Hi,

My Name is Harish. Recently I have drilled a borewell for residential use up to 1271 Feet. After drilling the borewell we left for 30 days and did camera scanning to check for water sources. We found one water source at 150 Feet (Water was flowing) and one empty source at 300 Feet (No Water). Water storage at 700 Feet. Camera scanning guy left the camera inside the water and told us that there are more water source inside you will be able to extact water 1" inch or 1.5" inch of water hence we brought 7.5 HP pump (75 stages) with 1" inch HDPE pipe and fixed the motor at 1200 Feet. First one water flowed for about 3 hours and stopped we thought everyday we will get water for 3 hours however next day we got only for 45 mins and it stopped after 3 hours again we will get for 45 mins. One of the guys suggested to change the mouth of the outflow from 1" inch to 0.5"inch you get water continuously. We did that and now water is flowing out only 0.5"inch and rest remained in the pipe and it is flowing back to borewell. From this we are getting water in full force for 1 hour and force of the water get reduced. I check the AMP and voltage consummation. Initially one hour it will be 10 AMP and voltage will be around 380-400v after one hour it will come down to 6 AMP and voltage will be around 220-240v. I am using Texmo motor and L&T starter.

My question - will this effect my motor life? will this damage my pipe?

Any suggestion are welcome

Thanks
Harish N

Hello sir, please advice me about a typic issue in my bore well.

I am having a problem with my bore well at home. .Its a new bore that we have drilled to 500ft and sent a sub moto inside upto 480ft. We get a min water for house use only. Some times 20min in the morning. The water level is low at my site.

But my problem is, the very 1st pipe that connects to my Submerge moto always gets bulged and burst at the middle of the pipe. What could be the reason. My bore technician also says that he has not come across this issue in his whole experience. This has happened 2 times now in 1 month itself.

dear friend,
In Bangalore we have a person calledJaffer, who gives the service of taking a video of the bore by sending a video camera upto a depth of 1600 feet.
While doing so he also gives you the health status and remedial actions if required.
his mobile number is 8317380071 and 9341948981.
I have taken his help for 4 of my Borewells and found him to be quite knowledgeable.

Sir my borewell is pumping water for 20min
Stops pumping after that
After 1hr again it pumps for 20min
What may be the problem

The reason of stopping water some Time after getting some time Must be there is no sufficient water in the Borewell. To asses correctly , kindly provide the following DATA.

  1. Total Depth of Borewell.

  2. Casing Pipe Length

  3. Yield of Water if assessed after Drilling.(If avilable)

  4. Drawdown Level of the Borewell (If taken after Drilling while Flushing)

  5. H.P. of the Pumpset with Brand and Number of Stages.

  6. Level at which Pumpset was inserted i.e. Delivery Pipe Length.

              On getting the above DATA we can advise  some extent
