Notes:
(1) Include salt water for fire fighting and cooling/flushing when potential exists for ship to
be in cold iron status. Total demand equals fire fighting plus cooling/flushing flow.
(2) Supplemental 480 V service is recommended on all CVN piers for use by other classes of
ships.
(3) There are two types of CVN sanitary sewage systems. CVN 68-71 has 7 tanks with 3
manifold discharge stations. Each station has 2-400 gpm pumps. CVN 72-76 has 2 tanks
with 2 discharge stations. Each station has 2-400 gpm pumps.
(4) Peak demand assumes emptying an 80,000 gallon shipboard oily waste holding tank
(OWHT) at arrival.
(5) For multiple CVN's at the pier, contact the NAVFAC Criteria Office for diversity factors
for each utility system.
