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.

Groundwater use has doubled in Pune. Comprehensive mapping of groundwater resources and better management and governance is the need of the hour.

Pune continues to face a water crisis every summer despite having sufficient water, thanks to its geographical location and plentiful natural water assets. While enough of its water needs are taken care of by water supply from the Khadakwasla dam, the use of groundwater to meet the needs of the population continues to increase.

The borewell in our house is 4 years old. From a few months since there were no rains in Bengaluru we had not used the borewell. Recently, when the borewell was turned on, there was a burning smell . When checked with the plumber, he said that the silt/mud from the water has all settled up near the motor which is not allowing to pump the water up. He also suggested to remove the silt, check the motor and fix it back. He said the charges for all this would be around Rs.15,000. Is this a genuine case of silt collecting near the motor? What can be done to fix this? Please suggest.

Hello,

I am looking to improve the groundwater level of my land. We currently have a borewell that supplies water to an RO Plant. I wanted to know if I can use the borewell recharge technique using my RO reject water. My local expert is saying that if we add a layer of charcoal it will act as a natural softner and the system will work. Can you please help me? We are planning to put gutters on our shed to collect rainwater, but since we do not get too much rain we wanted to recycle our RO waste into the bore recharge. Looking forward to hearing from you.

Groundwater, drawn at rapid rates from peri-urban areas of Hyderabad is now turning into a commodity, controlled and distributed by a few, to meet the needs of the urban elite.

Peri urban spaces swept up in the urbanisation tangle

Urban growth and expansion of cities is increasing the demand for land and water, increasing pressure on resources available not only in urban, but also in peri-urban areas. State policies often use peri-urban spaces and resources to meet the needs of urban populations; for instance, they use grazing lands for urban infrastructure, sewerage and water treatment plants or for special economic zones.

I have a farm in West Bengal, Purulia and we have dug a borewell of 720 feet and an 8-inch diameter. The entire bore is through stone so the casing could only be provided till 10 feet and we hit water at around 550 feet and gushing water at 650 so the bore was only possible till 720. We have made an overhead tank at 20 feet above ground, please suggest an optimum pumping solution and depth at which it should be hung.

We have 235 feet borewell at home and we use texmo compression motor to pump. We observed that the water is not pumped up to the water tank from past few days. We could see meagre water in tank even if motor is running for more than an hour. We already had a borewell with 90ft depth and since there was no water, we installed new one last year with a depth of 235ft after checking with experts. We did not face any issues till date and the electrician has checked the motor and confirmed no issues with it.
