Drain Tracing
Drain tracing uses electronic sonde transmitters and signal receivers to locate and map the route of underground drain pipes. It's essential when you need to know exactly where drains run — for building work, extensions, or when drainage plans aren't available.
Most teams review drain tracing when live project risk needs turning into a clear technical decision with practical next steps.

Situations where this applies
Teams usually investigate drain tracing when early warning signs start affecting reliability, compliance, or project timelines. This is often the point where decision makers move from observation into scoped technical action.
Common warning signs
The symptoms below are the most common triggers we see before diagnosis and repair planning.
- No drainage plans available for the property
- Planning a building extension or renovation
- Need to locate a drain before excavation work
- Investigating the route of a drain causing problems
- Required for building over sewer applications
What the work typically involves
We insert a sonde (electronic transmitter) into the drainage system via a CCTV camera or push rod. Above ground, we use a signal receiver to trace the pipe's route, marking it on the surface and recording the depth at regular intervals.

Practical steps to a reliable outcome
You receive an accurate drainage plan showing pipe routes, depths, and connections overlaid on a property plan. This information is invaluable for architects, builders, and planners, and can prevent costly damage to drains during construction work.
What drives programme and budget
Cost and complexity usually depend on access constraints, total scope, existing condition, and whether related works need to be coordinated in the same programme window.
