HOWTO: Waste Water Dumping
Wastewater storage and dumping
Your house is permanently connected to your septic system or a municipal sewer; you don't have to worry about the
wastewater you generate because gravity takes it away. Your Roadtrek doesn't have that connection, and has to hold any
wastewater until you have the opportunity to dump it at an approved dump station.
Most municipalities have severe penalties for improper disposal of human waste, especially into a watershed - fines
can be several thousand dollars, and it's often a felony. Even if it's "just gray water", it will still flunk a coliform bacteria
test because of the common discharge hose, which is difficult to explain to a judge. Never dispose of wastewater unless
you're sure you are at an approved dump station.
Tanks
Your vehicle is equipped with a gray holding tank and a black holding tank. The gray tank holds the sink and shower water.
The black tank holds the toilet waste. As a result the black tank is a lot nastier than the gray tank.
Waste Water Discharge Pump
Your Roadtrek is equipped with a waste water disposal pump to make dumping your tanks easier and cleaner. The macerator
in this pump grinds up any solids in the system and pumps the resulting wastewater out to the dump station.
Do not throw any paper towels, personal wipes, rags, baby wipes, tampons, hairballs, etc. into the toilet. The
macerator is not capable of handling these types of solids and will jam or be damaged. Use toilet paper intended for RVs
or septic systems.
If in doubt, take a tissue, and leave it in a glass of water. Stir with a spoon a couple of times. If it falls apart into a
gooey slurry after a few minutes it`s safe for your tank. If it stays together, swells up, or clumps into a solid mass, it`s
not safe and should be disposed of in the trash and not down the toilet.
