The three small villages San Isidro, Lura and Darien situated in the inner country of Panama now have an independent water treatment supply. In each village a Trunz Water Box  and a solar power center were installed in order to secure drinking water supply for the 100 -250 inhabitant. The water sources are rivers with coffee-brown water which were previously the only available water source. This scenario became history, as Trunz equipment treats the contaminted water to drinking water quality using market-profen ultrafiltration technology.
