Portable Sanitation Association International (PSAI) held the second annual World Portable Sanitation Day (WPSD) in August. The inaugural day in 2014 kicked off a campaign to raise awareness and promote change by engaging people in expanding access to sustainable sanitation. Organisers said that portable sanitation saves an estimated 473 million litres of fresh water each day. Karleen Kos, Executive Director, PSAI, points out that the portable sanitation industry can play an integral role in addressing some of the biggest challenges currently facing the world’s citizens. “Parts of the globe are facing severe droughts,” she said. “Solutions that use less water are an essential part of coping with water shortages.” Kos notes that in some parts of the world, portable toilets may be the only practical answer.
