The ADB Handbook guides the efficient integration of the principles of the World Health Organization (WHO) Guidelines for Drinking-water Quality (2011) (GDWQ), including the Water Safety Framework and the Water Safety Plan (WSP) approach, into Asian Development Bank (ADB) urban water operations.
It has been produced primarily to facilitate compliance of ADB’s urban water projects with global good practice objectives, principles and practices to manage health risks to drinking water consumers.
ADB has a strong interest in ensuring that prolonged and full benefit is realized from its loans in order to maximize their value. In addition, good practice in any urban water project involves having a system in place to ensure that the water supplied remains at the desired quality beyond the initial construction of the capital infrastructure. An important management system approach to helping to achieve this longer-term goal is the WSP.
The implementation of the principles of the GDWQ, including the WSP, is not mandatory for ADB loans. Rather, the principles of the GDWQ as a whole, including the WSP, are considered to represent good practices to be considered and promoted by ADB in providing loans related to urban water infrastructure.
