Portable Sanitation 101
Portable sanitation is a global industry that impacts billions of people each year. It offers business and employment opportunities while providing essential solutions for users that help keep the world cleaner and healthier. But despite the industry’s prevalence and importance, there are many people — particularly users from the general public — who don’t understand and appreciate how vital portable sanitation is.
At PSAI, one of our goals is to make people more aware of the portable sanitation industry and the positive impact it has on the world. One example of this is our video 5 Things You Never Knew About Portable Sanitation, which you can view below.

Portable restrooms have been used since the 1940s during the height of World War II, with the earliest units being made of wood and metal. They were needed to provide sanitation to meet the needs of rapidly constructed military bases, industrial operations that were booming and similar locations associated with the rapid movement of people into areas where the infrastructure was inadequate.
The post-war building boom and the growing expectations of a traveling public provided the tailwind for industry growth over the next 20 years. By the late 1960s, the portable sanitation industry was well established. Equipment had evolved and people had come to expect better sanitation options wherever they went.
The PSAI was formed in the United States in the early 1970s to serve the common interests of the growing portable sanitation industry and standardize services and communication. By the early 1990s, after many years of invention, innovation and perfection, portable restrooms were more commonplace than ever and the marketplace began introducing new offerings such as flushing units, restroom trailers, VIP units and portable water systems.
Today, portable sanitation is recognized as an integral part of society in many parts of the world. Construction sites, parks, residential home building and special event venues all are expected, and now legislated, to have portable restrooms. The PSAI’s growth has been steady and strong and includes international membership spanning six continents.
