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. 

  • We have around 400 feet borewell, but for some reason we did not use it for long. Recently, we tried to use the borewell but could not extract any water, so we tried to pull the motor to see if it was functioning properly. However, while pulling the motor up it fell into the borehole but the remaini...

  • Hello, We have three borewells on our premises which were dug when our building was constructed. They are about 700 to 850 feet in depth. One well which used to yield good amount of water has now come down to a trickle. Is it worth carrying out a hydro fracture procedure on this well? Reji Thomas

Hello,

We are in the process of flushing our community borewells that have dropped in yield. The vendor tells us that there is a low cost compressor flushing with 2-3 kg pressure and a high cost flushing where the rig goes in and flushes the borewell with 20 kg plus pressure. He recommends the high pressure flushing for better cleaning. I want to understand the process better and then decide . Any advice please ?

INREM Foundation and The Fluoride Network have worked in Chikkaballapur extensively, to battle the problem of fluoride contamination in groundwater.

Chikkaballapur is a district in the state of Karnataka, just north of the capital Bengaluru. A peri-urban area that was once an agricultural centre for this region, today Chikkaballapur is facing a unique problem. 

Decreasing rainfall has meant increasing periods of drought for this area, which in turn has caused residents to dig deeper and deeper in search of water. In this pursuit for groundwater, they have found water… but it is contaminated with fluoride.

3 phase 20hp motor running at 1000ft and the voltage shows as 360-380v at 11am and the motor runs for 24 hrs everyday. The water output has reduced significantly and the mcb is 63A 415V. Not able to figure out the problem why the water bill is coming up to 1,65000 to 1,80000. Varies monthly, but in none of the months it has fluctuated more than 10,000 but in the past month it has fluctuated of over 30,000. Please help.

What will be the recharge rate of a borewell of 150 mm and 300 mm diameter, respectively in the district of Patiala, Punjab for the purpose of rainwater harvesting. The borewell ends about 15 meter before the first aquifer and hence sends the water into a layer of sand. The borewell will have perforations in the last 10 meters depth.
