This document summarizes best practices for financing water management presented at a ministerial forum in Guadeloupe. It discusses water as both an economic and social good, and the challenges of financing its infrastructure and recurrent costs. Sources of financing include tariffs, taxes, loans, and bonds. While cost recovery is ideal, political and social factors often prevent full tariff-based financing. Effective financial management, revenue collection, and regulatory frameworks are keys to sustainable water infrastructure development. Governance models of utilities may also impact their ability to succeed financially.
