Preparing for Summer Storms: Preventing Drainage Issues and Sudden Outbursts

Preparing for Summer Storms

As summer approaches, it doesn’t just bring sunshine and warmer days, it also brings sudden storms, heavy rainfall, and unexpected drainage issues. Storm drains in the UK can quickly become overwhelmed, and for properties and infrastructure managed by Drasin Division, being prepared is key to avoiding costly damage and disruption.

Understanding the Risk

Summer storms often hit quickly and without much warning. Intense downpours can put pressure on drainage systems, especially if they’re already partially blocked. This is often when drains blocked after heavy rain become a serious issue.

Common Causes of Drainage Blockages

Before prevention, it’s important to understand what typically causes blockages:

• Debris buildup (leaves, dirt, litter)
• Grease and fat accumulation in pipes
• Tree root intrusion
• Collapsed or damaged pipework
• Silt and sediment buildup in external drains

These problems can significantly reduce the effectiveness of storm drains, especially during periods of heavy rainfall.

Preventative Measures You Can Take

The good news is that many drainage issues can be prevented with proactive care. Here are some key steps:

1. Regular Drain Inspections

Scheduling routine inspections helps identify minor issues before they become major problems. CCTV drain surveys are especially effective for spotting hidden blockages or structural damage.

2. Drain Cleaning and Maintenance

Periodic cleaning removes debris, grease, and buildup. This ensures water flows freely, even during heavy rainfall.

3. Clear External Areas

Make sure gutters, grates, and outdoor drains are free from leaves and debris, especially after windy weather.

4. Monitor Tree Growth

Tree roots are a common cause of underground pipe damage. Regularly assess nearby vegetation and consider root management solutions if necessary.

5. Install Drain Guards or Filters

These simple additions can prevent larger debris from entering the drainage system in the first place.

What To Do During a Storm

Even with preparation, extreme weather can still test your system. During heavy rainfall:

• Avoid using excess water indoors (e.g., limit laundry or dishwashing)
• Keep an eye on slow-draining sinks or toilets
• Check outdoor drains for visible overflow
• Act quickly if you notice unusual smells or water backup

Emergency Response

If you experience drains blocked after heavy rain or any overflow:

• Contact a professional drainage service immediately
• Avoid attempting to clear severe blockages yourself
• Keep affected areas clear to minimise damage

Fast response can prevent further complications and reduce repair costs.

Final Thoughts

Summer storms may be unpredictable, but your drainage system doesn’t have to be. With the right preparation and regular maintenance, you can reduce the risk of blockages and keep everything running smoothly, even when storm drains in the UK are under pressure.
