Borewells

Borewell water level drop, able to pump water only for 3-4 mins: Does the bore need flushing?

Hi, 

We had drilled borewell in 2003. I don't have the complete information regarding the borewell. Couple of years back, there was big hole around the borewell and mud entered into the borewell. From then on, water level started dropping. I have an immersible motor to pump water from borewell to the sump. Now there are 2 or more bores drilled by other house owners. Now I see a complete drop in water level. On powering the pump, there will be water for 3-4 min after which there will be no water. If I try after 3-4 hours I will get water for 3-4min. 

1. Is this behaviour due to the fact that the water level gone down, or,

2. Does the bore need flushing?

Can anyone visit my house and advice on resolving this issue.

Borewell collapse at 645 feet, depth of water available just 5 feet, water source appears to be connected to another borewell: Will further drilling help?

Hi,

My house construction (in 30x40 site) has started and now its at the foundation level. We had drilled a borewell and the information is as follows,

Borewell location : K.R.Puram (Mahadevapura), Bangalore East
Drilling time: Mid November, 2011
Depth of borewell : 650 feet
Depth of 6.5 ” casing : 80 feet
Depth of 10" PVC Casing pipe: 10 feet.

Yield data - I yield: 640 feet, 2.5".

On further drilling, boulders were found at 645 feet. and we continued to drill till 660 Feet.
It was meant to be used during the house construction. Now, before inserting pump we checked with a camera and found that the well has collapsed at 645 feet onwards and the depth of water we have is just 5 feet. Also looks like water source is connecting to another borewell, as water is not rising above 640 feet though we had 2.5" to 3" water during drilling.

Can you please advise whether drilling for another 100 to 200 feet will help?
Is it possible to install PVC filter pipe from 640 onwards using any method after re-drilling for another 100 t0 200 feet?
Any solution will be greatly appreciated.

Regards

1/2" water in borewell at 150ft: What is water availability per day from this quantity

Dear Sir,


I am from Bhubaneshwar. We dug a bore well (Depth-270ft). We got a hint of water at 120ft and at 150ft we got about 1/2" water and even lesser water at 180 ft. But after that there is no sign of water. I asked the engineer to do a test and he said not much water is available at the site. He asked us to manage with that much water. I want know how much water we can get per day with 1/2" at 150 ft. We are 7 people staying at home and would like to know if that amout will be sufficient.

Query : About borewell minimum distance from openwell

Hello,

My farm is in north Konkan - Raigad district. The soil is lateritic. It is on a plateau, but at the base of a 40m high ridge which forms the catchment area.

Eventually, I intend to dig an openwell, but due to some restrictions initially I decided on a borewell. The question is, how far should my borewell be from the proposed openwell so that it does not affect the inflows into the well. The openwell spot gets inflows from all directions (N, E, W, S) and the borewell is a little upstream on one of the sides of the openwell.

Do you think a distance of 200m is sufficient buffer between the 2 wells?

Looking forward to your advice.

Thanks.

How to remove yellow color & salty taste from bore well water?

I am living in Ramapuram, Chennai. In my house the bore water is yellow colored, salty & it contains 2500 TDS. The depth of the bore is 150 ft & we have put the suction valve at 140ft.  Neighbors are getting good water & they have dug only 80-90 ft of bore.

The detail of water present in our area is:

  •   20-60 ft contains yellow colored water
  •   65-100 ft contains rock – it gives colorless good water
  •   110-150 ft contains salt water

We have installed Iron remover (MnO2 used as medium) and softener. Still the output water is yellow colored & the harness is reduced.
Can you suggest ways to remove the yellow color from the bore well water?
Is there any possibility of getting good water if I reduce the suction height (80-100ft) or still I will get the same salty taste & yellow colored water?

Use & Disuse - Effects on a Borewell? - Raigad, Maharashtra

I have bought a house in the Raigad district of Maharashtra. I want to drill a borewell in empty space around  my house. But before driling, I have one important question as follows. We normally visit this place once in three months. So if we are not using this water for quite some time will it be stop flowing?

Advice required on controlled blasting technique for pump stuck in borewell

Sir,

One of the bore in our apartment is 800 feet deep while the submersible motor is immersed only to a depth of  600ft. We intended to lower the motor from the existing 600ft to 720 ft, before lowering the motor we wish to ascertain the exact depth and water springs available in our borewell by inserting an underwater camera. Once the contractor started pulling the pump, it got stuck at 575ft and now they were neither able to pull up the pump nor push it down. The contractor told us that it may be stuck in between the rocks and suggested to use control blasting techniqe to Dis-engage the Delivery pipe(PVC) from the Submersible motor. Please advise us further action as it also involves some risk of damaging our building while using control blasting technique. Is there any other way to pull up the pump? 

I have gone through similiar kind of queries (http://www.indiawaterportal.org/ask/5374 , http://www.indiawaterportal.org/ask/5318) but need some advice on control blasting techniqe or any other proved techniqes.

Thanking you,

Avinash

Improvement in bore well yield and pumping method

Dear All,

I have drilled a bore well on my six acre plot about 5 kms. from Birur town, Chikmagalore district, Karnataka, during 2007 to take up horticulture. The bore well location was identified by a geologist using electrical resistivity test. He predicted the water bearing zones at the depth of 70, 210 and 300 feet and suggested to drill upto 350 feet and predicted about 2" water yield and told me it is reliable source as it will not decline during summer. His predictions were accurate regarding the water zones, we got wet soil at 75 feet, struck water at 220 feet and water quantity improved at 300 feet, even though we continued drilling till 450 feet there was no improvement in the yield. The pvc casing pipe of 60 feet fitted, below that we got hard strata (black stone chips and white stone powder came out) the driller estimated the yield as 2.0" (eye estimation without any V notch) and suggested to use a 6 hp, 12 stage submersible pump(three phase) at a depth of 310 feet. I followed drillers suggestions and installed the pump. The pump delivers full flow in a 2" delivery pipe for initial 14 minutes, and later gives alternative supply of 1 minute 3/4th of the pipe (2" pipe) and 1 minute 1/4th of the pipe.

The water yield is same during summer and monsoon, and unchanged during 4 years of operation. 

Since water yield is low I have drilled one more bore of 350 feet depth after two years, about 100 feet from the first bore with similer yield at same depths and same geological charecters. But surprisingly this borewell has not altered the yield of the first borewell.

My question is

1) What is the yield in liters/hour?

2) Is my pump selection wrong? If so, 

a) What is the ideal pump configuration (hp, stages, depth of installation)

b) Is there any possibility of using single phase submersible pump or compressor pump, as we get only 4 hours of 3 phase and about 18 hours of single phase power supply in a day?

3) Any suggestions for improving the yield of water by hydrofracturing, rainwater recharging in the same bore?

Thanks in advance

Regards
