I have a borewell dug in my farm and the depth of the borewell is around 195 feet. I have applied for a Solar pump subsidy and I am about to get the equipment with following details:
- 4.7kW solar panels
- 5 HP 12 stage submersible water pump
- Borewell diameter - 6 inch
As I understand from the technician, this is just sufficient lift the water from the borewell. But what I plan is to lift to the highest elevation in the farm so that the water can be fed by gravity in the farm as and when needed.
In the snapshot from Google maps I have calculated the distance to 'push' the water:
So now the details are as follows:
- Depth of borewell = 195 feet ≈ 200 feet
- Horizontal distance to push water = 333 mtr = 1092 feet ≈ 1200 feet
- Number of pipe joints = Around 8 to 10
- Altitude difference between borewell point and highest elevation land = 68 feet ≈ 70 feet
- Planned elevated tank construction's highest elevation point = 20 feet
- Desired flow rate - I do not know it exactly in litres per minute but I do know that 5 HP 12 stage output is around 1 lakh litres per day, so I am ok to forgo around 50% of this to push the water to my desired location.
So the pump should vertically lift a total of 290 feet and should horizontally push a distance of 1200 feet along with around 3 joints in between.
I would like to know if the provided equipment is capable of handling lift and push of water for these distances and elevation, if not, what is the capacity I should be looking at.
Please let me know if the above details are sufficient enough. I need some scientific guidance and best practices as against the technicians guidance because they recommend out of their experience and not out of precise calculation as such.
Edit: I received the pump and solar PV specifications from technician, attached are the details:
Kindly guide me with the maximum lift for the water to higher altitudes.
