How do you size sanitary dump stations for RVs with a disposal system?

The correct answer highlights the recommended sizing for sanitary dump stations, which is based on the typical wastewater generation from RVs that do not have access to a sewer system. The standard guidance suggests that you allocate approximately 20 gallons per day for each unsewered RV site. This estimate reflects the average usage patterns of RV occupants, accounting for factors such as toilet flushing, shower use, and other wastewater contributions over a 24-hour period.

Using this standard helps ensure that the sanitary dump station can adequately accommodate the waste generated without overloading the system. Proper sizing is crucial for maintaining hygienic conditions and preventing public health issues related to wastewater management.

Other options, while they may represent different guidelines or assumptions, do not align with the accepted average for unsewered RV sites. By using 20 gallons per day, planners and installers can design facilities that meet actual usage needs effectively without risking overflow or inadequate waste disposal.
