What a Drain Mapping Survey Includes
- 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
Survey Methodology
We employ a range of non-destructive techniques to accurately map underground drainage networks. This includes high-resolution CCTV crawler cameras and sonde tracing, where transmitters are pushed through pipes and detected at ground level to confirm precise alignments. These methods allow us to produce highly accurate survey data without the need for excavation.
CAD and Drawing Deliverables
- 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
When Drain Mapping Is Required
- 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
Survey Limitations and Access Requirements
It is important to note that survey results are dependent on access and site conditions. Elements that are inaccessible, submerged under high water levels, or composed of untraceable materials may limit the results of the survey. The survey does not promise a complete detection of all underground assets where environmental or structural conditions prevent equipment passage or signal transmission. Safe access to all chambers and outfalls must be provided to ensure the most comprehensive results possible.
