If you’re planning a new extension, conservatory, or driveway in Southampton, there’s more to consider than just the build itself. Local regulations and Sustainable Drainage Systems (SUDS) requirements mean that new impermeable surfaces—like tarmac, concrete, or paving—must not increase the risk of flooding or surface water buildup.
That’s where soakaways come in.
💧 What Is a Soakaway?
A soakaway is a subsurface drainage solution that allows excess rainwater to filter back into the ground rather than overloading local drainage systems. They’re often used to manage water from roofs, patios, and driveways.
📜 The Legal Requirement: Why You Might Need a Soakaway
In Southampton, SUDS compliance is mandatory for many developments involving hard surfaces. Local planning authorities and building control officers may reject your extension or driveway plans if they don’t include appropriate drainage.
You may legally require a soakaway if:
- You’re adding a driveway larger than 5m²
- You’re extending your home’s footprint
- The project creates surfaces that prevent water infiltration
In these cases, drainage installations such as soakaways or permeable paving systems are strongly encouraged—or even legally required—to reduce the risk of blocked drains in Southampton during heavy rainfall.
⚠️ Why It Matters: The Risks of Non-Compliance
Neglecting proper drainage could lead to:
- Surface water flooding
- Blocked drains in Southampton homes
- Fines or delays from local planning authorities
- Damage to your property or neighbours’ properties
In short: water has to go somewhere. Without a soakaway, it might end up in your kitchen or garden.
