    worst company ever. in addition to 4 locations we utilize their services in washington state, we utilize them nationwide for our 30+ onsite locations to empty grey water and provide fresh water on a weekly basis. Nothing but a mess. unreliable service, techs dont empty grey water, fill clean water, dont come at scheduled service dates and overbill us, our location managers are constantly complaining about unreliable service and billing us for service that is not provided. Already looking into local vendors in each market we operate.

    I scheduled a nice restroom trailer for our Girl Scout event for two weeks. Sadly, our lodge was destroyed in an arson fire, and the restroom trailer was supposed to be a nice comfort for the 65 high school girl, volunteers and 45 adult volunteers at the two week camp. Instead, after paying $2650 the trailer never showed up and I never received a phone call. After a long day volunteering at camp, I spent nearly an hour on the phone talking to multiple people. In the end, we never received the trailer and they promised my credit card would not be charged. Three weeks later and they had fine. They had charged my card and still have not refunded it. The worst part is we were really counting on that restroom for use at our outdoor camp. I was promised the supervisor/manager would give me a call back and that never happened either. Very dishonest business, Please be careful dealing with them.

    Ordered a portable toilet trailer that was never delivered, (At least not before we have left) scheduled it delivered a day early assuming that was sufficient and was assured by the rep it would be. Every time I called I was told someone would reach out from “operations” but have never gotten any call. Phone reps can’t even contact the yard people except through email, which is obviously a bad practice. Don’t waste your time or money on an unreliable service. Zero communication. Just hoping I can get my money back now. Will not use USS for personal or business use any longer.

Frequently Asked Questions About United Site Services

What are the guidelines for A.D.A. restrooms?

United Site Services offers portable wheelchair accessible restrooms that are A.D.A. compliant for use on a construction site, commercial area, or special event in some areas. Where available, our A.D.A. units are large enough and contain the proper elements to meet the standards that have been outlined by the 'Americans with Disabilities Act'. Specifically, the statute states that for single user portable toilets clustered at a single location, at least 5% but no less than one toilet unit shall be installed at each cluster whenever typical inaccessible units are provided. Accessible units shall also be identified by the International Symbol of Accessibility. The exception is that if portable toilet units are used exclusively by construction personnel who do not require the use of an A.D.A. unit, you are not required to comply with this statute. (Federal Register/Vol. 56, No. 144/July 26, 1991/Rules and Regulations/4.1.2 Accessible Site and Exterior Facilities: New Construction). For the complete set of A.D.A. guidelines relating to portable restrooms, please contact our office or view our Regulations page.

How much does it cost to rent a Porta Potty?

There are a few factors to consider that can affect the total Porta Potty rental price. What is the length of my event, hours, days, weeks, months? The length of time the unit will actually be in use directly affects how many toilets you might need to order. Weekend event portable toilets and sinks are typically delivered on a weekday leading up to the event and picked up on a weekday following the event. Weekend delivery, service or pickup is available at an additional charge. Upgrades, like flushing toilet restrooms or restrooms with hand wash sinks will be at a higher rental rate than basic Porta Potty rentals. A.D.A. accessible restrooms might be required for your public event, large or small. The standards that have been outlined by the Americans with Disabilities Act state that for single user portable toilets clustered at a single location, at least 5% but no less than one A.D.A. accessible portable toilet shall be provided at each cluster. If you are on a construction job site, you will need to follow A.N.S.I. restroom requirements for the number of toilets needed on site.
