B-2 Major components. The ROWPU System consists of two identical units, ROWPU 1 and ROWPU 2. Each unit
includes a pretreatment skid assembly consisting of a control station, two chemical metering pumps, four water pressure
gauges and a cartridge filter. It also includes a steel framework to support these components as well as the necessary
electrical cabling switches, indicators, plus interconnecting piping and valves. Seawater pumps, components of the
seawater system, provide pressure for the ROWPU system.
B-3 ROWPU system description. The ROWPU system processes sea water or brackish water supplied by the seawater
system to create drinking water. Chlorine is added to the processed water by the chlorination system. The resulting
drinking water is then discharged into four drinking water storage tanks.
