Here in the US for instance, a law has been passed to insure their continued water rights interests. It states that it is now unlawful for farmers to dig catchponds to capture and hold rainwater.This is to ensure they have to buy water from the authorities in charge of water management.This is gearing up to be the next commodity to be fully regulated as more and more countries experience drought like conditions. A bill was passed a few years ago ptting the army corp of engineers in charge of all running water.If it runs through your property, you can't dam or control the stream of water. Now they have taken it a step further, to include catchment of runoff rainwater. rockhound
