Design water borehole/Water Borehole Drilling Uganda Company/Pakast Technical Services

Описание

In the previous series we discussed in detail in which rocks the water is. Now we are going to design the structure of the water borehole. The most important parameters on which the cost of a borehole depends are its length and diameter. Justification of the minimum diameter of the casing screens, which ensures the design selection and the allowable reduction, allows to reduce the cost of the well, taking into account the fact that modern borehole pumps provide a wide range of capacities and pressures at a small outer diameter. The cost of a borehole pump will also depend on several factors: the type of pump, the capacity and the diameter, and an increase in diameter will lead to a price increase. Based on the criteria of water entry speed in the screen of 1.5 feet per second, we can recommend to use a four-inch column, for boreholes with a design capacity of up to 25 cubic meters per hour, which will provide the required productivity for many private boreholes in Uganda. The final decision should be made by taking into account the real hydrogeological conditions of the projected well. An eye-opening example of pumping equipment for a four-inch borehole is a three-inch solar aquifer pump. You can contact the office of a professional drilling company PAKAST TECHNICAL SERVICES to get more information about the cost of drilling boreholes with a four-inch casing running, and the cost of a three-inch pump of a solar water system.
