Description:
This report presents cost data for unit processes that are capable of removing contaminants included in the National Interim Primary Drinking Water Regulations. Construction and operation and maintenance cost data are presented for 45 centralized treatment unit processes that are considered to be especially applicable to contaminant removal or to the treatment and disposal of sludges or brines produced by the treatment processes. These cost data are applicable to flows up to 3,785 cu m/day (1 mgd). Cost data are also presented for five point-of-use treatment techniques. Construction and operation and maintenance costs are presented versus the most appropriate design parameter for the process. Construction costs were developed by summing the cost of eight individual categories: excavation and sitework; manufactured equipment; concrete; steel; installation labor; pipe and valves; electrical and instrumentation; and housing. Operation and maintenance requirements were determined individually for three categories: energy (building and process); maintenance material; and labor. All costs are presented in terms of December 1983, dollars, and a discussion is included on cost updating.
