5.1.2.1 Location

5.1.2.1.1 Polluted Harbors (03 C)
A reverse osmosis unit, distillation plant, or other process that
supplies water to the vessel’s POTABLE WATER system must
only operate while the vessel is MAKING WAY. These processes
must not operate in polluted areas, HARBORS, or at anchor.

5.1.2.1.2 Technical Water
A reverse osmosis unit or evaporator with a completely
separate plant/process, piping system, and connections from
the POTABLE WATER system may be used to produce
TECHNICAL WATER while in polluted areas, HARBORS, at
anchor, or while not MAKING WAY.

5.1.2.1.3 Onboard Water Sources
Onboard water sources such as TECHNICAL WATER, air
conditioning condensate, or wastewater of any kind (treated or
untreated) are not allowed for POTABLE WATER production.

5.2 Bunkering and Production Halogenation and pH Control

5.2.1 Procedures

5.2.1.1 Residual Halogen and pH

5.2.1.1.1 Halogen and pH Level (03 C)
POTABLE WATER must be continuously halogenated to at least
2.0 MG/L (ppm) free residual HALOGEN at the time of bunkering
or production with an automatic halogenation device. Adjust the
pH so it does not exceed 7.8.

The amount of HALOGEN injected during bunkering or
production must be controlled by a flow meter or a free
HALOGEN analyzer.
