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.

  • Offline iron remover installed for borewell water. After one year, black water comes often. When we cleaned the tank, we found sandy coal like black substance. Could it be due to the wear out of the iron remover or contaminated water.

Borewell is drilled till 280ft. Got water at 90ft, however, after 110 ft got sand up to 160ft after that there is rock. Casing is up to 119ft. Now the motor pump is at 150ft. Getting to much sandy water. After few hours water is not coming, but the motor continues to run. This is happening again and again. What is the solution?

Dear team,

We are living in a hilly area in Hyderabad. We have already constructed a house and its more difficult to bore now. We are looking for mini borewell now with less noise and that can be drilled upto the depth of 200-250.

Thanks Dinesh

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.
