Flooding Tips for Homeowners
With Storm Éowyn forecasted to bring strong winds and heavy rain, homeowners should be aware of potential flooding risks to their septic tanks or sewage treatment plants. Excessive rainfall can overwhelm drainage systems, leading to failures that can cause costly damage and environmental hazards.
💧 What is Surface Water?
Surface water refers to rainwater runoff from roofs, gutters, driveways, roadways, and patios. During heavy rain, this water accumulates and raises water tables, affecting drainage fields and soakaways. If these become saturated, wastewater may not be able to disperse properly, leading to system backups and potential flooding. Additionally, rising water levels in local watercourses can further contribute to drainage system failures.
🚨 Signs of Septic System Failure
If your system is struggling due to flooding, you may notice:
- Flooded patches in your garden – water pooling in areas near your septic tank or drainage field.
- Difficulty flushing toilets – slow drainage or backups in sinks, toilets, and drains.
- Unpleasant odours – foul smells around your property, indicating a drainage issue.
- Flooded drain runs – standing water inside drainpipes, leading to slow wastewater discharge.
- More frequent need for tank emptying – increased accumulation of water inside your tank.
⚠️ How to Reduce the Risk of Flooding
Taking proactive steps can help protect your drainage system from flooding issues:
1. Separate Drainage Systems
Ensure surface water drainage (gutters, driveways, and ditches) do not connect to your septic tank or sewage treatment plant. Only foul water from household waste should enter these systems.
2. Upgrade Older Systems
Older septic systems may not be able to cope with extreme weather conditions. If you experience recurring drainage issues, it may be time to upgrade to a more efficient system.
3. Regular Maintenance & Servicing
Routine servicing and emptying of your septic tank or sewage treatment plant ensure optimal performance and help prevent unexpected failures. Don’t wait for an emergency - schedule maintenance before storms hit.
4. Keep Ditches Clear
If you have a responsibility for ditches on your property, ensure they are free from debris and blockages. A clear ditch allows water to flow freely and reduces the risk of localised flooding.
5. Proper Pipe Placement
Pipes discharging into watercourses should be installed at the correct height to account for fluctuations in water levels. In some cases, a pumped outlet may be required instead of a gravity-fed system to prevent flooding and maintain system efficiency.
🌟 Stay Prepared!
Storm Éowyn highlights the importance of proactive measures to prevent drainage issues, but homeowners should always be mindful of the risks posed by unexpected excessive rainfall. Ensuring proper drainage, regular maintenance, and system upgrades where necessary can help protect your property from flooding disasters.
