Operation and Maintenance Costs for Municipal Wastewater Facilities

摘要

The report presents the results of the latest and most comprehensive effort to obtain and analyze O&M costs for wastewater treatment works. It summarizes data from more than 900 treatment plants and almost 500 conveyance systems throughout 40 of the 48 contiguous United States, including all ten EPA regions. Included is information on administrative costs, sludge handling costs, and staffing. The basic information for this report was obtained from visits to selected sites, and from earlier studies. This basic information was combined into a simple data base, and examined for relationships between total O&M costs, facility design parameters and plant operation parameters. These relationships were developed for the general national level and, where possible, for smaller geographic units. Where appropriate in analyzing the data, total O&M costs were reduced to their major components.
