Drainage Design Services

At Courous, we deliver tailored drainage design solutions for residential, commercial, infrastructure, and strategic road projects across the UK.

Why Drainage Design Is Critical

Effective drainage design is essential for managing water sustainably, protecting developments, and ensuring environmental compliance. Whether for a new housing site, a commercial development, or critical infrastructure like highways, a robust drainage strategy minimises flood risk, prevents structural damage, and supports long-term sustainability goals.

At Courous, we provide expert drainage design solutions for projects of all sizes — from private developments to major national infrastructure schemes.
