WASTE WATER SYSTEM
(Holding Tanks)
The drainage system is self-contained and
uses two separate holding tanks to contain the
waste water until it can be dumped at an
appropriate waste water disposal site. This means
you can use the toilet, sinks, and shower even in
areas where utility hookups are not available.
The black water holding tank contains the
sewage from the toilet and may include bathroom
lavatory on some models. The gray water holding
tank contains the waste water from the galley
sink and shower, and may include bathroom
lavatory.
See “Specifications” in
Section 1–
