The performance of a low pressure pipeline, El Hammami, Egypt
The report describes an investigation into the performance of a low pressure pipeline system, the first introduced into Egypt to serve some 330 ha (780 feddans) at El Hammami, near Cairo. To serve its command area, water must be supplied in rotation between outlets to a large number of small farmers. General lessons and implications for the design and management of systems are drawn.
The report summarises the findings of the hydraulic investigation and observations of the operational practice of the pipeline. Implications for design are then discussed.
Outline guidelines for the design of smaller and simpler pipeline systems at tertiary level are given in an appendix.
