Comprehensive and accurate sewer records are essential to allow Water Companies and their agents to perform their Statutory obligations. In addition, the accuracy of drainage area studies or the trouble shooting of sewerage problems, however large or small, is ultimately dependent on the accuracy of the base site data.

Indepth Surveys offers specialist services in manhole and impermeable area surveys with the necessary site and office quality control procedures for the production of reliable data. The services we can offer are as follows:-

• Digitising and referencing of existing sewer plans to STC25 format.
• Computer validation of existing manhole records to check for completeness and inconsistencies.
• Full manhole surveys to STC25 standard including the production of sewer records and plans both hard copy and digitised to the clients specification.
• Impermeable area surveys of a full area or a sample of that area, with the production of coloured plans to the clients specification.

We are pleased to quote for surveys of any size at any location as an isolated activity in itself or as an integrated part of a complete Drainage Area Study.
