We already had World Toilet Day on November 19. Now, starting in 2014, we have World Portable Sanitation Day (WPSD), initiated by the Portable Sanitation Association International (PSAI), on August 15.
The aim of the celebration is to raise awareness about the need to expand access to sustainable sanitation. The PSAI estimates that portable sanitation can save 125 million gallons (470 million litres) of fresh water daily, as well as have a significant impact on productivity and fuel savings at construction sites.
The PSAI has over 550 portable restroom organisations in 34 countries around the world as members. The majority of members are from the USA, where the PSAI is based.
