is related to other part(s) 3350167 Estimating water treatment costs, volume 2 : Cost curves applicable to 1 to 200 mgd treatment plants
This report discusses unit processes and combinations of unit processes that are
capable of removing contaminants included in the National Interim Primary Drinking
Water Regulations. Construction and operation and maintenance cost curves are
presented for 99 unit processes that are considered to be especially applicable to
contaminant removal. The report is divided into four volumes. Volume 1 is a summary
volume. Volume 2 presents c.ost curves applicable to large water supply systems with
treatment capacities between 1 and 200 mgd, as well as information on virus and
asbestos removal. Volume 3 includes cost curves applicable to flows of 2,500 gpd to
1 mgd. And Volume 4 is a computer program user's manual for the curves included in
the report. For each unit process included in this report, conceptual designs were
formulated, and construction costs were then developed using the conceptual designs. The construction cost curves were checked for accuracy by a second consulting engineering firm, Zurheide-Herrmann, Inc., using cost-estimating techniques similar to those used by general contractors in preparing their bids. Operation and maintenance requirements were determined individually for three categories: Energy, maintenance material, and labor. Energy requirements for the building and the process are presented separately. Costs are in October 1978 dollars.
