The Management of Potable Water Treatment Sludge: Present Situation in the UK

This paper details the results of a survey of UK potable water supply organisations, which was undertaken in 1998 on behalf of UK Water Industry Research. An extrapolation of the data indicated that, in 1997, about 131 000 tDS of water-treatment works sludge were produced in the UK. The relevant methods and associated costs are reported. A number of companies are using, or developing, novel waste-management methods for water-treatment works sludges, such as incorporation into bricks and spreading on agricultural land, and these are discussed.
