12.2.1 GREY WATER - WASTE
HOLDING TANK
The drainage from the kitchen sinks, bathtub and
shower pan is collected in a separate grey water
holding tank. This tank has its own dump valve but
ties into the same termination valve outlet as the
waste holding tank.

after draining the waste holding tank. This will help
flush solids out of the sewer hose.
12.2.2 BLACK WATER - WASTE
HOLDING TANK
The black water holding tank collects all the waste
from the toilet and vanity sink. Before using your
waste holding tank, deoderize it by adding one
gallon water and a commercial holding tank
deoderizer through the toilet.

If grey water holding tank is allowed to
