Our commercial drainage surveys are trusted by companies and local authorities throughout Bristol, Cardiff, Reading, Bath and Swindon, as well as across Gloucester, Newport, Chippenham, Weston-super-Mare, Taunton, Somerset and Wiltshire.
Commercial drain mapping is the process of tracing, documenting and accurately recording the structure of underground drainage systems for non-domestic sites. Unlike domestic properties, commercial drainage networks often involve multiple inspection chambers, large diameter pipes, interceptors, flow controls, gullies and connections across multiple levels or buildings.
Our specialist team uses advanced technology — including CCTV drainage cameras, dye tracing, GPS positioning, sonar and laser profiling — to build a complete picture of your network. This allows us to produce highly accurate plans, flow diagrams and condition reports that support compliance and asset management.
We follow a structured, professional survey process designed to deliver accurate data quickly and efficiently. This process is ideal for commercial developments, office complexes, retail parks, industrial units, housing developments, care homes, schools and hospitals.
We start by reviewing any existing plans or as-built drawings and identifying key access points on site. This ensures the mapping process is efficient and minimally disruptive.
Our engineers deploy CCTV drainage rigs, tracer dye, sonar profiling and GPS equipment to trace the entire network. Every line, junction and chamber is recorded.
All captured data is compiled into accurate CAD or GIS maps showing drain runs, inspection chamber locations, flow directions, pipe diameters and gradients.
We score the condition of each line, highlight defects such as cracks or root ingress, and provide recommendations for remedial work if required.
For large or complex sites, we can provide periodic re-surveys, updated asset registers and maintenance schedules.
