Drain Technology use STC25 Manhole Survey reports which allows us to record details of a manhole's structure and condition, diameter of pipe inlets and outlets, depth of inverts and cover conditions. The record card also gives photographs of the cover, location and internal view.
In addition. we offer GPS location reference points using a Netrover located above an individual manhole, which can then be added to a topographical drawing at a later stage.
While a manhole survey is different from a drainage survey, if carried out in conjunction with the CCTV drainage survey, it gives you a full in-depth overview of the full drainage system by way of two specific and detailed reports.
We cover Oxfordshire, Wiltshire, Gloucestershire, Northamptonshire, Warwickshire, Berkshire, Hampshire, Surrey, London, Hertfordshire, West Midlands and Bedfordshire.
