Improving Life for the Poor Through Water Supply and Sanitation

Abstract

This summary of evaluation studies in the water supply and sanitation sector is the fourth in the Assessing Development Impact (ADI) Series of the Operations Evaluation Department (OED) of the Asian Development Bank (ADB). It presents the major findings, lessons, issues, and conclusions of OED’s recent studies and reports in the sector. Water supply and sanitation alone accounted for $4 billion, equivalent to 5 percent of total lending, as of December 2000. Most of this assistance has been for the construction of water source pumping facilities, treatment plants, booster pumps, reservoirs, and/or main and distribution pipelines. There has also been technical assistance of almost $65 million for preparation of projects and strengthening the local agencies that run the water services.
