Why roots keep coming back
Bayside puts it plainly: a properly built pipe withstands normal roots, but poor or failed joints let fine roots into a cracked pipe, where they keep growing. Cutting them out only buys time. Replacing or repairing the damaged section is the permanent fix.
That's worth knowing before you pay for another root clean. Ask for a camera inspection to see the joint, then weigh a repair against pipe relining.
Sandringham facts for a drain job
Your pipe to the kerb
Bayside says house stormwater pipes and legal point of discharge pipes are the owner's, from inside the property to Council's pipes, pits or kerb. They run in an easement or under the footpath and nature strip.
Council's network
Bayside maintains 415 kilometres of drainage pipes and more than 15,500 pits, with a yearly program of jetting, root cutting and cleaning.
A mix of homes
At the 2021 Census, the suburb of Sandringham was 50.0% separate houses, 22.4% semis or townhouses and 26.8% flats or apartments. 39.6% of homes were owned outright.
Big trees need a permit
Where no planning permit is needed, Bayside still needs a Local Law permit to remove or lop a tree with a trunk over 155 centimetres around, measured 1 metre above ground.
Replacing a stormwater line in Bayside
Bayside's approved stormwater pipe materials are reinforced concrete with class 2 rubber ring joints, cast iron to AS1631, and class 12 UPVC to AS3500.1. A pipe from a house should be at least 100mm across, and it should run by gravity, not a pump, unless Council's Infrastructure staff agree first.
Not sure where your pipe is meant to discharge? Request a legal point of discharge online. Council assesses it in 5 to 10 working days and emails a letter with a services plan. Digging under the footpath or nature strip needs a Road Opening Permit.
Sewer pipes and big trees
Sewage leaves your property for a main that South East Water maintains. Its responsibility runs to the inspection opening near the boundary, and the pipe on the house side is the owner's. Note that South East Water won't reimburse a job where tree roots were cleared, even when the blockage was on its side.
If the fix means taking out a large tree, check Bayside's permit rules first, including the Clause 52.37 canopy tree controls that have applied across its residential areas since 15 September 2025.
What we would do
If your Sandringham drain has been cleared of roots more than once, stop paying for clearing and get the failed joint found. A camera shows where the pipe has given way, and Bayside's own advice is that repair or replacement is what lasts. Send us the job and a licence-checked drain specialist can quote both options.
