Regulating Waste Disposal from Recreational Vehicles
Montana law regulates the storage and disposal of waste materials from recreational vehicles. The law reads:
"Liquid wastes from sinks, showers, toilets or baths are not allowed to accumulate on the ground surface. Such waste must be discharged into the sewage system serving the trailer court or campground or into an alternate system approved by the department and local health authority." [p>
Kitchen waste water must be held in a watertight and sanitary container. The waste water can be dumped only in a designated waste water sump, a flush toilet, or a trailer holding tank dump station. Pit toilets and sealed vault toilets are not approved dump sites. Kitchen waste water must not be drained onto the ground or into an open container.
Protect your environment. Obey the law.
