CleanVertex Porta Potty SolutionsCleanVertex Porta Potty SolutionsOn most Salt Lake City construction sites, each portable toilet gets serviced once a week — that's the baseline, and it holds up as long as you've got roughly 10 workers or fewer per unit on a standard 40-hour week. Push past that headcount, run Saturdays, or add a second shift, and weekly stops being enough. Twice-weekly service is common on bigger builds. Crew size, hours worked, weather, and how easy the unit is to reach all move the number. Everything below is how that plays out on real sites from Rose Park to the Avenues.
One service visit per unit, per week, is the standard cadence on a typical Salt Lake City construction site. I learned the hard way what happens when you guess low on that. Years back I set a single unit on a small infill build off 800 West in Poplar Grove, took the super's word that it'd be "five or six guys," and by Thursday there were fourteen framers, a concrete crew, and an inspector all sharing it. That unit didn't need a service day. It needed an apology. So — weekly. The industry rule of thumb, and it's a decent one, is one unit per 10 workers on a 40-hour week with weekly servicing. OSHA's construction sanitation rule requires job-site toilet facilities and scales the count with crew size, so the 10-per-unit habit gives you some cushion rather than sitting right on the line. Do you have to think about it every week? No. That's the whole point of a published service day. You should know which day of the week the truck comes, and it should be the same day, every week, without you calling to ask.
Bump past roughly 10 workers per unit — or add hours beyond a normal week — and you either add units or add a service day. Simple math, mostly. Twenty guys and one unit on weekly service is a losing setup by Wednesday, and everyone on site knows it before you do. Here's the mental model I use: headcount and hours together make the load, and the load fills the tank. A ten-man crew working 40 hours is a very different animal than a ten-man crew working 55 hours plus Saturdays during a tight schedule push. Same headcount. Way more use. On the bigger commercial jobs downtown and near the U — where you've got trades stacked and a hundred-plus people badged in — supers usually land on multiple units with <strong>twice-weekly service</strong>, sometimes more during peak trade stacking. Also worth saying: your unit count and your service count are two separate dials. Adding a second unit spreads the load. Adding a service day resets it. Most sites need a little of both as the job ramps.
Winter doesn't reduce how often a unit needs service — it makes access and handling the harder part. January along the Wasatch Front is its own thing. You get inversion sitting in the valley for two weeks, then a foot of snow, then a melt-freeze cycle that turns your laydown yard into a skating rink. A few things I'd tell any super planning a winter build here. First, don't let the plow crew bury the unit. I've shown up to a job off Redwood Road where the unit was technically accessible and technically behind a four-foot berm of dirty snow. Second, keep the path to it clear enough for a hose and a hand truck — service techs work fast when they can walk straight up to the door. Third, winter units get used differently. Guys spend less time outside, more time bunched up around break, and the unit takes a beating in short bursts. Cold weather also means antifreeze in the tank and a bit more care on the pump-out. It's normal. It's part of the job here. What matters is that the service day doesn't get skipped because the weather looked ugly.
A unit is only as serviceable as the truck's access to it, so placement decides your real service reliability. This is the part that gets skipped on quotes and then causes half a day of lost time later. Think about the Avenues — narrow streets, tight parking, older homes with detached garages and alley access off the numbered avenues. A service truck needs somewhere to sit and a reasonable reach to the unit. Same story on those Sugar House infill lots near 2100 South where the setback is nothing and the neighbor's fence is right there. Rose Park and Fairpark are usually friendlier, wider streets, more room to swing. Glendale and Liberty Wells are a mixed bag block to block. My rule: put the unit where the truck can get within reach without blocking your only equipment lane, and where it isn't in the way of a delivery or an inspection. Not at the bottom of the excavation. Not behind the material stack you're about to build. We ask about access before delivery and confirm the spot in writing, because <strong>a unit in the wrong place gets moved twice and serviced late</strong> — and that's the thing supers actually complain about.
A service visit means the waste tank is pumped, the unit is cleaned inside, fresh deodorizer and water go in, and consumables get restocked. Not a quick peek and a spray. The tech pumps the holding tank out, washes down the bowl, seat, urinal, and interior surfaces, refills the tank with fresh water and deodorizer, and restocks toilet paper and hand sanitizer if that's part of your setup. Doors and vents get a look. Damage gets noted. If the unit's been knocked around by a skid steer — happens more than anyone admits — that's when you find out. You should get some kind of notification that the service happened. Honestly, that one detail separates a supplier you have to babysit from one you don't. <strong>You shouldn't have to walk out to the unit to find out whether the truck came.</strong> If your current outfit's service day is more of a suggestion, that's the problem worth fixing, not the price.
Service frequency, not the unit itself, is what moves the monthly number most. A standard unit on weekly service sits at one price; the same unit on twice-weekly service costs meaningfully more, because you're buying a second truck visit every week. Delivery distance matters too — a downtown site, a Rose Park lot, and something up a canyon road aren't the same drive. Our minimum charge is <strong>$150</strong>, and beyond that, monthly rates in the Salt Lake market vary with unit type, service cadence, rental length, and access. I'm not going to pretend I can give you an exact figure from a paragraph on a web page. Ranges are honest; "instant exact price" isn't. What we do instead is walk the site, look at the access, count your projected headcount and hours, and put the quantity, delivery window, and service day in writing so nothing gets guessed at.

The clearest sign you're under-serviced is a unit that smells before service day arrives. Here's what I watch for. One, odor showing up on day four or five instead of day six or seven — that's a load problem, not a cleaning problem. Two, a line at break. If guys are waiting, you're short a unit, and you're paying for that wait in labor whether you see it on a timecard or not. Three, paper running out mid-week. Four, the unit tipping toward full when the tech arrives — your tech will tell you, and you should listen. The fix is usually cheap relative to the alternative. Adding a unit or a mid-week service is a small line item. Losing crew time, or catching grief from an inspector, or having the same conversation with your foreman every Monday — that costs more. When a job ramps from eight guys to thirty, call and change the plan. That's a two-minute phone call, and it beats hoping the original setup still fits.
The common industry rule of thumb is one unit per 10 workers on a standard 40-hour week with weekly service. OSHA's construction sanitation rule requires job-site toilet facilities and scales required counts with crew size, so planning at one per 10 gives you cushion rather than sitting at the minimum. Longer hours or weekend work reduce how many people one unit comfortably supports.
Winter usually doesn't increase the service frequency itself, but it does change handling and access. Cold weather means antifreeze in the holding tank and more care during pump-out, and snow removal on site can block the unit if nobody plans for it. Keeping a clear walking path and truck access is the single biggest thing a super can do to keep winter service days on schedule.
The technician pumps the waste tank, cleans the interior surfaces including bowl, seat, and urinal, refills fresh water and deodorizer, and restocks toilet paper and hand sanitizer where those are part of the setup. Doors, vents, and any damage get checked. On sites where units take equipment hits, that inspection is often how the damage gets reported first.
Cost depends on unit type, service frequency, rental length, and site access, and our minimum charge is $150. Twice-weekly service costs more than weekly because it's a second truck visit each week. Exact pricing gets confirmed after a free look at the site, since access and placement affect the number as much as the unit does.
Usually yes, with placement planned in advance. Narrow streets in The Avenues and tight infill lots around Sugar House mean the unit needs to sit where the truck can park and reach it without blocking the equipment lane. Confirming the exact spot and access route before delivery prevents the unit from being moved twice and serviced late.
