Cairo Sludge Disposal Study

This paper describes the establishment of the Cairo sludge disposal study which is being funded within the Mediterranean Environmental Technical Assistance Programme through the European Investment Bank and promoted by the Cairo Wastewater Organization. The study is a demonstration programme to show how the problems of sludge disposal from large, rapidly developing cities, such as Cairo, can be solved through the establishment of a practical system for the safe re‐use of sewage sludge in agriculture. It is being carried out principally through a series of demonstration field trials and the development of ettensive information. This study is of relevance to Egypt and other countries with similar agricultural and environmental conditions, where (a) sludge production is increasing, (b) water protection is essential, and (c) appropriate environmentally acceptable solutions are urgently required.
