When carrying our large site drainage surveys, quite often there are drains that are not shown on the drawings supplied or there is just not enough information on where the drain outfalls are. The difficulty in obtaining this information is that nothing is visible. This occurs frequently on sites where the drainage system has been altered and been added to over the years. The below diagram shows that by using a specific digital locator we can detect and trace the drain precisely. The sonde which emits the frequency can also be used in tandem with a video camera to enable visual inspection.
This information can then be added to the supplied drawing giving a complete true layout of the drainage system.
We cover Oxfordshire, Wiltshire, Gloucestershire, Northamptonshire, Warwickshire, Berkshire, Hampshire, Surrey, London, Hertfordshire, West Midlands and Bedfordshire.
