On the 8th of February, 2007, a solar/wind powered water purification system (Trunz) was installed at the Lynedoch EcoVillage. This unit can process water from lakes, rivers, boreholes, ocean seas and even semi-treated effluent from sewage treatment facilities, transforming polluted water into potable quality water. Using activated carbon filters, microfiltration, reverse osmosis for water desalination/demineralisation, this system can purify 20,000 litres of water per day.
The Trunz system, manufactured in Switzerland, is currently operational in Mauritania, Pakistan, Switzerland and is now being tested in South Africa at the Sustainability Institute. It has been designed for application in developing countires, disaster areas, and remote regions without access to electricity and clean water. For more information please visit the Trunz website.
