BACKGROUND <br /> The Operations Services Department is responsible for exercising, maintaining, and <br /> repairing the 9,800 valves in the City's water system. These valves are the only way <br /> staff can control the water system in the event of breakages, water quality events and <br /> system zoning. These valves can range from new to 50 years old, and sizes of 3 inches <br /> to 24 inches. Many of the larger valves cannot be operated manually without risk of <br /> injury to staff or simply require strong mechanical force. The hydraulic valve operator <br /> overcomes these issues and allows staff to operate the largest and most difficult valves <br /> to control the water system during normal operations and even more so during an <br /> emergency. <br /> In addition, accessing the valve control stem regularly requires staff to perform a <br /> vacuuming/cleaning process to find the valve control. The current process requires <br /> using a hydro excavator— a separate piece of equipment— to vacuum and clean the <br /> valve access before the valves can be operated; the cleaning takes significant time and <br /> keeps the hydro excavation crew from other work. The new hydraulic valve operator <br /> and chassis come equipped with a positive displacement vacuum system and a 250- <br /> gallon debris tank. The addition of the vacuum system will enable staff to complete the <br /> field task with one piece of equipment and a one crew. The valve operating truck also <br /> mitigates back injuries that come with the straining associated with operating older and <br /> larger valves. <br /> The current unit (Unit #317) is a 1990 hydraulic valve operator on a 2003 Ford F350 <br /> chassis with 81,000 miles of use. The normal useful life of a hydraulic valve operator is <br /> 15 years; as such, this unit has experienced a variety of mechanical issues <br /> necessitating $40,133 in maintenance costs to date. <br /> DISCUSSION <br /> In preparation for this purchase, the City contacted Sourcewell, formerly known as <br /> National Joint Powers Association (NJPA), which was established with the statutory <br /> purpose to assist public agencies in meeting specific needs which are more efficiently <br /> delivered cooperatively than by an entity individually. Sourcewell clients can utilize <br /> cooperative purchasing contracts through similar joint powers, intergovernmental <br /> cooperation, or cooperative purchasing laws in their respective jurisdiction. Participating <br /> agencies include all eligible government, education, and nonprofit agencies nationwide <br /> and in Canada. This purchasing method complies with the City's Purchasing Policy. <br /> The purchase of the valve operating truck is recommended through the Sourcewell <br /> Contract#091521-NAF with National Auto Fleet Group. The purchase price is $251,386 <br /> including delivery and taxes; adding a 15 percent contingency of$37,708 brings the <br /> total to $289,094. <br /> Page 2 of 3 <br />
