Puurkaevude

Puurkaevude, often translated as drilled wells or boreholes, are a common method for accessing groundwater. This process involves drilling a hole into the ground to reach an underground aquifer, from which water can be extracted. The construction of a puurkaevude typically begins with drilling a pilot hole to determine the depth and characteristics of the aquifer. Once the target depth is reached, a casing, usually made of steel or PVC pipe, is inserted into the hole to prevent collapse and contamination. A screen is then placed at the bottom of the casing, allowing water to enter the well while filtering out sand and gravel. A submersible pump is then installed to lift the water to the surface. The diameter of the puurkaevude can vary depending on the intended use, ranging from a few inches for domestic supply to several feet for industrial or agricultural purposes. The depth also varies significantly, depending on the local hydrogeology and the depth of the desired aquifer. Regular maintenance, including pumping tests and water quality analysis, is essential to ensure the long-term performance and safety of a puurkaevude. Improperly constructed or maintained puurkaevude can pose risks of groundwater contamination and depletion of water resources.
