Drain Mapping in Loughborough

What the work involves

• CCTV tracing with sonde location of each run from the surface
• Every chamber lifted, measured and logged
• Flow direction, pipe sizes, materials and depths recorded
• A scaled site plan of the complete system

When you need it

• A build-over agreement or extension near assumed sewer routes
• A site purchase where records are missing
• Recurring problems nobody can trace to a source
• Separating or verifying foul vs surface water connections

What drain mapping costs in Loughborough

Domestic mapping surveys typically run £150–£450 depending on the size and complexity of the system — camera tracing plus sonde location, producing a scaled plan (typically CAD-drawn, delivered as a PDF) rather than just footage.

What the map shows

• Every run, chamber and connection, with depths
• What serves what — and what is redundant
• Where the system meets the public sewer — and where ownership changes from private to the water company’s
• Flow proven by dye tracing — separate colours dropped at each outlet, flushed clean between tests, confirming which run serves what and catching misconnections

Deeds rarely show private drainage accurately; mapping surveys reality, which is why extensions, purchases and build-over applications all start here.

Drain Mapping in Loughborough — common questions

Is this the same as a CCTV survey?

A survey grades condition; mapping records geography. They're usually done together — one crew, one visit, two documents.

Are my drains not on the property deeds?

Rarely accurately — deeds seldom show private drainage, and public records improve but do not cover laterals. Mapping is how you get the true picture — worth reconciling against the water company’s own sewer records, which anyone can request.

Do I need mapping before an extension?

If any drainage might sit under or near the footprint, yes — it is the cheapest item on the whole project and de-risks the most. And where a planning condition asks for drainage details, the mapped plan is what discharges it.

What is a build-over agreement?

Building over or within 3 metres of a public sewer needs Severn Trent Water's agreement first — and an accurate plan of the affected runs is the first thing they ask for.
