1-8 Capabilities. The total onboard storage capacity Is 15,000 gallons plus 250 gallons reserve. The maximum
discharge pressure is 140 pounds per square inch (psi) and the maximum discharge rate with both ROWPU's operating
Is 300,000 gallons per day (gpd), 15,000 gallons per hour (gph), or 250 gallons per minute (gpm).
1-9 Limitations. The drinking water system shall not be operated in rough sea conditions exceeding Sea State 3. For
acceptable drinking water standards, the chlorine content must be from 5 to 7 parts per million (ppm) and the salinity
level must not be greater than 1500 ppm
