I am Tinus Vos. I am the founder of Wetlantec. Wetlantec is acting in water solutions since 1994. We treat all kinds of water and particular waste water/sewage. In Holland we have build already 2400 Constructed Wetlands for treatment of domestic waste water. These system are build mostly in the rural areas where nature is vulnerable. Because of the high efficiency of our constructed wetlands our systems are allowed to discharge the treated waste water in the vulnerable, rural areas.
