Small River Bridges to Serve as Cost-Effective Water Storage Structures

Small rivers having waterway up to 30 m gets virtually dried up in few hours after the rains have stopped. Normally, in such rivers, maximum flood depth seldom exceeds 4 m. These rivers do not contribute much to ground water recharging. Generally, for all such small rives, bridge structures are constructed. These bridge structures are converted into storage structure by constructing an RCC meticulously designed elliptical arch touching upstream piers to create storage up to 2.4 m. Normally, there are twenty rainy days. Each instance of rainfall can bring 8000 cubic meter of water, and this water would be used to fill the farm ponds using solar pumps. The entire water can then be used for irrigation. Using these structures, ground water table has been increased by 25 m in one case. The cost of such storage structures is less than Rs. 60,000–750,000 per running meter which is affordable. Objective of this paper is to highlight such low-cost elliptical structures which are used to make water storages that are used for sustainable irrigation.
