The ACCC (accc.gov.au) and Insurance Council of Australia (insurancecouncil.com.au) confirm this is standard. A sudden collapse may be covered; chronic infiltration generally is not.

FAQ

Does the council have to remove the tree?

Not necessarily. Most councils balance street tree value against ongoing damage; expect negotiation.

Is it worth pursuing a claim for a small contribution?

If the repair is $3,000+ and the council might contribute $1,000, usually yes.

What if it is a neighbour’s tree, not council’s?

That is a civil matter between neighbours - Consumer Affairs Victoria (consumer.vic.gov.au) and your local Dispute Settlement Centre can advise.
