BACKGROUND The City worked with Akel Engineering Group, Inc. to model the interim water improvements necessary to meet the anticipated peak demand of 25.8 million gallons per day (mgd) by delivering all of the City's water supplied from Zone 7 through the existing turnouts. The modeling identified that three 18- to 24-inch pipe segments (totaling 9,600 feet) and installing a new water turnout and booster station at Turnout 4 would be required. The pressure that pushes the water from Zone 7's line to the City's distribution system at Turnout 4 drops during peak demand periods, reducing the amount of water the City can receive below 1 ,000 gpm and reducing the firm capacity from 4,500 gpm. Zone 7 informed the City that Zone 7 could not increase the pressure of its supply line and that the City would need to install a booster station. A permanent booster station is being designed for the interim water improvements which is anticipated to be in service at the end of 2024. DISCUSSION Rain for Rent is the City's vendor specializing in the rental of temporary pumping equipment and can provide a temporary pump by mid-August; other firms contacted by City staff cannot provide a pump until later this year. While July was unseasonably cool which reduced the demand on the system, it is crucial to have the temporary system in operation before the historical increase in peak demands through September. To ensure the pump can be in place as soon as possible a purchase order was issued for $80,000. The temporary system must be compact enough to fit on the site, maintain access for chemical deliveries, and retain sufficient room to build the permanent station. A diesel pump was selected because the site does not have adequate electrical power to run temporary electric pumps, and the area is too small to install a generator plus the electrical pumps. The diesel pump is housed in a whisper-quiet enclosure to reduce the noise of the pump and motor, which is anticipated to comply with the City's noise ordinance. The amendment to the purchase order will cover the additional rental costs of the system through the end of 2024 when the permanent booster station is anticipated to be in place. The monthly rental is estimated at $10,400 ($166,400 if the pump is used for 16 months) but will be updated based on the actual equipment installed. The cost for the piping, mobilization, and installation will be done on a time and material basis, estimated at approximately $33,600. The City explored purchasing a pump instead of renting, but the lead time is 10-14 weeks, and receiving the necessary air permit for running the generator could take 3-6 months. The Rain for Rent pump is already permitted for use by the Bay Area Air Quality Mangement District. In the event the permanent pump station project becomes delayed, the City will explore whether purchasing a pump will be more cost effective. Page 2 of 3
