What care must be done while bore well drilling?
A: While drilling a bore well we have to insert pipes called Casing pipes. It can be PVC/GI. This is done to prevent the Surface water with Sand from entering inside the bore well. These Pipes are fixed inside the hard rock under the soil. Casing pipes are of 4 – 8 Kg. Filtering can also be done to prevent muddy water and for getting surface yield. Bore wells must be kept closed to prevent something to fall inside it and block the bore. Pumps must be installed as soon as possible to avoid bore silting and damage.
Q: Did all bore well yield water?
A: According to us most of the bore wells yield water. Only a few of them were dry. We had drilled 85% of bore well with high yield 10% with good yield & 5% with no yield. Our Water divining success rate is 90% – 95%. We recommend clean/flush your bore well on every 5 year to retain the yield & quality of water.
Q: What types of Pumps are used in bore wells?
A: Most commonly used pumps for bore wells are Submersible pumps, Hand pumps and Compressor pumps. All types of pumping systems from 0.25 mono blocks to 50 HP Submersible pumps, Mono blocks, Centrifugal jet, Bore well submersible, Compressor pumps, Hand pumps, Solar Submersibles, Pressure boosters, Piston Pumps, Turbine pumps etc. can also be used. It depends upon the availability of water & the depth of bore well.
Q: How testing is done during bore well drilling?
A: Testing can be done for checking the discharge quantity of water from the bore well. We have the professional geologists for testing and they will recommend the pump suitable for your bore well.
Q: Is bore well water pure for domestic use?
A: The bore well water is purer than Fresh River or lake water. It will still have dissolved solids and salts and minerals. Some of the bore well water will be hard water. It is advisable to test the bore well water before drinking, if you have any doubts on its freshness.
Q: Is there a best suited time for drilling a bore well?
A: As such there is no prescribed season for drilling a bore well if the location of site has adequate ground water potential. However, identifying a suitable site and drilling the bore well in summer months would give the worst possible scenario in the location at the point of time. Therefore, summer months are usually preferred by some experts as the best suited period for drilling a new bore well. Also, as most agricultural sites can be accessed by drilling rigs only during summer months, they are usually available in these periods.
Q: How are charges for drilling a bore well calculated?
A: Charges for drilling a specified size of bore well include, drilling cost per feet, cost of casing pipe per feet, cost of drilling and installation charge for casing pipe per feet, flushing charges per hour for flushing the bore well after drilling and transportation charges of the rig to the site from nearest town per km.
