Screening Tool for Energy Evaluation of Projects: A Reference Guide for Assessing Water Supply and Wastewater Treatment Systems

Abstract

Water supply and wastewater treatment services are basic but critical utilities that have major roles in supporting social and domestic needs of people, sustaining local economic activities, and ensuring healthy urban environments. By 2050, about 65% of the population in Asia and the Pacific are expected to live in cities. This dictates the need to increase access to water supply and wastewater management services. The increase in service coverage would also translate to additional investments by water utility operators, which will lead to increased energy demand in their operations. This means energy management should be incorporated into the designs of urban water supply and wastewater utility investments to ensure optimal operations.
