Drainage Surveys

Drainage surveys provide an accurate picture of existing systems, including their position, levels and layout. This gives designers, contractors and clients reliable site data before construction, redevelopment or maintenance work begins. Having a clear understanding of what is already in place can help inform design decisions, coordinate proposed works and reduce the risk of unexpected problems on site. The resulting survey data provides a dependable record that can be used throughout the project and retained for future reference.

What can this type of survey include?

Depending on the project requirements, a drainage survey can record:

* Manholes and inspection chambers
* Drainage runs and connections
* Cover and invert levels
* Pipe sizes and directions
* Gullies and other drainage features
* Surface water and foul drainage systems
* Relevant surrounding site levels and features

Why are these surveys useful?

Accurate drainage information is particularly useful when planning construction, development or alterations. It helps identify existing drainage and potential issues before work begins, reducing uncertainty and helping projects progress more smoothly.

Who are these surveys for?

Drainage surveys are used by developers, contractors, groundworkers, drainage specialists, engineers, property professionals and homeowners who need accurate information about existing drainage infrastructure.
