Water management
Regulating water level without pumps

 
The groundwater level in this area is regulated by connecting ponds with culverts and ditches. In the main ditches are simple devices which can be set to a maximum level at which superfluous water is carried off. So, water is flowing freely away without using pumps, but the level can be regulated.
