How many porta potties do I need for my event or job site?
The math depends on how many people show up and how long they stay. For construction, OSHA 1926.51(c)(1) requires one toilet facility for 20 workers or fewer; from 20 up, the ratio is one toilet seat and one urinal per 40 workers, then one per 50 workers once you hit 200. An event in Tempe Junction with 100 guests over four hours needs fewer units than a three-week build site with rotating crews. How Many Porta Potties Do I Need in Tempe Junction, AZ walks through the calculator. Call us with your headcount and duration and we'll quote you what makes sense.
What's the difference between a standard unit and a deluxe flushable?
A Standard Porta Potty Rental in Tempe Junction, AZ holds 60 to 70 gallons and sits about 44 by 48 inches on the ground, standing roughly 92 inches tall. It's a gravity tank. A Deluxe Flushable Porta Potty has a working flush and running water, better lighting, a sink and a hand towel dispenser. Both get serviced weekly as baseline under ANSI/PSAI Z4.3. Deluxe units cost more and take up slightly more space, but they're popular for offices, events and anywhere image matters. Standard units are the workhorse on construction sites and farms.
Do I need an ADA accessible unit?
Yes if anyone using the site has mobility challenges. ADA Standards section 213.2 requires that where single-user portable toilet units are clustered, at least 5 percent, and never fewer than one unit, must be accessible. An ADA Accessible Porta Potty has a 36 inch minimum clear width route per ADA Standards section 403.5.1, a 32 inch clear door opening, a 60 inch turning circle for wheelchair users, and grab bars positioned for safe transfer. If your crew or guest list includes anyone who'll need it, include at least one. Federal law covers it; it's the right call.
How do septic tanks and grease traps work?
A residential septic tank is typically pumped every 3 to 5 years, driven by tank size and household size. A grease interceptor gets pumped when fats, oils, grease and solids reach 25 percent of the liquid depth, which on a busy kitchen might be months. Septic Tank Cleaning removes solids and sludge before they clog your drain field. Grease Trap Pumping pulls out the buildup before it hardens and blocks your line. Both are preventive. Skip them and you pay for a backed-up system, repair bills and downtime. Call Tempe Junction Porta Pros when you see slow drains or smell problems.
