Economic issues in the design and analysis of a wastewater treatment project. 6 6 - - - - - - - - ERD Technical Note Series. . - . - 0 . - . - 0 .

ABSTRACT : A wastewater treatment plant is often planned as one small part in a greater system to manage ambient water quality. Indeed, that is probably the best role for wastewater treatment, since the benefits of treatment are not secured unless all current and future pollution sources nearby are also controlled. When a comprehensive and effective system for managing water quality is in place, economic analysis of an individual treatment plant will not reveal the full motivation or justification for a plant. Instead, economic analysis should focus first on the greater system to manage water quality. If the system as a whole is economically justified, then any constraint imposed on an individual project can be taken as given. This paper discusses one common approach to public management of surface water quality, and the design and analysis of a wastewater treatment project within that management framework.
