Pumping Vault Toilets

Engineer Equipment Operator Tony Aiuppa stands with the pumper truck called the "honeywagon" used to pump vault toilets all around the park.
 

Yellowstone maintains 157 vault toilets throughout the park: you're never further than 10 minutes from a bathroom along the road. Without the "honeywagon" and employees like Tony to pump the toilets, they fill up and temporarily close. To keep up with demand, Tony travels 18,000 miles and pumps 330,000 gallons of human waste each year.

"Some would say it's the most important job in Yellowstone. Well, if it's not number one, it's definitely number two." - Engineer Equipment Operator Tony Aiuppa
