I'm Mariah Jackson, and I started Genesee Portable Toilets back in 2008. Back then, we were just a single truck and a handful of units, mostly for the small construction crews that were still building around here. We learned the hard way about Michigan winters—I remember one January morning at a site off Ballenger Hwy where the pump hose froze solid before we could even start servicing. That's when we figured out our cold-weather routine: heated trucks, non-freezing blue solution, and we never schedule a service call for first thing in the morning when everything's still locked in ice. We do that because a unit that's frozen shut is useless to a crew trying to get a foundation poured.
Then the water crisis hit Flint, and everything changed. We saw people lining up for bottled water, and suddenly, reliable sanitation wasn't just a convenience for a job site—it became a basic need for community events, health clinics, and relief stations. We got calls from folks organizing in the College & Cultural Center and over in Carriage Town, and they needed units that worked, period. No breakdowns, no mess. That experience is why we're so stubborn about our maintenance. Every unit gets a full scrub-down and sanitization at our yard before it rolls out again. We don't cut corners because we've seen what happens when infrastructure fails people.
Our crew's got the certifications to back up that promise—PSAI for industry standards, OSHA 10 for site safety, and the state waste hauler permit that lets us handle everything properly. You won't find a more experienced team in Genesee County. We know this area's rhythm, from the student move-in rush around Kettering University and University Park in the fall to the summer festival setups in Max Brandon Park S.E..
We've built our service around being dependable, especially in a city where new construction's been rare. Whether it's a long-term rental for a renovation project in Columbia Heights or a single unit for a weekend backyard event in the College Cultural neighborhood, our process is the same: we deliver a clean, stocked unit on time, and we show up for servicing like clockwork. You can set your watch by our truck pulling up on Dartmouth Street West. We keep a tight fleet of well-maintained standard units, deluxe models with hand sanitizers, and ADA-compliant units, so we've got the right fit. After 16 years, our word is our bond. If we say a unit will be there Tuesday morning, it's there. That's the only way we know how to run this business.
