About the PSAI
It is the mission of the Portable Sanitation Association International (PSAI) to expand and improve portable sanitation services and facilities worldwide and to be recognized as the authority within our industry.
The PSAI is an organization which:
• Is recognized Internationally as the credible, authoritative voice of the portable sanitation industry.
• Continues to educate the industry, general public and government entities and provides tools to promote safety and health.

The portable sanitation industry has developed into a 1.5 billion dollar a year business. Worldwide, there are an estimated 1,400,000 portable restrooms in use, serviced by a fleet of 9,400 trucks.
• Construction and various work sites- commercial, industrial, residential, etc.
• Parks and recreation- parks, campgrounds, pools, private homes, etc.
• Government agencies- military facilities, etc.
• Sporting events- stadiums, auto races, golf tournaments, etc.
• Outdoor public gatherings- concerts, festivals, fairs, etc.
• Disaster relief- floods, fires, hurricanes and earthquakes
• Permanent human settlement areas
Benefits of Portable Sanitation
Portable sanitation provides significant labor savings by minimizing lost labor time associated with leaving the site to use the restroom. The average time needed to make an off-site restroom visit is 7 minutes including travel time. According to the University of Missouri-St. Louis study, “Provision of Sanitation Facilities at Construction Sites”, contractors earned an 850% return on their investment in portable facilities.
Portable sanitation provides sanitation facilities where sewer and water are not conveniently available, enhancing the health and environmental factors associated with a project or event.
Health Officials: Builds goodwill and support from health authorities, OSHA inspectors and environmentalists.
Work Force: Outdoor workers who appreciate clean toilets have higher productivity and morale.
Investors: Assures site and building owners that clean conditions are maintained on their property.
Portable sanitation conserves water by using only 6 gallons of clean water to contain the 30 gallons of waste generated by a 10 worker crew during one 40-hour work week. The same personnel, using conventional water flush toilets, could waste up to 2,500 gallons of clean water needed to carry away the 30 gallons of waste they generate.
Route Units: Portable sanitation facilities placed on construction sites or other locations that require regularly scheduled service.
Special Event Units: Portable sanitation facilities placed on a site on a short term basis that require irregular or on-demand service.
Route Units: On a construction site, each weekly serviced toilet unit can accommodate 10 workers (working a single 40-hour shift) ANSI Z4.3-2005.
Special Event Units: Each unit can accommodate approximately 200 uses with 4 hours between uses before service is required. The American with Disability Act requires that 5% of all units ordered be wheelchair accessible, or a minimum of one per each order.

The minimum established standard for route units is weekly service and for special event units when at 1/3 tank capacity.
1. Pumping or evacuating the effluent from the portable toilet receptacle into the truck holding tank.
2. Recharging the portable toilet receptacle.
3. Cleaning the interior of the portable toilet by scrubbing with brushes and towel drying.
4. Providing toilet tissue.
5. Performing minor repairs to the portable toilet as needed.
Effluent is disposed of at licensed and approved disposal sites as needed. Officially approved disposal sites can be found by consulting with local health officials.
The PSAI develops standards directed toward providing clean, sanitary restroom facilities for any gathering of people who do not have adequate permanent facilities close at hand. The PSAI recommends standards to the International Code Council (ICC), OSHA, Council of American Building Officials (CABO), IAPMO and various other country, state, county and local regulatory agencies.

• 1992- The PSAI initiates the Portable Sanitation Worker Certification program that serves as an impartial measure of a portable sanitation worker's competence and understanding of the sanitary and health requirements mandatory to the industry.

The Group is comprised of representatives from the Portable Sanitation Association International, Portable Sanitation Europe, Portable Sanitation Germany (BDE - Bundesverband der Deuschen Entsorgungswirtschaft e.V.) and the Ontario Waste Haulers Association. The mission of the IPSWG is to expand and improve portable sanitation services and facilities, to collaborate with organizations within the portable sanitation industry and to promote the setting and enforcement of standards worldwide.
