Also, those rates my or may not have increased this year.
And yes, USS has you over a barrel for porta potty rentals. I rent them for jobsites locally here in the Dallas area and typically pay around $80 for the month for a single unit that includes a weekly service.
The alternative to USS is Sani-Hut. Sani-hut offers bigger tanks and in our experience much nicer facilities than USS. The ones we had last year from USS looked like they came from a third world construction site. The primary drawback to Sani-Hut that makes them not much of an alternative? Try finding a Sani-Hut pump truck by Friday to service your potties. They are great the first part of the week, but once their trucks are full, they leave, never to be seen again. We got burned 2 years in a row by Sani-Hut and last year by Thursday or so I saw signs on all of the Sani-Hut units requesting service. SH was long gone by then. Oh yeah, you also have to haul them there and back to Reno on your own.
If you pay enough, a USS driver might show some basic human compassion and suck out your full Sani-Hut rental so you can tow it back to Reno, but that is a big maybe as they can get in trouble for even sucking out a non-USS unit.
Playawaste Raiders cordially invites you to suck it.
