FM Conway will use Specialist CCTV equipment to map the 117 mile route of the M25’s extensive draining network.
The £300,000 drainage mapping contract secured by FM Conway includes plotting the overground and underground drains using CCTV, along the route of the M25. The results will contribute towards the national HADDMS (Highway’s Agency Drainage Data Management Systems) survey,
The survey is being used to collate, manage and store drainage information for the strategic road network. Data will be gathered of manhole covers, gullies and culverts using hand held GPS devices which will show planners where existing tunnels are in order to plan for highways construction and lane widening projects.
To minimise disruption to road users, all HADDMS surveys are carried out during the night time, helping to limit road closures and traffic management operations during busy daylight hours. FM Conway has previously been involved with conducting HADDMS surveys across the country and has invested in five CCTV vans, costing £120,000 each.
Working in two man teams, the CCTV van’s crew insert devices into the drains which are capable of driving through the underground pipes, filming any pathways and obstructions on video and recording the data on a DVD.
Tristan Miles, Director of Cleansing at FM Conway, said: “The award of this new contract further outlines our strength and capabilities within the market place.
“It also demonstrates our intentions to develop our technical abilities within the industry and we are able to supply a great service at very competitive prices”.
The system will also form a crucial element of response in the event of fuel and liquid spillages on the nation’s highways. HADDMS will allow responders to effectively manage such incidents by providing information on spillage routes from road to outfall.
It will now be possible for the emergency services to trace the path of liquids from the spillage to a waterway and inform responders of any interception methods or other measures that may be used to contain the pollutant, before it can cause serious environmental damage.
The contract was awarded by Connect Plus Services.
