U.S. Forest Semce,property immediately <br />adjacent to, and west of, the existing water treatment plant property. Two, OIr <br />tions of building a dam across the valley to create a reservoir were consider- <br />ed, one using imported materials which would result in a storage capacity of <br />approximately 30 acre/feet, and the other using on-site materials resulting in a <br />. capacity of approximately 45 acre/feet. <br /> <br />A'raw water pump station would divert water from the River at the same 10- <br />cation as the existing inifltration gallery divertS water to the existing plant, <br />and would convey' it to the above reservoir site via a common fill and draw <br />line when the River is running,and which would also be used to return stored <br />water from the reservoir to the plant during times of drought when the River <br />has run dry. . <br /> <br />The upgrade of the water treatment plant would be identical to that in Alter- <br />nate "A"., whereby a new micro-fIltration unit of the same capacity as the ex- <br />isting unit will be placed adjacent to the existing unit . <br /> <br />ALTERNATE "D" -RESERVOIRS WITIllN LOCAL SWALES AND UP- <br />GRADE OF 1HE EXISTING WATER TREATMENT PLAm <br /> <br />D-l Lot 5-11th Filing <br /> <br />lbis site is on private property on which a 20 acre/foot reservoir had at one <br />. time been proposed. This site is not being prioritized by the District at this <br />time because of the large negative impact it would have on this property. <br /> <br />D-2-Crow Lane Reservoirs' <br /> <br />As indicated in the Planning Document, there were two reservoir sites identi- <br />fied in the natural swale between Crow Lane and Highway 36, both on private <br />property. A raw water pump station would be required at the existing treat- <br />ment plant site, as well as a common fill and draw line, to deliver water to the <br />reservoir sites when the River is running, and to return stored water to the <br />plant when the River is dry, similar in concept to the earlier described Maure <br />13 <br />
