What a Manhole Survey Records

Chamber reference and location
Cover type, condition and level
Invert levels (where safely accessible)
Pipe sizes and flow direction
Materials (where observable)
Connecting pipes and chamber dimensions
Observed defects and photographs
Coordinates for mapping integration

Manhole records support drain mapping surveys by documenting accessible chambers, levels and connections.

Survey Methodology

Manhole Schedule Deliverables

Chambers are inspected from a safe, accessible position at ground level. This process involves lifting the cover and using specialist equipment to record internal dimensions, invert levels, and pipe configurations. For more complex structures or where internal physical access is needed, a separately planned confined-space entry may be required.

When Manhole Surveys Are Required

Manhole surveys support drainage design and asset management. Where connections or buried routes need investigation, drain and sonde tracing can extend the survey scope.

Access, Safety and Survey Limitations

Ground level inspections only (unless confined-space entry scoped)
Locked, buried or inaccessible covers
Flooding or debris obscuring invert levels
Unsafe structural conditions
Restricted site access
