The Small Piped Water Network (SPWN) tool kit was conceived and developed as a result of the lessons and experiences of the Asian Development Bank regional technical assistance: Implementing Pilot Projects for Small Piped Water Networks, as well as the experiences of professionals and development agencies implementing similar projects. The tool kit is intended to be
used as a guide for governments, development agencies, water utilities, and civil society in designing or implementing projects using the SPWN concept for urban poor or rural
communities without access to piped water systems.
