A porta potty is a self-contained toilet with a 60 to 70 gallon holding tank, a non-toxic deodorizing chemical, and no plumbing hookup at all. Waste and chemical mix in the tank below the seat. Hawthorne Porta Pros services and pumps that tank on a set schedule, so the unit works the same on day one and week four.
There's no water line, no sewer line, nothing running under the ground to the unit. The tank sits right under the seat, and a blue or green chemical solution in the bottom breaks down waste and knocks back odor between services. A construction worker running to a porta potty on a job site just opens the door, uses it, and walks away. No flush handle, no tank refill. Standard porta potty rental covers most job sites and yards in Hawthorne without any extra plumbing work. ANSI/PSAI Z4.3, the industry service standard, sets one visit per week as the baseline for up to 10 users over a 40 hour week, which is why a busy site or event needs more frequent pumping or more units, not a bigger tank. If you're not sure how many you need for a crew size, the porta potty placement guide and the how many porta potties do I need page both walk through the math. Standard units run in the 100 to 350 dollar range for a single day rental, and pricing scales differently for a week or a month, which is broken down on the porta potty rental cost page.
A flushable, or deluxe, unit has a small onboard freshwater tank and a foot pump or hand pump that pushes a rinse of water into the bowl after use, flushing waste down into the same style of holding tank below. It feels closer to a real bathroom, with a sink, a mirror, and sometimes a paper towel dispenser. These units cost more than a standard unit, roughly 85 to 1200 dollars a day depending on the package, and they're the right call for weddings and higher-end events. The deluxe flushable porta potty page has the full lineup. For an ADA-compliant version with a ramp and wider stance, the ADA accessible porta potty unit meets ADA Standards 213.2, which requires at least 5 percent of clustered single-user units to be accessible, and never fewer than one. Those units also meet ADA Standards 404.2.3 for a 32 inch clear door opening and ADA Standards 304.3.1 for a 60 inch turning circle inside. Weddings in Hawthorne often pair a deluxe or ADA unit with a wedding restroom rental package, and larger events step up to a restroom trailer rental with multiple stalls.
A portable sink, sometimes called a handwashing station, holds its own fresh water in a tank, usually gravity fed or foot pumped, and drains into a separate gray water tank underneath. Nothing connects to a building or a hose bib. 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device at washing facilities, and hand sanitizer alone doesn't satisfy that. On a construction site using paints, coatings, herbicides, or insecticides, OSHA 1926.51(f)(1) specifically requires washing facilities for that contaminant exposure, separate from general toilet counts. The handwashing station rental and portable sink rental pages cover unit sizes, and the handwashing requirements page breaks down when a jobsite in Hawthorne needs one versus a hand sanitizer station, covered on the hand sanitizer station rental page. OSHA 1926.51(c) sets the toilet ratio itself: one facility for 20 workers or fewer, then one toilet seat and one urinal per 40 workers as crews grow past that.
Camping units work exactly like a standard porta potty, just smaller and easier to move between sites, detailed on the camping porta potty page. A residential septic tank is a different animal entirely: it's a buried tank that holds and partially breaks down wastewater from an actual house, typically pumped every 3 to 5 years depending on tank size and household size. Septic tank cleaning chemicals sold at hardware stores claim to break down solids between pumpings, but they don't replace a pump-out, and overusing them can actually damage the tank's natural bacteria balance. A grease interceptor works on a similar principle but needs pumping sooner, once fats, oils, grease and solids hit 25 percent of the liquid depth. Hawthorne Porta Pros handles both through septic pumping service and grease trap pumping, with septic pump-outs running 150 to 300 dollars for a day service. If your tank is showing signs of trouble, the septic tank warning signs page lists what to watch for, and how often to pump a septic tank goes deeper on the 3 to 5 year interval.
They shouldn't, if serviced on schedule. The deodorizing chemical in the tank controls most odor between pump-outs, and regular service keeps it that way. See do porta potties smell for what causes a smell problem and how fast Hawthorne Porta Pros fixes it.
ANSI/PSAI Z4.3 sets a weekly baseline for up to 10 users over a 40 hour week. Busy job sites or multi-day events need more frequent pumping. Full detail is on how often are porta potties cleaned.
A non-toxic deodorizing solution, usually blue or green, sits in the holding tank and breaks down waste while suppressing odor. It's not the same as household septic tank cleaning chemicals, which target a different kind of tank entirely.
Yes. Weekend rates run higher than a single weekday because of setup and pickup logistics, generally landing between 125 and 400 dollars for a standard unit depending on the event. Event restroom rental covers weekend and multi-day event pricing.
