With 15 years of experience, our serve the irrigation and water service needs in Middle East with the highest quality service and workmanship guaranteed to your satisfaction.

This experience in the water well industry has positioned ourcompany as the leader in Water Well drilling techniques and design services unsurpassed in the areas we Serve.

Water well drilling specialists are known for complete pump systems and installations executed with excellence by scheduling a consultation.

With the use of modern, high capacity Rotary and DTH drilling equipment, we can drill water wells to meet your specific requirements, safely and efciently. Borehole diameters from 4” to 100”, (101.6mm to 254mm).

Our knowledge and experience of drilling water wells through various geological conditions ensures that we can provide a sustainable supply of safe drinking water for your use.

Water wells typically range from 3 to 350 metres (9.8–1148 ft) deep, but in some areas can go deeper than 900 metres (3,000 ft).

Rotary drilling machines use a segmented steel drilling string, typically made up of 6 metres (20 ft) sections of galvanized steel tubing that are threaded together, with a bit or other drilling device at the bottom end. Some rotary drilling machines are designed to install (by driving or drilling) a steel casing into the well in conjunction with the drilling of the actual bore hole. Air and/or water is used as a circulation fluid to displace cuttings and cool bits during the drilling. Another form of rotary style drilling, termed ‘mud rotary’, makes use of a specially made mud, or drilling fluid, which is constantly being altered during the drill so that it can consistently create enough hydraulic pressure to hold the side walls of the bore hole open, regardless of the presence of a casing in the well. Typically, boreholes drilled into solid rock are not cased until after the drilling process is completed, regardless of the machinery used.

At the bottom of wells, based on formation, a screening device, filter pack, slotted casing, or open bore hole is left to allow the flow of water into the well. Constructed screens are typically used in unconsolidated formations (sands, gravels, etc.), allowing water and a percentage of the formation to pass through the screen. Allowing some material to pass through creates a large area filter out of the rest of the formation, as the amount of material present to pass into the well slowly decreases and is removed from the well. Rock wells are
typically cased with a PVC liner/casing and screen or slotted casing at the bottom, this is mostly present just to keep rocks from entering
the pump assembly. Some wells utilize a ‘filter pack’ method, where an undersized screen or slotted casing is placed inside the well and a filter medium is packed around the screen, between the screen and the borehole or casing. This allows the water to be filtered of unwanted materials before entering the well and pumping zone.
