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.

How the Doha model of groundwater recharge saved the livelihoods of farmers in Maharashtra.

There was a time when the farmers of Yavatmal district depended completely on rainfed agriculture. That was before the introduction of Doha, a water harvesting structure by NGO Dilasa Sansthan in 2014. Farming changed drastically after that, something which Sitaram Kove, a 40-year-old farmer of Rajini village in the district, will vouch for. Once a distressed farmer like many in Vidarbha and Marathwada, he is now content with the productivity of his six-acre-farm that has doubled since the introduction of Doha.

I am a resident of Andhra Pradesh State. Recently we dug a borewell, from which we started getting water at 146 feet. They continued up to 542 feet and were unable to dig further because the water pressure was too high.

I work in a solar based company in Bangalore. I need specifications on the type of supply either single or three phase, HP of motor and any other useful information.

I have a bore well which is 730 feet deep and since there is lot of slush, I get it cleaned once in two years. I have two 20 feet metal casing pipes installed. This time the lorry person while removing the rod, some how pulled the bottom casing pipe and it crumbled and got stuck at 18 feet. The lorry person said that he could do anything, and he wouldn't even be able to re-bore through the metal. How can I get this casing removed and install a new one? I'm with out water for almost 3 days.

A study from Telangana finds faulty power subsidy policies of the state and the resultant increase in tube wells with electric pumps as reasons for depleting groundwater levels.

The sorry state of urban slums are testimony to poorly implemented policies for the rehabilitation of migrants.

In the last few decades, India has seen an increasing number of people migrating from rural areas to urban cities in search of work and better living. These migrants often get employed in the informal sector as construction workers, vendors, domestic servants, etc. They also live in informal settlements, generally known as slums.

Our area is sandy with water table 3 metres from ground. The height of our building overhead tank is 50 feet from ground level. The existing borewell is 45 feet deep with 4" dia pvc casing. Of late the yield is very low. The rock in our area is 70 feet depth. Can we have a 1 foot dia bore well upto the rock depth with 1"x!" suction jet pump. Can this improve yield? Fill the tank faster? Our doubt is 4" dia borewell is not able to improve the yield. Moreover the slots int casing pipes are choked as the bore well is quite old and perhaps they had used nylon net around the casing pipe.
