Land Drainage Design Services

At Courous, we provide expert land drainage design services to support developers, landowners, and infrastructure providers in managing surface and groundwater effectively. Our work is guided by the principles of the Land Drainage Act 1991, ensuring full compliance with statutory obligations and industry best practice.

Why Land Drainage Matters

Effective land drainage is essential for protecting developments, agricultural land, highways, and infrastructure from waterlogging, erosion, and long-term damage. Poor drainage can lead to increased flood risk, structural instability, and loss of land usability. The Land Drainage Act 1991 places responsibility on landowners and relevant authorities to ensure proper flow is maintained and obstructions are prevented in watercourses.

At Courous, our specialist team delivers reliable, sustainable, and regulation-compliant drainage design tailored to the unique needs of each site.
