We have a Porta-pot and septic pumping business in Montana. We take care of the toilets for the Crow Indian reservation and surrounding areas. Details would include: Transporting toilets, charging them (filling up the "blue Stuff", toilet paper, presher washing, and scrub down), sucking them out, cleaning again, emptying the sludge tank, sucking out residential septic systems and just about anything you can imagine that would have to do with poop and human (sometimes something else's) waste.
