The best way to find out whether water is available in your land is to investigate using any geophysical techniques adopted by a qualified hydro geologist. We offer the service of Experienced Senior Ground Water Surveyor's crew for finding most suitable site using the latest Computerized Sound Survey Systems. Their findings are 90% accurate.

A borewell is drilled with casing pipe put only up to the soil-rock boundary and this is done normally for shallow depths in hard rock or in crystalline rock. But in a tubewell, the casing pipes are put up to the bottom of the borewells, with perforation in the pipes in some level. Normally the Tubewells are drilled in sand and gravel where the availability of water is much below the ground level.

Filterpoint Wells, Hand bore wells, Calyx wells and Rotary Wells are diffent types of Tube wells. Filterpoint Wells are done in the costal areas ranging from 10 ft – 40 ft. Hand bore are manually drilled tube well which may range from 20 – 200 ft. in depth and 4”- 8” in diameter. Most of the hand bore wells need periodical cleaning/Flushing. Rotary wells are constructed using seperate Rotary Rigs which range from upto 2500ft depth with 30” diameter. It is usually done in salinity areas. Calyx Wells is a miniature type of Rotary well which is inaccessible to Rotary rigs. The depth varies from 100-600 ft. and the diameter is from 5”-12”.

While drilling a borewell 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 borewell. These Pipes are fixed inside the hard rock under the soil. Casing pipes are of 4 - 8 Kgs. Some of the contractors compromises with this casing pipes to reduce drilling cost. We discourage it. Because it will lead to future problems like bore silting, muddy water etc. Filtering can also be done to prevent muddy water and for getting surface yield. Borewells 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. Dont allow small children to play near the borewell which had a larger diameter, more than 6". Periodical cleaning must be done to retain yield and quality of water. We recommend to use high quality ISI mark casing pipes with correct measurement & thickness for long life of borewells.

Ancient techniques utilized driving of tubes inside the earth to drill well using mud or water as a liquid media. Then after the invention of diesel engines, rotary drilling was used to remove cores out of the earth. This was called calex method. There are several methods used for drilling Borewell. Most commonly used are Compressor Drilling, Manual Drilling and Rotary Drilling+. Compressor Drilling is done with the vehicle fitted with High Power Hydraulic Air Compressor Machine. It is commonly used to drill on soil surface and hard rock. Another method is by manual Drilling or Hand Bore. This is most suited for lands with Clay or Sand. All these drillings will be at 4 ½”, 5", 6½”, 7" & 8½" Dia. Air compressors and pneumatic drilling equipments are used to drill borewells up to 3000 feet. The rates for drilling a borewell depends on the location, nature of soil and availability of water.
