Inter-departmental coordination. Public agencies can improve the coordination of policy targets and methods to ensure that public goals regarding wastewater management are achieved. For example, coordination among the ministries of agriculture, water resources, public health, and economic development is needed to ensure that the goals and programs of one agency are not in conflict with the goals and programs of another. The total cost of achieving public goals will be minimized with effective inter-ministry coordination (Qadir et al., 2007).
