Frequently asked questions to borewell contractors

• What is a borewell?

  The borewell is bored or drilled into the ground to reach the water levels to get the quality water for domestic and commercial purposes. The borewell contractors are the professionals who drill the borehole into the spot. The borewell contractors in Delhi hold the latest technologies to spot the right place for drilling borewell.

  Most commonly, the size of the borewell ranges from 4.5”- 12”. For the domestic purposes, the sizes from4.5 -5.5 is preferred while 6.5” and more is recommended for the commercial purposes. The high-grade PVC pipes which confirm with the Bureau of Indian standards are recommended for casing as well as pipes. It is important to choose the best borewell pipes for your project. The casing is the support that secures the borehole from getting damaged.

• What is the difference between borewell and tube well?

  The pipe of the borewells is secured with the casing while for the tube well the casing is present in the bottom with perforated pipes in some levels. The borewell is drilled for shallow depths in hard rock while for the tubewell boring contractors drill in sand and gravel where the water is present deep under the ground.

• How do you find the right spot for drilling where the water is available under the ground?

  The borewell contractors hold the contacts of the local water diviners and geologist. These experts are specialized in finding the right spot for drilling. They find the right spot where the water is available under the ground. The geologists are aware of the geological composition of the land which helps him to spot the right place. There are also professionals called the groundwater surveyor crew, they make use of the latest technologies like computerized sound survey systems to identify the spot. It is said that their findings are 90% accurate.

• What are the commonly used techniques for drilling borewells?

  There are many methods of drilling borewells like compressor drilling, manual drilling, and rotary drilling. In compression drilling method, the borewell drilling machine fitted with high power hydraulic to drill into the ground. This method is meant for the soil surface with hard rocks. The hand bore is the manually drilling bore most suitable for the lands with clay soil. Some of the pneumatic drilling equipment can even drill up to 3000 feet. The borewell drilling method is chosen based on the location, nature of the soil, boring type and the availability of water.

• What should you consider while drilling a borewell?

  The casing pipes are inserted while drilling the borewell. It is important to make sure that the borewell contractor makes use of the best quality casing pipe which is made of PVC/GI. The casing pipe weights 4-8 kg and needs to be with a certain thickness. Some of the borewell contractors comprise in the thickness to reduce the cost of drilling. When the thickness is compromised, it creates problems later such as the bore silting which degrades the quality of the water. You can use filters to get a clean and clear water. Also, make sure that the borewell contractor makes use of ISI standard products for casing and also keep an eye on the measurement and thickness.

• Do all the borewells yield water?

  Most of the borewells yield water, some of the borewells yield water primarily and then dries after some time. The yield may be high, low or nothing sometimes. The yield primarily based on the many factors like the composition, water level, and the other things. The key for getting high yielding borewell drilling is to find the right spot for drilling. This is how to get water from borewells.

• Why do the borewells fail?

  Regardless of the techniques used for determining the spot for drilling, there is nothing to confirm the water yield. In some cases, deep drilling yields water while in some other cases the deep drilling ends up in facing the rocks. There are many other reasons for the failure of the borewells. The reasons may start from the decrease in the groundwater level, over usage of borewells in the nearby areas, improper selection of motor pumps and much more.

• What are the pumps used for borewells?

  The most commonly used pumps for borewells are the compressor pumps, hand and submersible pumps. Other pumps like the jet pumps, centrifugal jet, solar submersible, pressure boosters, piston pumps, and the turbine pumps are also used for borewells. The type of the pump and its capacity is decided on the basis of the factors like discharge quantity of the water and the depth of the borewell. It is important to get advice from the geologist or the borewell service provider before deciding on the right type of the pump and its capacity.

• Is borewell water usable for domestic purposes or for drinking?

  The water from the underground water levels or the bore water is purer than the fresh river and all the other groundwater. Some of the bore water may be hard water. Regardless of water from any waterbody, it is important to boil the water before drinking. You can arrange a water purifying system or a filter to clean the borewell water.

• What is open well digging?

  The open wells are one of the types of wells that is drilled on the ground with open well drilling machine to get access to the shallow groundwater in the local areas. The detailed open well estimate depends on the cost of the drilling machine, depth of the well, and many other things.
