Frequently Asked Questions

What is the difference between foul and surface water drainage?

Foul water drainage design manages wastewater from bathrooms, kitchens, and appliances, while surface water systems handle rainwater from roofs and hard surfaces.

How much does foul water design typically cost?

The cost depends on site complexity, project size, and approval requirements. We provide tailored, competitive quotes for every design. For an accurate quote, we recommend discussing your project during the consultation.

Why do I need a drainage survey when buying a property?

A drainage survey, often conducted using a CCTV camera, is not included in a standard home inspection. It is a critical extra step, especially for older properties, as it can identify potential problems such as blockages, root intrusion, or collapsed pipes that could lead to expensive repairs if left unchecked.

What are the key regulations governing drainage design?

In the UK, drainage design is primarily governed by Part H of the Building Regulations. This document provides guidance on wastewater and rainwater disposal, specifying minimum requirements for pipe gradients, diameters, and the separation of foul and surface water systems.

When should drainage be considered in a project?

Drainage should be considered early in the project, alongside topography, hydrology, and layout design, to ensure effective integration with other site strategies.
