Drain Mapping

Drain mapping creates a complete, accurate plan of your property's drainage system — showing every pipe run, manhole, connection, and outlet. It's essential for property management, building projects, and resolving drainage responsibility disputes.

What to Look For

  • Property has no existing drainage plans
  • Multiple building extensions over the years
  • Disputes about drainage responsibility with neighbours
  • Required for facilities management of commercial properties
  • Needed for planning applications and building regulations

How We Diagnose the Problem

We combine CCTV surveys with drain tracing technology to map every pipe run, junction, and connection in your system. We record pipe diameters, materials, depths, and flow directions, and identify which pipes are private and which are public.

Think you might have drain mapping? A professional inspection will confirm the diagnosis.

How We Fix It

The completed drain map is a scaled, annotated plan of your entire drainage system, suitable for architects, planners, and building control. We provide both digital and paper copies, and can overlay the drainage plan onto OS maps or site plans.
