Emergency water supply is an important and challenging need. Especially search and rescue detachment/troops, who visit the field soon after the incident for evaluation, lack reliable supply of clean and safe water.

The Swiss based water treatment specialist Trunz Water Systems AG developed a mobile and light weight watermaker that is installed in a shock resistant, non corrosive case – ready to plug in and run.

Lars Willi, COO at Trunz Water Systems: “The idea came up when we went to Haiti for an installation of one of our solar powered, decentralised water treatment units. Aid agency people told us about their difficulties during the first few days after the earthquake and how they struggled to supply their own people with safe water. Trunz is specialised in independent water treatment and desalination system. So we started was thinking of a rather small and compact version based on the same reliable technology we use for our mid-size and larger container units.”

The newly launched product is called “Survivor 300” which emphasizes its goal: immediate clean drinking water for survival in a remote area. Therefore, the unit works independent from any technical or electrical supply. All you need is a fresh water source (lake, river, borehole). Power to operate the unit comes from the integrated solar panels with RV battery pack or if available any other power source (generator). The “Survivor” includes a diaphragm feed pump, prefiltration, an ultrafiltration membrane and an activated carbon filter. The unit delivers 180 litres of clean drinking water per hour – 100 % free of viruses and bacteria.

SURVIVOR 300 facts:

  • 180 liter of fresh water per hour
  • simple to use, ideal for mobile application, light weight 51 kg
  • dimension: 850 x 550 x 350 mm
  • including folded solar panel & batterypack

The target market is not limited to rescue and aid operations. Temporary base camps and expedition camps can take advantage of this highly mobile and easy to operate system.
