Borewells and Tubewells

India being an agrarian country, our farmers depend mainly on groundwater for irrigation. With increasing population, lesser land holdings and urbanisation, deeper borewells are dug for groundwater abstraction. Borewells & tubewells, are very similar. Both are basically vertical drilled wells, bored into an underground aquifer in the earths surface, to extract water for various purposes. The difference in the two lies in the type of casing used, the depth of this casing and the type of soil where they are drilled. Casing to support the external surfaces of the borehole against collapse may be needed at certain depths, and usually is made up of PVC pipes. Electrical pumps are usually used to pump out the water fro the borewells, though the government is now giving subsidy for solar pumps. This convenience of pumps may increase the depletion of the groundwater at an increased pace.

Our FAQ on borewells, deals in detail with topics ranging from the initial planning, selection of site to final commissioning, maintenance of the structure and problems associated with existing borewells,. Another Frequently asked questions (FAQ) on Groundwater - Understanding the basics, narrows down the existing knowledge gaps amongst the common groundwater users.

Excessive drilling of borewells has led to exploitation of groundwater at higher rates than the rate of water recharge and caused depletion of the groundwater levels. To monitor this many states like Karnataka & Kerala have come up with laws & a statutory authority to regulate and keep tabs on the groundwater utilisation. Some states have implemented groundwater legislation acts which prevent drilling of borewells without the permission of Government Bodies in water scarce regions. However, some states allow only drilling of drinking water borewells without the need for obtaining permission. Therefore, it is advisable to explore the details of it before drilling a borewell.

Central Ground Water Board (CGWB) has come with reports on the groundwater status in the country. Uncontrolled use of bore well technology leads to exploitation of groundwater at higher rates than the rate of water recharge, which may cause drastic depletion of groundwater.

After several failed attempts at retrieving a stuck bore pump from 360 feet in a bore well, our mechanic poured 3kg of washing soap powder into the borewell to ease out the retrieval process as a last option. Finally, we did not succeed in retrieving the pump. During drilling, first water source found at 150 feet and we were stuck after this and were unable to pass from this depth. Our rope, hose and wires were all broken during the retrieval. Now we are lifting water from 150 feet with an air compressor lifting method.

Hi,

We have drilled a bore well 8 months back, which is around 480 ft deep, but we did not install a pump set because of loose soil till 200 ft. To put a casing till 200 ft would have been expensive. This week, we did a video scanning of the bore well and noticed a blockage at 240 ft,  but there is water in the bore well from 55 ft as per the video. We are now confused whether to install pump set til 200 ft or just leave it.

We need suggestion from experts to take decision. Seniors, could you please respond.

An innovative project makes rainwater harvesting easier and more effective in certain areas of Mewat village with increased groundwater salinity.

One of the major causes of deterioration of water quality is the increase in overall salinity. Total hardness and the presence of materials like fluoride, nitrate, iron, arsenic, and toxic metal ions determine salinity levels in groundwater. With the demand for groundwater growing rapidly, its exploitation is also accelerating which causes depletion. Depletion of groundwater changes the flow (both direction and velocity) of the groundwater which may cause the inflow of polluted water into the freshwater aquifer from surrounding areas.

I recently drilled a borewell in my site in Erode, but could not find water source even after going beyond 940 ft, hence stopped the drilling. Before drilling borewell, I got the site verified by water diviner (who brought a machine and found a point to drill. Mr. Natarajan-9842776565). But could not trace water even after crossing 940 ft, though the estimated depth was 650-700 ft. I have wasted my money, nearly 1 lakh!

In the beginning, the borewell water showed a good ph of 8.5, but was greyish color as there was some grey sand getting mixed in it, so we put some pebbles to block the sand from getting in. But now, I am getting a sewage and chemical kind of smell from the water.

I'm really starting to get annoyed, advice is deeply appreciated. My bore well is currently 80 feet, had not used it for 5 years and just got it fixed. We have cleaned the new pump twice, and I have spent around 18K on it. Now the water is kind of whitish with a slight sewage like smell coming from it.

Hello,

I am from Karnataka. I recently digged a borewell which is about 530 feet in depth and the water that was yielded is at 390 feet. I initially installed a 1HP pump 11 stages upto 190 feet depth which was not advisable by anyone. However, I still tried it because I didn't have water and I measured the water to be standing at only 60 feet so I took the risk since I was already having the motor. To my surprise water from the 1HP motor is coming continuously up to 12 hours after which only the pressure is reduced.
