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.

The borewell was drilled in 2012 and a pump was installed a year ago in Feb 2016. The water from the borewell is a bit muddy but more of a pale white muddy mix (I have not tested the water and I do intend to test it) over the last 1 year.

I have a bore well which is 850 ft deep. If I switch it on in the morning, it gives me water for 45 minutes, and every now and then I have to keep checking the water flow. This is becoming problematic since morning time it is usually busy getting ready to office and making sure my kids are ready as well. I have observed that when the water flow decreases the Amps will be at 13, is it possible to install auto power cut off switch if Amps fall below 14? Any help on this will be very helpful to me.

Right from day one the borewell water had a high level of iron content, and we have not been able to use it. We are not keen to instal equipments outside the borewell to minimise the iron content. A service provider suggested installing another bigger PVC pipe outside the bore pipe, to reduce iron content to some extent. Is this possible?? He is charging 30% more.

The technician dug the borewell upto a depth of 230 feet, after which he said boring can not be carried out further.About 1 inch of water supply was found at a depth of 150 feet. The casing i.e the pipe which is provided upto the rocks, is of 77 feet in length and 4.5 inches in diameter. We have to install a 1000 litre tank on the roof top which is 15 feet from the ground level and about 15 meters away from the borewell.

I have installed a 15 HP submersible pump (CRI) in my farm in Southern Tamil Nadu. This pump is installed in a 380 feet borewell that has an average yield of 3000 to 3600 litres per hour. The 15 HP pump was installed on basis of a wrong advice provided by the pump dealer as I was looking at installing rain gun and a rain gun required significant pressure. In hindsight a 5 or a 7.5 HP pump should have served the purpose
