The Impact of the EC Urban Waste Water Treatment Directive

During the last two years significant policy and legislative developments have taken place in the UK and in the EC in respect of sewage treatment and disposal and the dumping of sewage sludge at sea. Details of the UK Government's sewage-treatment initiative and its decision to stop the dumping of sewage sludge at sea by 1998 are described. An outline is given of the provisions of the EC urban waste water treatment Directive, in particular those provisions concerned with sewage treatment, trade effluent discharges from prescribed industrial sectors, and the termination of dumping of sewage sludge at sea. The implications of these developments for Scottish sewerage authorities are summarized and provisional estimated costs of meeting these new obligations are given. The opportunities available to contractors and equipment manufacturers are highlighted.

Treatment and Disposal of Sewage Sludge in the Mid-1990s

The paper reviews the current methods of sludge technology, and compares them with those discussed by Ashton in 1904. The paper also plots the development of some of the current technology over the last century, particularly those methods of treatment which were mentioned by Ashton but were not in existence at the time.
The 1990s have been a most interesting era, and have probably seen more changes in sludge technology than any other decade this century. The most significant impact will be due to the cessation of the sea disposal route which, at the beginning of the 1990s, was used for about 30% of the total sludge production in England and Wales and approximately 76% of the total sludge produced in Scotland.
