How to service a porta potty yourself if you own one: the steps and the rules
I drive a vacuum truck for a rental company and see a lot of folks who've bought a used standard portable toilet for a hunting camp or a remote property. They ask me what it takes to service it themselves. I can walk you through the steps: you need a wet/dry vac rated for waste, a dedicated transfer tank, a supply of formaldehyde-free deodorizer, and paper. You pump the holding tank, clean the interior with a disinfectant, and recharge the deodorizer.
But here's the catch: the waste disposal part is regulated. You can't just dump it in a ditch or your home septic. In the U.S., that waste must go to a wastewater treatment plant or an approved facility, hauled by a permitted septage hauler. Doing it yourself usually breaks the law.
For those who own a unit, what do you do with the waste? Have you found a legal drop-off point, or do you just call a service truck when it's full?
