Page 4 <br />Community Development Department <br />October 3, 1988 <br />1. Construction of a second water tower. <br />The consultants suggest that it would feasible to consider <br />construction of a small water tower near the intersection <br />of Western and Grandview. The city currently owns a site <br />for the water tower in this vicinity. It is suggested that <br />the tower should be a cylindrical silo, 80 to 120 feet in <br />height. The capacity of the small water tank would be - <br />approximately 250,000 gallons. This tank would be set to <br />match elevations of the existing tank on Fairview. This <br />tank would improve the circulation and pressure problems in <br />the area during the valve closure time by stabilizing the <br />present pressure drops. The estimated cost <br />of this improvement would be $200,000. <br />2. Installation of variable speed pump at booster station. <br />To eliminate some of the pressure fluctuations caused,by <br />opening and closing of the valves at the booster pump <br />station, the consultant suggests that it may be feasible to <br />consider the installation of a variable speed pump. This <br />pump would operate at different speeds at different closure <br />conditions thus providing a more stable system pressure. <br />The existing booster station would have to be modified to <br />facilitate the pump installation. The estimated cost of <br />this variable speed pump is indicated as being $80,000 to <br />$100,000. It was noted by the consultant that a pump of <br />this nature may result in a reduction in electrical <br />efficiency. <br />3. Isolation of low pressure area and in -line booster pumping <br />station. <br />The third alternate to increase the pressure in the <br />Western/Lovell area would involve isolation of the area by <br />installation of additional system valves and construction <br />of an in -line booster pump station to boost the pressure in <br />this area. The preliminary estimates indicate that the <br />cost of a station of this size would be approximately <br />$150,000. Again, the consultant notes that this <br />alternative is somewhat difficult to construct and operate <br />and may not be cost justified because of the minimal <br />improvements to the system pressure. <br />
