This is a very cost-effective and strong rainwater harvesting structure wherein multiple semicircular arches are made using locally available stones and cement. The cost incurred for the construction of the 100 feet long dam is merely Rs. 10,000.which is 60% lower than conventional check dam.The design has been studied and validated by IIT, elhi and an architecture group hired by GIAN-W. Further the innovative check dam has been constructed in two sites in
Gujarat and one in Rajasthan. 300 such construction has been approved by Govt of Gujarat.

The innovative device has two extended supporting rod from circular disk that is put on the head, to keep the vessel. So, when any lady wants to give some rest to her head, she can place these two supporting rods on her shoulder, which in turn raises the circular disc just above her head.
