Who will manage the whole building and pest inspection process for facing success?

Initially on secondment from The Scottish Office, Duncan officially joined SEPA as East Region senior registrar in 1997.Work started on the restoration in March 1999 and should be complete by Autumn 2001.During the heights of canal-side industry there were no controls for waste disposal so the industrial legacy is a range of pollutants in today’s canal sediments.Dredging” explains Nick Smith, manager of the British Waterways Waste Management Team, “is an essential element of canal management to provide the depth for navigation.In 1992, a British Waterways survey of its 2000 mile canal network revealed that nine kilometres of the Union Canal in Falkirk was heavily contaminated with mercury.

In July 1999 consultation began between British Waterways, SEPA, Scottish Natural Heritage, the local authority and users and neighbours of the canal.In December 1999 a contract was awarded to a joint venture between Shanks Waste Services and canal dredging experts Land and Water Services Ltd.The task to remove 80,000 tonnes of sediment over a 60 week period began in March this year.The material is dredged from the canal by a long reach excavator on a floating pontoon and dropped into a floating hopper which is towed by tug to the treatment site.The wet sediment is treated with lime in a processing plant and the processed sediment left to cure in a bin into a soil-like form.The cured material is transferred in lorries with sealed tailgates and covers and disposed at the Avondale landfill site, where it is contained in a monocell lined with an impermeable triple liner.
