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.

Hi,

Iam planning to drill a borewell and also recharge it with harvested rainwater, what are the information I should know beforehand.

Also, what would be the estimated cost of drilling a bore per ft and the casing pipe per ft?

Hello,

In August 2012, we had a borewell in our house which is under construction. Water struck at 45 feets and we have gone till 170 feets and stopped. The bore width is 4.5 inches. Upto January 2013 water was coming for 5 to 6 hours continously but now the water outflow is not more than 5 mins in 12hrs. Yesterday, we installed a submersile pump V3 1 hp 10 stage model, but still no help. Please advice what could be the issue and how to fix it.

Hi,

We drilled borewell in 2008, 4"inch wide and 290 feet deep. The water level is at 100 feet. The submersible motor (CRI) is at 130 feet. It is working superb since the last 2 years.Then mud destroyed the pump suction motor and it was able to lifts water properly.

We got it repaired from the local market and it worked fine for sometime, but now mud destroyed pump suction again.

Hello,

Borewell depth 510 feet with 6.5 inch bore and water yeild is 1.5 inches in Salem district, Tamil Nadu. Should I install a submersible pump or compressor and what capaicty for irrigation purpose.

How can I identify groundwater points/location for drilling borewell; as well the approximate depth to drill at Kurdawadi, Solapur. Water diviners use sticks, copper ring, coconut etc., to identify the source. Which of these are reliable and believable. Is there a scientific way like hydro-geology or satellite mapping that is available and more reliable.

Thank you

Total depth of borewell 180 feet, water trace found at 120 feet and water flow from 150 feet, but the drillers stopped the casing pipe at 100 feet in Vadavalli, Coimbatore. 

Though the water flow is satisfactory through the 1 inch pipe, I want to know if it is okay to stop the casing pipe at 100 feet and should the length of casing be increased.

Dear All,

We drilled a borewell about a year and half back upto a depth of 150 ft and had to stop as we encountered boulders in Bangalore. Now the bore is completely dry.

We were informed by the person who checks the water source that there is water available beyond the boulders.

Would like to know if the blouders can be crushed and dug further to find the water source or I should not proceed further.

Thanks,

Karthik

Analysing the changes in land uses between 1989 and 2009, this paper assesses the impact on water balance in Mula and Mutha Rivers catchment upstream of the city of Pune

Land use changes  hydrologic system and have potentially large impacts on water resources. An assessment in an area with seasonally limited water availability and which is subject to rapid socio- economic development and population growth will provide an exemplary view on the local impacts of major recent developments in India. In this backdrop this paper analyzes past land use changes between 1989 and 2009 and their impacts on the water balance in the Mula and Mutha Rivers catchment upstream of Pune. The aim of the paper is:

  • assess the land use changes between 1989/1990 and 2009/2010
  • analyze the impacts of these changes on the long-term water balance components in the Mula and Mutha Rivers catchment upstream of the city of Pune.
