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.

Frequently Asked Questions

Why does water still pool on my land even after installing drains?

Poor grading or slope is often to blame; if the ground doesn’t slope away from buildings or low spots, water will collect there. Also, undersized drains, blocked outlets, or compacted soil can make drainage ineffective.

Can tree roots or soil type ruin a drainage system?

Yes. Roots can infiltrate pipes and joints, causing blockages and damage. Heavy clay soils drain poorly and can preventwater from percolating, while sandy soils may let water escape too quickly. Proper soil testing and specifying root barriers or suitable pipe materials are essential.

How do regulations or planning permissions affect my drainage design?

Very much so. Local authorities often require drainage plans that comply with rules about flood risk, sustainable drainage (“SuDS”), and outlet approvals, among other regulations. Failure to adhere can cause delays, rejections, or extra costs. Early consultation with planners and checking local drainage policies helps avoid issues.

What happens if heavy rainfall exceeds what the drainage design expects?

If a system isn’t designed for peak flow or extreme weather events, it may overflow, flood, or underperform during heavy rain. It’s important to include buffers, retention or detention systems, and consider climate trends when planning.
