This manual on Improving Transparency, Integrity, and Accountability in Water Supply and Sanitation is the result of a partnership between the World Bank Institute (WBI) and Transparency International (TI).

It was developed under the Open and Participatory Government Program at the Municipal Level (known by its Spanish acronym as the GAP Municipal Program). The GAP Municipal Program, managed by WBI since 2000, supports institutional change in local government by helping to design tools to combat corruption. It provides a platform for disseminating knowledge on anticorruption strategies that can be adapted and used by national agencies and municipalities worldwide. Over the years, GAP has supported many training initiatives in Latin America and the Caribbean and in Anglophone and Francophone Africa.
