Background on the Portable Restroom Industry
Portable restrooms have been used since the 1940s during the height of World War II, with the earliest units being made out 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 support similar activities associated with the rapid movement of people into areas where the infrastructure was inadequate.
The PSAI Trade Association was formed in the United States in the early 1970s to serve the common interests of the growing industry and to standardize services and communication. By the early 1990s, after many years of invention, innovation and perfection, portable restrooms were more commonplace than ever before and the marketplace begin introducing new offerings such as Restroom Trailers, VIP Units, Portable Water Systems and Solar Powered Units.
In the new millennium, 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 were expected, and now legislated, to have portable restrooms. The PSAI’s growth has been steady and strong, and includes international membership spanning six continents.
