Can the council give me a flood report for my Dianella home?

No. The City of Stirling says it has no flood mapping data and can't provide letters for home insurance, and outside river studies the Department of Water and Water Corporation don't have it either.

A street tree's roots are in my drain. Can I cut the tree back?

Not yourself. In Stirling, pruning, damaging or removing a street tree without authority counts as vandalism. Have the roots cleared from your own pipe and report the tree to the City.

Plumbers in Dianella: Stirling drains, tree roots and street trees

Plumbers in Dianella Sand, roots and drains.

Housing in Dianella began in the 1960s, on sandy soil, and today most homes are houses with a large share owned outright. The City of Stirling runs the street drains; Water Corporation runs the sewer and the main drains. Describe it in a few lines and we'll match the job with a licence-checked specialist in that kind of work.

Dianella facts that change a job

Built from the 1960s

The City of Stirling says sandy soil held Dianella back until the 1960s, when housing construction began north from Walter Road and Grand Promenade.

Houses and long-term owners

At the 2021 Census, 71.5% of the suburb's occupied homes were separate houses and 24.4% townhouses, terraces or semis. 38.9% were owned outright.

Who runs which drain

Stirling's stormwater network has 720 km of pipes, about 29,000 pits and chambers and 220 sumps. The main drains and the sewerage belong to Water Corporation.

Street trees are protected

Pruning, damaging or removing a street tree without authority is treated as vandalism in Stirling, and penalties may apply.

Roots in the pipes

Stirling looks for root intrusion in its own stormwater pipes with cameras, then clears the roots with high pressure water jets and cutting equipment. For roots in your own drains, ask a drain specialist for a camera inspection before any digging.

If the roots come from a street tree, leave the tree alone and contact the City.

On the sewer, your line runs to the junction on Water Corporation's main. A blockage on your side is your cost; if it's in the main, Water Corporation pays the plumber a set fee for locating it.

Floods and stormwater

Stirling has no flood mapping data, so it can't write flood-risk letters for home insurance. Outside river studies, the state's Department of Water and Water Corporation can't either.

In WA, local governments manage stormwater. Water Corporation runs over 40% of Perth's urban drainage network, including larger main drains that council systems can feed into.

Check any plumber on the WA Online Licence Search. Then try blocked drains in Perth, tree roots in drains or stormwater.

What we would do

If a Dianella drain keeps blocking, get a camera inspection before you pay for a dig. It shows whether roots, a broken pipe or something else is the cause, and which side of the junction it's on. If the roots belong to a street tree, report it to Stirling and let the City deal with the tree.
