Waste Water System

The waste water system in your Oliver can be described as two separate
systems; a gray water system that consists of the drain lines and holding tank
for waste water from the sinks and shower and a black water system which
includes the holding tank and drain for toilet wastes. Each system is self-
contained, and allows disposal of the wastewater at designated dump
stations.
The gray water system has drain traps. Both tanks are vented to equalize air
pressure and disperse odors caused by drain water and waste. Sometimes
stop and go while driving may empty the drain traps of water and allow the
odors of the gray water tank to come into the coach. Residue in the drain
water lines also can produce odors. To combat gray water holding tank odor,
an approved deodorizing agent should be used. An agent that dissolves
grease and fats and contains a detergent will help keep tank and drain lines
clean and free flowing.
Holding Tanks
The Oliver Travel Trailers holding tanks hold 32.5 gallons in the grey tank
and 18.5 gallons in the black tank. Each tank has a separate drain line and
dump valve, which permits dumping tanks individually. Each tank should be
emptied often at a dump station designated for this purpose. Most national
state and private campgrounds have dumping facilities. Many service
stations, particularly along interstate highways, also have these facilities and
list dumping station locations across the nation.
