Williamstown, from a plumber's point of view
Terraces and townhouses
At the 2021 Census, 30.2% of occupied homes in the suburb of Williamstown were terraces, townhouses or semis, 13.2% flats and 56.2% separate houses.
Settled owners
40.3% of homes were owned outright and 24.5% rented, and the median age was 45.
The outlet is private
Hobsons Bay says a property's stormwater outlet up to the legal point of discharge is a private asset.
Significant trees
Hobsons Bay's Community Local Law 2025 protects trees on private land with a trunk circumference of 110 cm or more at 1.4 m above ground.
Stormwater: where Council takes over
Hobsons Bay makes owners responsible for all stormwater drainage on their land and for the drain from the property to Council's drain. Council looks after the gutters, drains and pits in public roads and its own drains in easements, designated easements on private property included. The legal point of discharge is a point Council designates for all of a property's runoff.
Council is progressively flood mapping parts of the municipality to plan mitigation works. If street water reaches your block in heavy rain, report it to Council, and have a plumber confirm your own drains and outlet are clear.
Terrace rows and shared lines
In a terrace row or a townhouse block, one stormwater or sewer line can serve several homes. Before a plumber starts, check the title or ask the owners corporation who owns the pipe, so the cost lands with the right people. A CCTV drain inspection shows where each line runs.
Trees over the fence count too
The local law needs a permit to interfere with, remove, damage or kill a significant tree, and that includes one overhanging from a neighbour's property. Council also expects builders and owners doing building works to protect trees beside the site, and Clause 52.37 can add a planning permit for canopy trees in residential zones.
So if roots from next door have broken your drain, talk to Council before anyone cuts them. Our page on tree roots in drains explains the repair options.
Your water retailer
Williamstown is on neither South East Water's nor Yarra Valley Water's supply list, and no official page we read names its retailer. Look at your water bill. Some older material still names City West Water, which joined Western Water on 1 July 2021 to become Greater Western Water.
What we would do
On a Williamstown drain job, settle whose pipe it is before anything else: yours, a shared line in a terrace row, or Council's drain in an easement. If a protected tree is involved, even one over the fence, get Council's view before roots are cut. A camera inspection answers most of these questions.
