PRESIDIO
The waste water system in the motorhome can be described as two separate systems. A gray
water system that consist of the drain lines and holding tank for waste water from the sink and
tub, and a black water system which includes the holding tank and drain for toilet waste.
In some cases the bathroom lavatory may drain into the black tank. Each system is self
contained, and allows disposal of waste at designated dump stations at your convenience.
Components of the gray water system have drain traps, and both tanks are vented to
equalize air pressure and disperse odors caused by drain water and wastes outside.
Sometimes, the rocking movement of the motorhome while driving may empty the drain traps
of their water, and allow the odors of the gray water tank to come into the motorhome.
Residue in the drain water lines can also produce odors. To combat gray water holding tank
odors, an approved deodorizing agent should be used. An agent that dissolves grease and fats
and contains a detergent will help keep tank drain lines clean and free-flowing.
Most chemical mixtures for holding tank odor control are poisonous. Follow the product
manufacturer’s directions and warnings when using any holding tank additive.
Both holding tanks are located under the bathroom area. The drain valves are located in the
systems compartment on the driver side of the motorhome. Each tank has a separate drain line
and dump valve, which permits dumping tanks individually or together. Each tank should be
emptied at a dump station designated for this purpose. Most national, state, and private
campgrounds have dumping facilities. Many have hookups at the campsite, while some have
portable dump collectors. Many service stations, particularly along interstate highways, also
have these facilities. Many campground directories list dumping station locations across the
nation.
If possible, dump holding tanks before a trip to reduce the gross weight of the vehicle.
Enough water should be kept in the black water tank to cover the bottom, to prevent
hardening of any residue that may remain.
Do not dump black water tank until it reaches ¾ full. This practice makes sure that enough
water is in the tank to flush all waste into sewer lines. If necessary, fill tank to the ¾ mark with
additional water before draining.
Never put anything into the holding tanks other than normal drain water, waste, and
biodegradable products. Paper wrappers, gum, cigarettes, etc., no matter how small they might
be, should never be placed into either the gray or black tanks.
