Professional SuDS Consultants Near You
At Courous, we believe effective drainage should do more than move water away – it should protect people, safeguard property, and coexist harmoniously with the environment. That’s why our experienced SuDS design consultants specialise in creating sustainable drainage strategies that are practical, affordable, and fully compliant with planning regulations.
Every project is unique, so we start with a detailed site evaluation to recognise the explicit challenges of your space. Based on this assessment, we design tailored systems that may include swales, soakaways, rain gardens, permeable paving, green roofs, or attenuation tanks. These systems are chosen to suit the site conditions and long-term goals of your development.
By blending technical expertise with innovative design, we help residential, commercial, and industrial projects reduce flood risk, improve water quality, and meet environmental standards. With us, you get a partner that delivers drainage solutions that are robust today and sustainable for the future.

Drainage Design Consultancy – Our Detailed Approach
Initial Consultation: We begin by collecting all the essential details about your project. After the consultation, our SuDS consultancy will provide a free quote with estimated costs and expected completion time.
Site Survey: Our engineers will visit your site to assess the soil condition, water flow, and other constraints. This assessment will support determining the appropriate types of SuDs for the site.
Create SuDs Design: Next, we calculate the storage capacity and water flow rates to create the SuDs design using industry-leading software.
Regulatory Compliance: After designing the sustainable drainage system, we prepare a comprehensive report that complies with local authority regulations.
