Ensuring optimal operation of existing water projects in water investment strategy

This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities. Agenda 21 recommends that the setting of fresh priorities for private and public investment strategy should, among other factors, take into account maximum utilization of existing projects, through maintenance, rehabilitation and optimal operation.
