Surface water drainage is the system designed to collect and carry away rainwater from your property. This includes water that lands on your roof, driveway, patio, and garden. A good system prevents this water from pooling, flooding your property, or overwhelming the public sewerage system. It directs rainwater away safely, usually to a dedicated surface water sewer, a soakaway on your property, or a nearby watercourse.

Ideally, rainwater should flow into a separate surface water system. Many modern properties have two sets of drains: one for foul water (from toilets, sinks, showers) and one for surface water (rainwater). The rainwater from your gutters and driveway should be connected to the surface water drains. These drains then typically lead to a public surface water sewer or a soakaway, which allows the water to soak naturally back into the ground.

This is a common problem, especially with paved driveways where water can't soak away. We can help by installing effective surface water collection systems. This often involves fitting channel drains (sometimes known as Aco drains) across your driveway to collect the water before it can pool. From there, we can connect this new drain to an existing surface water system or construct a new soakaway to manage the water flow safely and efficiently.

No, you shouldn't. Connecting a rainwater pipe to the foul sewer is known as a misconnection and is illegal in many cases. Foul sewers are only designed to handle waste from your property. During heavy rain, extra water from roofs and driveways can overwhelm the sewer, causing it to back up and flood homes and roads with raw sewage. If you suspect a misconnection at your property, we can investigate and provide the right drainage solution.

A soakaway is essentially a large, gravel-filled pit dug underground. It collects rainwater from your surface water drains and allows it to percolate slowly and naturally into the surrounding soil. You might need one if your property isn't connected to a public surface water sewer, or if you are building an extension or a new driveway and need to manage the extra rainwater runoff on-site. We can assess your property's ground conditions and install a soakaway that meets all local building regulations.

The gullies and drains located on the public road are typically the responsibility of your local council or Highways Agency. However, the pipe that connects your property's drainage system to the main public sewer under the road is often your responsibility up to the property boundary. The public sewer itself is maintained by the local water company (like United Utilities). If you are unsure which part of the system is blocked or damaged, our CCTV surveys can help identify the problem and determine who is responsible for the repair.
