The way water levels are determined, is by measuring the pressure at the bottom of the tank, and then converting that number (which is given in PSI, pounds per square inch) to a height. Water levels are critically important for water management organizations because the utility is required to maintain a certain amount of water in reservoirs at ...

Raw water is supplied to the system by three (3) 300 GPM @ 65 PSI well pumps pumping from 6 inch casings 600 feet deep with 20 feet long 6 inch screens. The pumps are automatically started and stopped by level control on an elevated 150,000 gallons storage tank. The elevation of the tank maintains 42 to 50 PSI on the distribution system.
