PSE
In the United Kingdom, the Trade Association representing operators of Portable Sanitation units is PSE. PSE also has a number of European members and works closely with similar trade organisations worldwide. PSE has a close working relationship with Government departments such as the Health and Safety Executive and Department of the Environment to improve stands of cleanliness and hygiene, and to promote good practice by its members. Unique to the PSE is its members' award scheme. Presently members are able to qualify for a Gold Award after completing a stringent set of assessments set by PSE. In the United States, a similar organization exists called the Portable Sanitation Association International (PSAI).
