Rainwater Drainage — Surface Water & Rainwater Drainage Systems in East Sussex & Kent
If rainwater is flooding your garden, running off your driveway, or pooling around your property, you need a rainwater drainage system. As rainwater drainage contractors based in Battle, East Sussex, we design and install rainwater drainage systems for homes, farms, and development sites across Kent and East Sussex. We own our own excavators and plant, so we handle the full installation from excavation through to connection and reinstatement.
Rainwater drainage — also called surface water drainage — manages the rain that falls on roofs, driveways, paths, and hard surfaces. Without proper drainage, this water accumulates, floods, and causes damage. A well-designed rainwater drainage system intercepts, conveys, and disposes of rainwater safely, protecting your property and land from flooding.
Common Rainwater Drainage Problems
Surface water flooding is the most common rainwater drainage problem. When rain falls on impermeable surfaces — roofs, driveways, patios — it runs off rather than soaking in. Without a drainage system to intercept it, the water collects in low spots, floods gardens and driveways, and can enter properties. On the clay soils of Kent and East Sussex, the ground often can't absorb the runoff, making drainage essential.
Blocked or inadequate rainwater drainage is another frequent issue. Old drainage systems — broken pipes, silted-up soakaways, collapsed channels — no longer cope with the volume of rainwater, especially during the heavier storms that are becoming more common. The result is flooding that gets worse each year as the system deteriorates.
Downpipe and roof drainage problems cause water to discharge against the property rather than away from it. Downpipes that discharge onto hard surfaces, broken or missing drainage connections, and inadequate gutters all contribute to rainwater pooling around foundations, causing damp, settlement, and structural damage.
Our Rainwater Drainage Services
We install surface water drainage systems — drainage channels, ACO drains, and French drains — to intercept rainwater from driveways, paths, and hard surfaces and convey it to a soakaway, watercourse, or sewer. We also install rainwater harvesting systems that collect roof water for garden and non-potable use, reducing runoff and providing a free water source.
We install soakaways — gravel-filled or modular crate systems — that allow rainwater to infiltrate into the ground. On clay soils where infiltration is poor, we install attenuation systems that store rainwater and release it slowly to a watercourse or sewer. We also install land drainage and French drains to manage rainwater on larger areas like fields and gardens.
We connect downpipes and roof drainage to the surface water system, ensuring rainwater is conveyed away from the property and discharged safely. All rainwater drainage work is carried out with our own excavators — we handle the full process from excavation through to pipe installation, connection, and reinstatement. We're based in Battle, East Sussex and cover all of Kent and East Sussex. Call us on 07376 622637 for a free rainwater drainage quote.

Frequently Asked Questions
What is rainwater drainage?
Rainwater drainage — also called surface water drainage — manages rain that falls on roofs, driveways, and hard surfaces. It uses drainage channels, French drains, soakaways, and attenuation systems to intercept, convey, and dispose of rainwater safely. We install rainwater drainage across Kent and East Sussex.
How much does rainwater drainage cost?
The cost depends on the type of system, the area to be drained, the ground conditions, and the outfall. Drainage channels and French drains cost less than soakaways or attenuation systems. We provide free, no-obligation quotes after a site visit — call 07376 622637.
Do soakaways work on clay soil?
Soakaways rely on the ground's ability to absorb water, so they don't work well on heavy clay soils like the Wealden clay of Kent and East Sussex. On clay, we install attenuation systems that store rainwater and release it slowly to a watercourse or sewer, rather than relying on infiltration.
Can you connect rainwater drainage to the sewer?
Surface water drainage can discharge to a sewer where no watercourse or soakaway is available, subject to the water authority's consent and capacity. We can advise on the right outfall for your rainwater drainage system and handle the connection.
