EA Bedford contacted ADC

ADC were contacted by the Environment Agencies' Bedford office with a project that had numerous problems to solve. The project was to de-silt an area of river at Thornborough Mill in Buckinghamshire.

Site problems to solve

The very old bridge had a weight restriction and overhead power lines restricted access, making it impossible to dredge and de-silt safely by conventional means using an excavator. On top of this a power cable had been laid below the river bed.

The Silt Pusher makes light work

Using the Silt Pusher we could move the silt to a position where the we could safely and efficiently use our pumps to remove it.

Dewatering reduces waste by 75%

Then using our high-tech dewatering rig we could return the water and take the dry 'caked' waste to an approved local waste site for disposal. The waste was reduced by 75% using this process minimising transportation and waste costs.

Beauty spot preservered

Thornbourgh Mill is a grade II listed building surrounded by picturesque countryside so it was imperative the waste was removed and the nature preserved.

Clients very impressed

"The whole project went very well, was closely managed and from setup to completion took 8 days" quoted Mike Reeve.
