With **170mm of rain** hitting Mildura and surrounds recently (leading to flash flooding, overflowing drains, and SES call-outs spiking), many homes in the region are at risk of water damage—especially from blocked stormwater systems, poor drainage, or low-lying spots. Mildura Rural City Council and VicSES emphasize preparation over reaction, as flash floods here often stem from intense, short bursts overwhelming urban drainage rather than major river rises.
Here are practical, actionable **flood prevention tips** for Mildura homeowners, based on local council advice, VicSES guidelines, and general Victorian flood-resilient measures. These focus on low-to-medium cost steps you can take now to reduce risks for future heavy rain events.
# # # Quick & Low-Cost Prevention Steps (Do These Today)
- **Clear gutters and downpipes**: Remove leaves, debris, and nests—blocked gutters cause overflow that seeps into walls/roofs. Direct downspouts at least 2–3m away from the foundation (use extensions if needed).
- **Check and clean stormwater drains/pits**: Ensure grates around your property are free of rubbish. Mildura's urban flash flooding often starts here—clear them before the next storm.
- **Improve yard grading/drainage**: Make sure soil slopes away from your house (at least 5cm drop over 3m). Fill low spots near foundations with compacted soil or add swales/French drains to redirect runoff.
- **Seal entry points**: Use waterproof caulk/sealant around doors, windows, vents, and garage edges. Install door sweeps or sandbags as temporary barriers for low thresholds.
- **Install backflow valves**: Fit non-return valves on sewer/stormwater pipes to stop contaminated water backing up into your home (common in heavy rain). A plumber can add these for $500–$1,500.
- **Elevate valuables/utilities**: Move electrical outlets, appliances, and important items above potential flood levels. If you have a sump pump, add a battery backup.
# # # Medium-Cost Upgrades (Worth Considering in Flood-Prone Spots)
- **Sump pump with battery backup**: Essential for homes with basements or low-lying slabs—pumps out groundwater before it floods in. $800–$2,000 installed.
- **Flood vents/pressure relief**: Install vents in crawlspaces/garages to equalize pressure and reduce structural stress (prevents walls bowing).
- **Flood-resistant materials**: Use sealed concrete floors or water-resistant drywall in vulnerable areas (e.g., garages/laundries).
- **Temporary barriers**: Deploy sandbags, flood doors, or removable barriers at doors/garages for short warnings (VicSES/Mildura Council can advise on local suppliers).
# # # Long-Term/Structural Options
- **Elevate critical systems**: Raise electrical panels, HVAC, and hot water systems above flood levels (ties into your recent heat pump course—heat pumps can be positioned higher for resilience).
- **Landscaping for diversion**: Berms (raised earth mounds) or rain gardens to redirect water away from the house.
- **Check your flood risk**: Use VicSES Local Flood Guides (search Mildura on ses.vic.gov.au) or Mildura Rural City Council flood info to see if your property is in a high-risk zone. Consider flood insurance add-ons (standard home policies often exclude it).
**Key Safety Reminders from Mildura Council & VicSES**:
- Never drive through floodwater ("15 to float" – 15cm can float a car).
- Stay indoors away from windows/drains during heavy rain.
- Monitor VicEmergency app/website or ABC radio for warnings.
- If water enters your home, turn off power/gas and evacuate if advised.
