Recreational Vehicle Waste Disposal Stations at Highway Rest Areas

Description: A study of recreational vehicle waste disposal at highway rest areas was conducted from 1980-1982. RV wastewater is significantly stronger than restroom wastewater in BOD, COD, and suspended solids. It also contains preservative compounds, most of which contain formaldehyde or a formaldehyde derivative. With adequate dilution, these wastes should not interfere with waste treatment by mixed cultures of aerobic or anaerobic bacteria or algae. There is potential that waste treatment facilities will be affected by improper use of the disposal stations, such as for disposal of hazardous wastes. In addition, improper use may lead to temporary unsanitary conditions around the station.

Equations to estimate disposal station use and loading factors, and design equations for treatment of RV wastes are presented. 

The public perceives the stations to be beneficial and cost-effective provided they are paid for by RV owners. RV owners are willing to pay an annual fee which will cover the costs of construction, operation and maintenance of the stations.
