The drilling fluid is fed into the drill, travels up the drill stem, flows through the pump, and then is discharged into the settling tank where it will cycle through once again. When cuttings are settled, drilling fluid is forced down the hole to the bit. This pressure prevents the bore hole wall from crumbling under the pressure of the fluid.
The contractor hired to drill your borehole will not guarantee that they will hit water. Their job is simply to drill a hole in the ground to the depth you have requested. You should hire a hydrogeologist if you want to minimize the risk of not hitting water and resulting in a “dry hole.” A hydrogeologist will evaluate your area and may perform physical tests on your property to determine the best spot to drill and your chances of finding water. You should keep in mind that the drilling rig is a huge piece of equipment weighing about and above 25 tons.
Would getting a borehole be a good investment? Overall – adding a borehole to your property will increase the value of your land and make a good investment over the long run. The quality of your garden is something that can contribute as much as 5-20% to the value of the property. It is a double success if you use borehole water to improve your land, as you save money on your water bill and improve its aesthetics simultaneously. Additionally, having a rain harvesting system and a borehole on your property will add value to it, so either of these features will add value to your property. In these cases, the installation must have been done by professionals and maintained appropriately.
It is important that you become familiar with borehole drilling so that you do not get taken advantage of. That is exactly what you have already done by reading this! Choosing a reputable contractor is the next most important step. You’re most likely to know what your expectations are before the work starts, and should either of you fail to address your concerns, you have the option of recourse. A contract should be used by contractors, or they should give you a quotation in which they detail the work to be done, including the delivery schedule and price. As a result, both you and the contractor will know what to expect. Before choosing a contractor, be sure to obtain at least two quotes since contractors determine their own rates. Don’t forget to look at the details and not just accept the cheapest offer! This will likely lead to complications, poor service, or even getting ripped off.
