5-3 Drinking water system description. The drinking water system provides storage for water produced by the ROWPU system
and discharges it to shore, or another vessel, or for use onboard the barge. The pressure set supplies onboard drinking water to the
reserve tank the dayroom drinking fountain and sink, the shower on the forward deck, the four washdown stations in the ROWPU
space, the chlorination system in void 2 port, and to the washdown station on deckhouse top (Figure 5-1). The system has a total
storage capacity of 15,000 gallons plus 250 gallons reserve and operates in a maximum allowable sea state 3 condition.
