August 15, 2014 is World Portable Sanitation Day

World Portable Sanitation Day

Here in the United States, it’s easy to forget how important adequate sanitation is to a community. The truth is, according to the World Health Organization, an estimated 2.6 billion people globally lack access to proper sanitation. If you do the math, that is around a third of the world’s population that lacks even basic sanitation services. If those numbers are shocking to you, there are things that you can do to help.

We here at On Site are participating in Word Portable Sanitation Day, which is being held on August 15, 2014. The Portable Sanitation Association International (PSAI) is organizing this event in large part, to help spread awareness of the importance, and great need, for increased portable sanitation availability throughout the world.

The PSAI will be organizing several events around the country to promote the cause of global sanitization, and more information will be announced throughout the summer. They have designed a logo for this event to symbolize “the vital relationships between people, the environment and portable sanitation through the use of a human face, portable restroom and the colors blue, green and white.”

On Site will also be participating in events highlighting World Portable Sanitation Day, and we will keep you updated on what those events are. If you are looking for ways to get involved in this event you can contact the PSAI on their website at or you can download the World Portable Sanitation Day Toolkit here at .
