Satara District: Water availability, Borewell Problems:

Our case is similar to Sh. Satish Kadam of Ratnagiri, Maharashtra dated 2nd May 2008.

I am from Satara District, (At Post Bamnoli, Tal. Jawali, Dist. Satara, PIN – 415514).  We were drilled borewell on 21st April 2008 for agriculture purpose (1 acre plot and 1 acre about ½ km away).  The water diviner shown the point and assured water at 40 foot and 3 HP electric motor will be operational for 24 Hrs.  In and around (0.5 km radius) no bore well or dug well.

Very next day we started the work.  In between 35 - 40 foot some quantity of water came up (driller told it is 1 inch water).  Then the driller put casing of 43 foot from ground level and we kept the drilling continue.  With the hope to find water we decided to drill more foots. From  40 - 50 foot hard rock started, in between 160 – 165 foot  read soil (~ 1 foot layer) found, further we go up to 300 foot but no water found. Hard rock and only dust is appeared during the drilling.  After 15 days, we checked by putting a rope in well to check the stored water level.  But up to 210 foot there is no water stored.

I would like to know -

•    Due to casing the water found at 35 – 40 foot has blocked?

•    How to release the water, if it is blocked by casing?

•    Shall I go for bore blasting?  How much it will cost?  Is it any expert in our district?

•    Is it water level increases in other seasons (other than summer)?

•    How to utilize this drilled bore or shall I give up?

By reading the information furnished by Madhukar Tarade both as text and Excel drawing at
http://www.indiawaterportal.org/blog/wp-content/uploads/2008/05/how-to-utilise-dry-borewell.xls in conjunction with several such queries that appeared in this forum, the need of the hour for the government is to create a competent extension service to prevent farmers from committing costly mistakes in faulty well construction operations and to help them to develop the available groundwater in a cost effective manner. No wonder there are so many suicide deaths among the groundwater-dependent farmers of India!

Based on an interpretation of the information made available and that made available at
http://www.maharashtra.gov.in/english/gazetteer/SATARA/gen_geology.html published in 1963, I make the following observations.

1. The driller could not let the one-inch water obtained between 35 and 40 feet into the bore well as such an attempt would have collapsed the bore. He had to install casing pipe till 43 feet to prevent the surrounding loose material from entering the well.

2. The rock encountered between 45 and 300 feet is evidently Deccan Trap/Basalt with two one-foot thick red soil carrying no groundwater. Geologists call this red soil as 'red bole'.

3. There is no deep groundwater available in and around the land. The bore well should be sealed properly and abandoned.

4. There is however shallow groundwater available in his land up to at a depth of 45 feet. If he can get the services of local well sinkers and has resources, he can construct a 45-feet dug well with well steining. To keep the cost low, the diameter should be kept as small as practicable.

Dear Madhukar Tarade,

It is difficult to give any opinion unless the site is visited. However the case referred is a typical example of ground water occurrence in basaltic terrain.

In fact if water is substantial in the top zone it can't be completely blocked by the Casing. Some time these bore wells can be seasonal in nature and may yield water in rainy season or even up to the month of November or December.

Local geologist from water supply department ZP Satara can be consulted for the rejuvenation or source strengthening of this well. Further GSDA Pune can be contacted to get opinion on the bore Ballasting or any other source strengthening measures. The Detail address of GSDA Pune is given below:

Regional Deputy Director,
Groundwater Surveys & Development Agency, Bhujal Bhawan, S.No.53A/1/4,Wakade Wadi Road, Shivaji Nagar, Pune-411 005.
Phone 9520 25521852

Hope the above information will be useful.

With warm regards,
