Productivity and Efficiency
According to the U.S. Environmental Protection Agency, water efficiency is the smart use of our water resources through water-saving technologies and simple steps. Using water efficiently will help ensure reliable water supplies today and for future generations. Topics addressed in this theme provide insights, lessons, and guidance on how diverse stakeholders are working to improve water management and reduce water use.

A Technical and Economic Analysis of Low Lift Irrigation Pumping in Egypt
Published:
May 1, 1984U.S. Agency for International DevelopmentColorado State University
The need for small, efficient, low-lift pumping devices is being recognized worldwide. Many developing countries need such pumps to lift irrigation surface water 0.5 to 3 meters. This paper analyzes the technical and economic characteristics of low-lift pumps. Water wheels and both portable and...Read more

Egypt, Arab Rep.Middle East and North AfricaHydraulic Design of a Canal System for Gravity Irrigation
Published:
April 1, 1984U.S. Agency for International DevelopmentColorado State University
Irrigation by gravity from a water delivery system where the difference in elevation between the canal's source and the fields is small requires careful use of the limited head available. Drop structures normally used to control flow are not used in order to conserve head. Instead, a desired...Read more
