Who Is Responsible for Stormwater Drains: You or the Council?

Updated July 2026 · 7 min read · Geelong Emergency Plumbing

Stormwater drain responsibility is one of those questions where the correct answer — it depends on location — sounds evasive until the framework clicks into place, at which point most disputes become straightforward. The principle is simple: who owns the asset owns the maintenance obligation. The complexity is knowing which asset is whose.

The Boundary Rule

In Victoria (and consistent with most Australian states), the standard division is your property boundary:

• Within your boundary — gutters, downpipes, under-slab pipes, yard drainage, pits and the pipes connecting them: your responsibility. This includes the connection point to the council asset at or near the boundary.
• Beyond your boundary in public land — kerb drainage, street stormwater pipes, council pits and the stormwater network carrying water to waterways: council's responsibility (City of Greater Geelong in the local context).
• Sewer lines — separate from stormwater, maintained by the water authority (Barwon Water for Geelong and the Bellarine). Sewer pipes within your boundary are yours; the main beyond the boundary is theirs.

The Complication: Where Exactly Is the Boundary?

The legal boundary is not always the fence line. Many properties have easements extending beyond the fence, or boundary variations that create ambiguity. For drainage specifically, the relevant point is usually the inspection opening or connection junction nearest the boundary — pipes on the house side of that junction are yours; pipes on the network side are the authority's. When a blockage falls near that junction, a CCTV inspection that pinpoints the location precisely is worth far more than arguing about the fence line. It's also the document that determines who pays for the repair — a council who receives footage showing a blockage in their asset pays for the fix; a homeowner with footage showing it's on their side of the junction does the same math in reverse.

Common Misunderstandings

"The drain is in the footpath, so it's the council's problem." Sometimes, but not always — some private drain connections run through footpath easements. Check whether the pipe is yours before assuming.

"My neighbour's overflow is flooding my property — they must fix their drain." If a neighbour's property is genuinely directing stormwater onto yours, they have a nuisance obligation, but councils don't always get involved in private-party disputes. In practice, this often ends up with a stormwater engineer, a drain solution, and a conversation about who contributes what.

"The council said it's not their drain." Council responses to stormwater complaints vary widely. If you genuinely believe the blocked asset is council infrastructure, put the request in writing (email to their service request system), include photos, and reference the street address. Written requests create accountability that phone calls don't.

How to Report a Council Drain

City of Greater Geelong: online service requests at the council website, or call the customer service line. Include the street address, photos if possible, and describe the issue — "blocked stormwater drain at [address] causing flooding onto my property during rain events." Written requests with photos generate reference numbers that can be followed up; verbal reports can disappear. If the response is slow and flooding is causing property damage, escalate in writing noting the damage and dates.

When Stormwater and Sewer Are Confused

The two networks are completely separate: stormwater carries rainwater to waterways; sewers carry waste to treatment. Connecting one to the other — deliberately or by misidentifying pipes — is illegal, polluting and a significant rectification cost. If you're having drainage work done and are unsure which pipe is which, a CCTV inspection with a licensed plumber identifies both before any connections are disturbed. Old Geelong properties occasionally have legacy cross-connections from an era of looser standards; finding and correcting them during drain work saves a larger problem later.

For the Geelong Region Specifically

Stormwater infrastructure across the City of Greater Geelong falls under council; the Bellarine Water Supply District includes areas where Barwon Water has specific responsibilities for rural supply and some sewerage. The Golden Plains Shire covers Bannockburn. When a property spans or abuts the jurisdiction boundary, the relevant authority is whichever manages the asset — starting with whichever boundary the drain is closest to and escalating from there.

For major drainage issues — a long-running flooding problem, significant infrastructure failure, or a situation where the responsible party is genuinely disputed — it's worth contacting a private drainage engineer as well as the relevant authority. A drainage engineer's assessment carries weight in council negotiations and insurance claims that a plumber's invoice alone doesn't always carry. They can also design solutions that address the root cause of complex drainage problems rather than clearing the symptom repeatedly.
