Measures to improve efficiency: Technological options

Improving WUE is a critical aspect of comprehensive water resources management. Technological options include use of better technologies and improvements in management skills. A study carried out by OED and AGR (Plusquellec, 1990) found that, despite the extent and range of Bank investment in the water sector, little analysis had been undertaken to compare the efficiency of alternative engineering approaches. The following section focuses on the technological aspects of improving water use efficiency, which consist of preventing losses and promoting reuse. Both efforts increase the availability of water at user levels.
