Page 3 of 6 lower than the anticipated peak daily demand of 25.8 mgd, attributed to lower temperatures, continued conservation, and modification of the operation of the City’s water system. To meet peak demands without using the wells, the City coordinated with high water users — including the City at its parks and Callippe Preserve Golf Course — to conserve and reduce water usage. To prevent damage to landscaping by greatly reducing water use during the peak demands, landscape areas were watered without conservation when water was available and demand on the system was low. This project combines the remaining two of the three improvements needed to meet this demand. The projects were combined to meet schedule demands and to create staffing efficiencies related to administering a single contract. Staff recommends consolidating the two projects into one and renaming as the Near-Term Water Improvements Project, CIP 24171. DISCUSSION Turnout 4 Replacement and Booster Station and Stoneridge Drive 24-Inch Potable Water Main F-1 Line), CIP No. 24171 On August 15, 2023, the City Council approved and authorized the City Manager to execute a professional services agreement with Woodard & Curran, Inc. for the design of the Turnout 4 Replacement and Booster Station and Stoneridge Drive 24-Inch Potable Water Main (F-1 Line), CIP No. 24171. Turnout 4 is located at the southwest corner of the intersection of Stoneridge Drive and Hopyard Road, and connects to Zone 7’s 20-inch supply line in Hopyard Road. It was built in 1980 with a capacity of 4,500 gallons per minute (gpm). The control and metering equipment are housed below grade in a concrete vault with a small building to house the fluoride chemicals and control systems. The site is shared with a "Welcome to Pleasanton" sign, electrical cabinet, and traffic signal equipment. The turnout operates with higher pressure from Zone 7, pushing water into the City's distribution system. As the Tri-Valley area grew, the available pressure from Zone 7's system decreased when other agencies filled their systems, thus reducing the turnout's capacity to below 1,000 gpm during peak demand. A water booster station is required to ensure the demand can be met regardless of other agencies' activity. The booster station will use electric pumps to pull water from Zone 7's system and increase the pressure to the City's system- desired water-pressure setting, and will be designed to meet the future peak demand of 5,200 gpm. The existing site has minimal space. Staff and the City’s design consultant, Woodard & Curran Inc., are currently developing plans and request for proposals to solicit bids for purchasing a prefabricated booster station (built off-site). This will be placed using a crane as part of the Near-Term Water Improvements Project, thereby limiting the site work to the below-grade piping. During construction, the existing turnout, fluoride system, traffic signal controller, and temporary booster pump will remain in operation. A new 20-inch water line is needed on Stoneridge Drive from Hopyard Road to Johnson Drive approximately 3,500 linear feet) to increase the capacity of the existing 12-inch and 16-inch water lines currently being fed from Turnout 4. The existing 12-inch asbestos concrete pipe built before the 1960s is nearing the end of its useful life and was recommended for replacement as part of the Water System Condition Assessment. As such, the size of the new water line size was increased from 20 inches to 24 inches and will replace the capacity of the 12-inch line when it is decommissioned.
