Subsurface drainage is important for farming, but the salty water it produces can harm the environment. To solve this problem, a new automated system has been created to manage drainage more efficiently. This system helps reduce salt levels in the water and cuts down on pumping costs. It also ensures that the salty water is disposed of properly, using evaporation basins instead of rivers. This technology is especially useful in areas like the Murrumbidgee Irrigation Area in Australia.
