  • Only exit your vehicle if you are dumping the recreational vehicle (RV) tank. You must monitor the tank dump the entire time it is emptying.
  • Non-drinkable flushing water is provided as weather permits. During cold weather the water is turned off.
  • Please ensure only toilet and sink/shower waste is dumped into the wastewater system. A minimal amount of toilet waste deodorizer is allowed.
  • Never dump items harmful to the wastewater treatment process such as toxic chemicals, fats/oils and greases, flushable wipes or other debris not considered human waste.
