Residents’ resourcefulness replenishes dried up wells
Bore-wells getting dried up in the city has become a common scenario. The two major reasons cited for the scarcity of water in the city (according to records, there is almost 42 percent of water scarcity in the twin cities) are: wastage of water and no proper measure being taken to conserve the same.
Secunderabad: Bore-wells getting dried up in the city has become a common scenario. The two major reasons cited for the scarcity of water in the city (according to records, there is almost 42 percent of water scarcity in the twin cities) are: wastage of water and no proper measure being taken to conserve the same.
Progressive Housing Society Park at Mano Vikas Nagar near Bowenpally in Secunderabad was affected by water crisis till 2015 due to drying up of bore-wells. The colony consists of 26 independent buildings with one park and one main road passing through the middle. The colony has with three bore-wells in the park, each of them measuring 400 feet, 500 feet and 1,000 feet respectively.
The first bore of 400-feet depth dried up long ago followed by seasonal problems in summer with other two bore-wells. The 500- feet-deep well used to get dried during winter/ before the onset of summer and the 1,000-feet bore before April every year. To counter this, the people in the colony undertook a water harvesting project. Two big size rain water harvesting pits in the park were constructed with necessary filling materials like boulders, gravel and sand for filtering effect. The second pit included 400-feet deep bore-well used for recharge.
The park is located by the side of the main road. One small speed breaker was constructed horizontally across the road. The speed breaker works as a check dam for the rainwater run off that flows as road floods during rains.
The partially arrested water from the road enters the park through the big hole made in the compound wall of the park. That is again diverted to pass through two rainwater harvesting pits serially. The excess of water after getting filtered in the two pits is directed to enter the unused bore-well provided in the second pit.
There are holes made in the lower section of the pipe of the bore (boulder area) of the pit, so that the filtered water can enter the pipe directly and thus, reach the groundwater tables unhindered.
It was reported that, by using this method, the bore-well started giving water within just 15 days with the onset of monsoon with just 2-3 rainfalls only. The 500-feet bore-well that went dry in winter months started giving water, indicating that the water table has risen to that levels.
This method is conventional and highly cost-effective compared to the money we invest in buying waters from tankers and shops which are actually not safe for drinking.
