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.

Dear Sir,

I have a submersible pump installed at my hometown - Gonda in UP. The water comes out good if we use the running water while the pump is running. However, the stored water turns to brownish red after 10 mins. It also leaves a lot of sleuth ( brownish red ) on all the buckets, tap and shower head. We are using RO to filter the drinking water. How can I treat this water to rectify the problem. Can I add a filter before the water hits my storage tank or to the pipeline from the tank to my pipelines? Thanks Amol.

1) If Agriculture borewell fails, can we restore the water in rainy season to recharge the same borewell. Can a failed borewell be converted into water source borewell to utilise the water in needy days to feed the plants.

2). For three acres of land of plants with agro-forestry method (nearly 4000 plants), what is the agri-pond size and its maintenance process for long term agri activities.

Thanking you,
Regards

Dear Sir,

This is S.Subramanian. I have two borewells in my home (70 feet and 200 feet). I recently dug the 200 feet borewell whereas the 70 feet was dug ~ 20 years ago. Can I use a single compressor pump to alternatively draw water from two borewells. I use 0.5HP jet pump as of now in the 70 feet borewell. The water level is dropping and hence I switch on every 5 hrs for 10 mins.

Thank you.
Yours Sincerely,
S.Subramanian

Borewell was digged two weeks back, it is was giving enough water. Due to some reason motor got burnt, we took it out, repaird it & ran again. After running for two hours it stopped. We tried to start again but it never started, then we tried to take out the motor pump from the borewell to check it. Now it is stuck at 230 feet with 7 inch dia. What can be done? Please suggest.

Hi

The borewell water in our home shows a TDS of 1150. Could you recommend a solution for lowering it to less than 100. Its causing unsightly stains on the floor, walls, sinks, taps etc. Your advice would be greatly appreciated. This is for my home of 8 persons.

Toxic industrial waste has polluted groundwater in Ratlam. Residents wait for action from authorities.

A resident of Bajankheda village in Ratlam district of Madhya Pradesh, Sitabai Tindor shows her pot full of water to us. A strange red, the water looks unusual. “We have been using this red water for domestic use for the last two decades. Industries in Ratlam has spoilt our land and water. The government has not provided us with any alternatives. For industrial misdeeds, why should we suffer?” asks a visibly distraught Sitabai.

A study points out that pit latrines with onsite sanitation systems are a source of groundwater contamination.

Groundwater is a major source of water for a large number of Indians with 66 percent rural households and 27 percent urban households directly depending on it for drinking purposes, as per Census 2011. There is a greater daily dependence on groundwater for non-potable uses.
