Since a ROWPU does not operate a full 24 hours, (it is necessary to shut down for 4 hours of PMCS [see Part E:
Preventive Maintenance Requirements]), and since given the conditions of the scenario, one ROWPU produces 1700 GPH.
Thus, one ROWPU operating 20 hours will produce (20 x 1,700 GPH =) 34,000 gallons per day (GPD).
Based on the echelon level in the scenario, the total daily production requirement is 216,000 GPD. Since one ROWPU
produces 34,000 GPD, divide the total daily rate by the production of one ROWPU to determine the total number of
ROWPUs needed for the mission. This would be:
216,000 GPD 34,000 GPD per ROWPU = 6.35 ROWPUs
Round up to the nearest whole number seven (7) as the total number of ROWPUs needed to complete your mission. In the
scenario, you are starting the mission with just four (4) ROWPUs, thus you can only produce (4 x 34,000 GPD =) 136,000
GPD. You are therefore short (216,000 GPD - 136,000 GPD per 4 ROWPUs =) 81,000 GPD. This is the shortfall to be
supplemented by deploying additional equipment and personnel.
Now that you have determined the shortfall, you will coordinate with maintenance support for additional ROWPUs. In
the present instance, you would need three (3) ROWPUs, as well as additional personnel, fuel, and supplies to deploy in
completing your mission.
PART B - MONITORING SAFETY REQUIREMENTS
Monitoring Safety. As a water treatment NCO, you are responsible for monitoring the general safety of the personnel under
your command, the conditions that they are working in, the material they are handling, and the equipment being used. You
will supervise the general, chemical, and personnel safety and monitor smoking hazards during operation of the 3,000-GPH
ROWPU and the OISS.
