While Minnehaha Community Water Corporation (MCWC) prepared for their third and final Lewis & Clark Regional Water System (L&C) connection in the southeast portion of their distribution system, it was determined that the area would use significantly less water than their original 1.1 million gallon per day (MGD) allocation. MCWC tasked Banner with determining a way to use more L&C water from the east connection. Since the east L&C connection was made in the lowest hydraulic grade line (HGL) service area in the system, water would need to be pumped north into a higher HGL service area. An existing control valve vault site was chosen as the location for the new booster since the existing control valve was not needed in the system. The booster station is equipped with two 50 Hp end suction pumps, with provisions for a future third pump. The booster station capacity is 750 gallons per minute (GPM), and could increase to 1,000 GPM with a third pump. A unique feature of the booster station is a reverse flow control valve, which allows MCWC operations staff to gravity flow water south in the event of an emergency in the L&C system.
