Drain Mapping & Drainage Mapping Surveys UK
Drain mapping surveys record the layout of accessible foul and surface-water drainage networks. Survey X combines chamber measurements, CCTV inspection and sonde tracing where required to produce CAD drainage plans for design, redevelopment and asset management.

What a Drain Mapping Survey Records
- CCTV inspection and internal pipe condition assessment
- Manhole inspections and detailed manhole schedules
- Topographical pickup of drainage assets
- Determination of pipe routes and flow direction
- Measurement of pipe diameter (where accessible)
- Recording of invert and cover levels (where scoped)
- Identification of connections, outfalls and chambers
- Reporting of observed defects and structural issues
CCTV Drain Mapping & Sonde Tracing
A drainage mapping survey combines accessible chamber measurements with CCTV inspection and sonde tracing where required. CCTV records visible pipe condition and connections; a sonde helps trace routes from the surface. Agreed survey control relates recorded assets to your CAD plan. Untraced sections, assumed connections and access restrictions should be clearly distinguished from confirmed survey findings.
Drainage CAD & DWG Plans
- CAD/DWG files for seamless integration into project designs
- Detailed PDF plans and sections
- Surveys related to agreed coordinate systems (OSGB36 or local)
- Comprehensive manhole schedules and CCTV survey reports
Drainage Mapping for Development & Construction
- Design of new drainage connections and capacity upgrades
- Effective asset management and long-term maintenance planning
- Redevelopment of brownfield sites where existing infrastructure is unknown
- Formulating a robust drainage strategy for planning applications
- Build-over agreements and infrastructure easements
How Accurate Is Drain Mapping?
Drain mapping accuracy depends on access, survey control and the methods used. Chamber measurements and traced routes are recorded alongside relevant limitations. Blockages, high water levels, inaccessible chambers and signal interference can prevent parts of a network being confirmed. Our plans distinguish confirmed routes from assumed connections and untraced sections. Tell us your required coordinate system, level datum and drawing detail when requesting a quote.
