摘要

The purpose of this report is to present the results and analyses of the most comprehensive survey made to date on the operations and maintenance (O&M) costs of the Nation's municipal wastewater treatment plants and collection systems. The results have been derived from actual plant operating records across the continental United States. Costs are presented for different levels of wastewater treatment,types of plants and collection systems,and segregated cost categories. A number of analyses are also presented as relative costs for certain treatment variables and characteristics. The cost data utilized in the study range from fourth quarter 1972to first quarter 1977. All costs have been adjusted to third quarter 1977dollars. Only treatment plants of 1.0million gallons per day (mgd) capacity or larger were sampled in this survey. The analyses in this study were performed with the assistance of a computer statistical package.
