A challenge in the coming years will be to ensure that federal and state programming adhere to that prioritisation. In the case of water supply and sanitation programmes, conditions to receive support include the existence of a formal agreement between the state and federal governments for joint action, and to present an annual programme approved by the State Committee for Planning and Development (COPLADE) or the state-level organism in charge of water supply and sanitation planning. Subsidies for wastewater treatment activities must be first applied to ensure that supported wastewater treatment plants operate at a minimum of 90% before they can be applied to other investments.
