What to do if your street is flooding after a storm

Heavy rain can overwhelm kerbs, gutters, culverts and underground drains within minutes. A street that has never flooded before may collect water when leaves block an inlet, a nearby creek rises, or runoff travels downhill from surrounding properties. Treat moving water as a serious hazard, even when it appears shallow.

Your first priority is personal safety. Stay indoors if your home is secure, keep children and pets away from drains, and avoid walking or driving through floodwater. Water can conceal potholes, open pits, fallen power lines, contaminated waste and strong currents.

In Australia, contact Triple Zero (000) for an immediate threat to life, while the State Emergency Service (SES) handles many storm and flood assistance requests through state-based numbers. In New South Wales, for example, the SES number is 132 500 for flood and storm help. Check your state or territory emergency service before severe weather arrives.

Council responsibilities and emergency procedures differ between Australian cities such as Brisbane, Sydney, Melbourne and Perth. A local council may clear public drains and manage roads, but private stormwater pipes, driveway crossings and retaining walls can belong to property owners. Report the problem promptly and record what you see without putting yourself at risk.

Move away from the immediate hazard

If water is entering your home, switch off electricity at the main switch only if you can do so without stepping into water. Do not touch electrical equipment while standing on a wet floor. If you smell gas, leave immediately, avoid flames and switches, and contact the gas distributor or emergency services from a safe location.

Move to higher ground if water is rising quickly, your building is unstable, or authorities issue an evacuation warning. Take essential medication, identification, a phone charger and pets if there is time, but do not delay to collect possessions. Never shelter in a basement, underground car park or low-lying garage during a flash flood.

Keep clear of roads and stormwater drains

A vehicle can lose traction or float in surprisingly little water. Floodwater may also hide a collapsed road edge or debris, so turn around rather than attempting to cross a flooded lane. Follow police, SES and council road closures, even if the route looks passable.

Do not remove a grate or reach into a blocked inlet. Report blocked drains, damaged signs, sinkholes and overflowing pits to your council’s after-hours number. If the issue is on a major road, contact the relevant state road authority as well. A photograph taken from dry ground, along with the street name and nearest property number, can help crews locate the problem.

Report the flooding with useful details

When you contact the council, explain whether the water is rising, where it is flowing, and whether homes, vehicles or public infrastructure are threatened. Mention blocked gutters, fallen trees, damaged kerbs, sewage odours, exposed utility covers and water entering buildings. Do not assume another resident has already reported it.

Keep a safe record of the time, rainfall, water depth and visible damage. Photographs can support an insurance claim, but never enter floodwater to obtain them. Local councils generally manage public drainage assets, while owners may need a licensed plumber or drainage contractor for private pipes. Check your policy before authorising major repairs, and use a licensed Australian tradie for electrical, gas or structural work.

Council stormwater charges help fund drainage maintenance in some municipalities. The explanation of stormwater fees describes one municipal approach, although Australian charges, rate structures and responsibilities depend on the local council.

Protect your household after the water recedes

Do not re-enter a flooded property until authorities or a qualified professional say it is safe. Floodwater can contain sewage, chemicals and sharp objects. Wear waterproof gloves, sturdy footwear and eye protection during cleanup, and keep children away from mud and damaged materials. Wash hands thoroughly and discard food, medicines and cosmetics touched by floodwater.

Have an electrician inspect wet wiring, appliances and switchboards before restoring power. Arrange a gas inspection if an appliance, meter or pipe was submerged. Photograph damage, retain receipts and notify your insurer promptly. In Australia, insurers may distinguish stormwater, river flooding and surface water in policy wording, so ask how your cover applies rather than assuming every type of inundation is included.

Only use sandbags where authorities recommend them, because poorly placed barriers can divert water towards another home. In many Australian suburbs, supplies at hardware stores can sell out before a major weather system, so keep reusable barriers, drain covers and cleaning equipment ready during the wet season.

Reduce the risk before the next storm

Clear leaves from gutters and downpipes, secure outdoor furniture and check that private drains are free of obvious blockages before rain begins. Do not sweep rubbish into the kerb, because it can obstruct grates. Tree roots, building work and unapproved alterations can also affect drainage, so use licensed contractors and obtain required council approvals.

Learn your property’s low points and identify a safe route to higher ground. Save council, SES, utility and insurer numbers in your phone, and follow official warnings rather than relying only on neighbourhood social media. State planning rules and flood maps can affect renovations, extensions and development approvals, particularly in low-lying parts of Brisbane, northern New South Wales and regional Queensland.

Public works teams maintain roads, drains and other shared assets through all weather conditions. People interested in contributing to that work can read about a public works apprenticeship, while residents seeking municipal contacts, utility information and infrastructure updates can visit the Public Works Department website. Reliable reporting and sensible preparation help crews restore safe access faster after the storm.
