ABSTRACT:
The disclosure herein describes a control device for use with an underground drainage network of main collectors and adjacently disposed water-collecting pipes. A head control stand is used defining a water-collecting chamber with a float member therein. The latter is operatively connected to a valve disposed in an associated main collector and is opened as a result of the float member being influenced by the measurement of the water table depth between two adjacently disposed water-collecting pipes of the network. The valve remains opened as long as the level of underground water exceeds a value corresponding to optimal plant growth.
