The Waterkiosk is an outdoor solar water desalination system developed by Boreal Light GmbH for off-grid outdoor communities lacking access to clean water. The Waterkiosks are based on modified reverse osmosis (RO) systems and are able to produce 4 types of water quality: drinking water, irrigation water, fish farm water and sanitation water. The kiosks have been implemented in Kenya, Yemen, Somalia, Tanzania, and Madagascar and can produce between 5,000 to 20,000 L/day, serving up to 5,000 people.
