What Does
Water Well Drilling Mean?
Water well drilling is the process of drilling holes in the earth's surface for the purpose of reaching a groundwater source. There are several water sources beneath the earth's surface but are difficult to reach and in some cases very deep. There are several drilling techniques that can be used for the purpose of drilling water wells and the most commonly used are rotary drillers that bore vertically into the earth. With the success of horizontal directional drilling (HDD) in the oil and gas industry, many in the water well industry are now turning to HDD for drilling water wells.
Trenchlesspedia Explains Water Well Drilling
Recently, HDD in water wells has fetched good results. Earlier HDD was adapted for the purpose of remediation of contaminated sites, such as for industries, military bases and gas stations. HDD has the advantage of causing very limited surface disruption and also has a favorable screen-to-riser ratio. In desert areas and coastal and island communities, the aquifers that they depend on for water supply are vertically perched, thin, shallow or are sometimes buried in streams. Using vertical wells for accessing this water is impossible. HDD is perfect for such situations as the well can be dug from another location to access the water source.
