In 2004, on initiative of Casper van Ommen and Jacques van Paassen, a drinking water production was constructed and taken into operation at the location Tan-Kim using by Vitens donated used drinking water materials and equipment. In 2006 the drinking water purification system of Abott-Zwolle, the Netherlands, was stripped down and rebuild in Truong Binh (close to Ho Chi Minh City). The local drinking water company HoWaCo (Water Supply Holland) of former colleague Truong Ngo is owner and runs the drinking water supply. The Foundation Water is our World is arisen out of this initiative. Mid-2013 about 20,000 people now have a reliable drinking water supply. Expansion plans are in development.
