The described efforts for more efficient water use will put an end to the over-exploitation of aquifers and the entailed destruction of wetlands. Problems of eutrophication and pollution with hazardous substances could be addressed preventively. The turn from end-of-pipe solutions to preventive and production integrated measures would bring about a whole range of possible positive effects on the Environment. As less water would be used, less infrastructure for water supply would be needed. Furthermore there would no longer be a necessity for water transfers from one region to another due to excessive water use in certain areas, mainly for irrigation purposes.

Nevertheless it has to be mentioned, that not every effective solution in one region can be transferred or copied to another region without adapting it to the specific regional situation!
