Architect and Associates <br /> 979 F Street, Suite A <br /> Davis, CA 95616 <br /> SUBJECT: PRELIMINARY ENGINEERING; ONSITE DOMESTIC WATER AND <br /> WASTEWATER SYSTEMS; ACAMPO <br /> Dear Mr. Moore: <br /> This letter summarizes the basic design criteria for the proposed domestic onsite water <br /> and wastewater systems for the Acampo Project. <br /> PROJECT INFORMATION <br /> Design Population: 400 single men; 400 bedrooms <br /> Site Area: 20 acres <br /> Public Utilities: No public water or wastewater utility service is available <br /> WATER SYSTEM <br /> Descrlpt}on. The proposed onsite domestic water system would consist of: <br /> 1. an onsite well; <br /> 2. an:onsite ground storage tank; <br /> 3. domestic booster pumps through a hydropheumatic tank to the distribution <br /> system; and <br /> 4. fire booster pump(s) for hydrant flow and building sprinkler systems. <br /> The capacity of the well will be greater than the average daily demand, about 75 gallons <br /> per minute. The storage tank will supply the peak hour and peak day water supply. <br /> Duplex alternating domestic booster pumps are proposed; with one pump safely <br /> providing the average demand (100 gpm), and both pumps providing the peak hour <br /> demand (200 gpm). <br /> 6700 FREEPORT BLVD., SUITE 202 • SACRAMENTO.
