Drainage engineers based at Lanes’ depot in Chester are working for the Merseylink Civil Contractors Joint Venture, the joint venture of FCC, Kier, and Samsung that is building the £600m cable stayed bridge. The crossing is scheduled to open in autumn 2017.
Lanes Group has been contracted to provide a range of services, including CCTV drainage surveys, drainage cleaning and unblocking, and remedial work on existing and new drainage infrastructure. Thousands of metres of concrete, plastic, and clay drainage pipes, from 100mm in diameter upwards, will be cleaned over the contract period.
It is using a truck-mounted JHL Recycler jet vacuumation tanker, made by Denmark’s J Hvidtved Larsen, to carry out the pipe cleaning work. This vehicle can filter and reuse dirty water, reducing the need to leave site to refill its water tank.
Mainline CCTV drainage camera teams will carry out surveys of the existing and newly-installed drainage system supporting the road development, using a range of techniques, including using robotic crawler camera.
