Since 1982 we are consultants in ecological waste water treatment. Our main field of work is the reuse of waste water, treated by natural processes. By special soil filters we achieve category A of the WHO guidelines, which means, irrigation of vegetables to be eaten raw is possible.

The systems can be applied for single houses and for municipal purposes. We co-operate with local engineers, transferring our know how by practical planning work. Our global action include countries as India, Russia, Kirgistan, Philippines and several European countries.

The sewage to be treated can be municipal waste water, grey water, road runoff and industrial waste water. We work out the best solution, combining technical and natural means. If desired, we design integrated reuse options, too.
