A pipeline on a straightened alignment <br />would require the acquisition of additional right-of-way, <br />The proposed pipeline route would follow the alignment of <br />First Street, which has not been cut through. There would <br />be some expense for right-of-way purchase. <br />All of the alternativ$ for reduction of seepage loss <br />from the canal will require the replacement of nine lateral <br />turnouts with measuring devices and four individual turn- <br />outs to shareholders. The laterals range in size from 8- <br />inch to 24-inch pipes and the minimum recommended size to <br />be installed for laterals is 12-inch. There is a need in <br />the east end of the upper canal to be able to turn out more <br />water for delivery to the lower canal, The first four <br />laterals can only carry a total of about 10 cfs at present, <br />instead of approximately 16 cfs needed, <br />The first alternative repair method is to place a <br />concrete lining in or next to the existing ditch. The first <br />700 feet of existing lined ditch would be repaired. The <br />next 8,800 feet of ditch would be constructed with a ]-inch <br />thick lining with a ]-foot bottom width and l-to-l sides, <br />three feet deep. The remaining 10,650 feet would have a <br />similar bottom-width linin& but only 2~ feet deep, <br />The second alternative repair method is to repair the <br />first 700 feet of existing lining and extend the lining <br />another 600 feet. At that point, the water would enter a <br />42-inch concrete pipe and run due west for ],890 feet to <br />the present box culvert under Highway 115. On the west <br />side of the culvert, the pipeline would run 2,110 feet <br />L <br />directly to the intake of Penrose Water district. This <br />route is 2,200 feet shorter {han the present canal align- <br />ment. From the water district intake, the remaining <br />10,650 feet of canal would be placed into a ]6-inch con- <br />crete pipe, which would carry from ]6 cfs to 25 cfs as the <br />gradient reduced at station t45. <br />The third alternative repair method is to repair the <br />700 feet of existing lining ~nd extend it another 600 feet, <br />
