About Courous
Courous is a civil engineering consultancy specialising in drainage design, flood risk, and sustainable surface water management. We work with developers, architects, planning consultants, and contractors to provide clear, reliable design solutions that get projects moving.
We’re based in Lancashire and support projects across the North West and wider UK. From small housing developments to major infrastructure schemes, we bring the same level of technical care and attention to every site.
What We Do
We help clients solve drainage and surface water issues across planning, design, and construction stages. Whether it’s a drainage strategy for planning approval, SuDS design for a new site, or helping resolve a planning objection, we provide straightforward advice backed by strong engineering principles.
We also work on Section 278 and Section 38 highway drainage design, outfall assessments, pollution control, and discharge consents. Our team understands what local authorities, the Environment Agency, and water companies want to see—so we make sure you get approved without unnecessary delays.
