<br />, <br /> <br />II <br />II <br />II <br />II <br />II <br />II <br />II <br />II <br /> <br />The original 30" wooden transmission line was also constructed in 1908 and <br /> <br /> <br />ran from the sand settling basins to the treatment plant. Over the last <br /> <br /> <br />20 years the lower 3.6 miles of wooden line have been replaced with steel. <br /> <br /> <br />Over the years short segments of the upper 3.4 miles of the original wooden <br /> <br /> <br />line have been replaced. Photographs of the wooden transmission line taken in <br /> <br /> <br />August, 1972 are shown as Exhibit No.5. <br /> <br />The standby pump station is located below the treatment plant and is supplied <br /> <br /> <br />with water by the Hydraulic Ditch at a point approximately .3 miles from <br /> <br /> <br />the Hydraulic Ditch diversion point on the Arkansas River. Water is delivered <br /> <br /> <br />from the pump station to the treatment plant via a 30" steel line. Exhibit <br /> <br /> <br />No. 7 shows the location of the pump station in relation to the treatment <br /> <br /> <br />plant and Arkansas River. <br /> <br />Adequacy and Improvements Required ~n Existing Facilities. <br /> <br />II <br /> <br />The existing intake facilities do pfesent problems in the winter months. <br /> <br /> <br />Ice buildup occurs and at times dyn~mite must be used to free the jams. <br /> <br /> <br />Also there are some problems with ~cessive amounts of silt being transported <br /> <br /> <br />to the treatment plant via the raw vater line. A recent inspection by City <br /> <br /> <br />employees of the 40" steel line betveen the intake basins and sand settling <br /> <br /> <br />basins indicated it is in extremely poor condition with numerous holes in <br /> <br /> <br />the bottom of pipe. <br /> <br />II <br /> <br />II <br />II <br />II <br />LI <br />rl <br />II <br />II <br />J <br />I <br /> <br />If these intake facilities are to be used on a continuing basis in future <br /> <br /> <br />years the 40" line between the intake and sand settling basin must be replaced <br /> <br /> <br />and possibly modifications to the intake basin construct~d to eliminate the <br /> <br /> <br />ice and silt problems and to eliminate manning the intake facilities on a <br /> <br /> <br />full time basis. An estimate has been prepared for replacing the 40" line, <br /> <br /> <br />but additional research would be required to recommend modifications necessary <br /> <br /> <br />at the intake to fully eliminate the ice and silt problems. For developing <br /> <br /> <br />forecasts of capital expenditures required for continuing to use the present <br /> <br /> <br />method of raw water supply, no capital costs were included for modifying <br /> <br /> <br />the intake facilities. <br /> <br />The raw water transmission line is a continuing source of maintenance problems. <br /> <br /> <br />The upper 3.4 miles of wooden line i5 in poor condition in many places. <br /> <br />3-2 <br />
