Well rehabilitation is the process of restoring or improving the performance of a water well. Over time, wells can experience reduced water flow due to various factors such as clogs, mineral deposits, or changes in the surrounding aquifer. Here are some key aspects of well rehabilitation:
Cleaning and Maintenance: Regular cleaning is essential to remove accumulated debris, sediment, and biological growth within the well. Contractors use brushes, high-pressure jetting, or surging techniques to clean the well casing, screens, and other components.
Hydrofracking: Hydrofracking (short for hydraulic fracturing) involves injecting high-pressure water into the well to create new fractures or enlarge existing ones in the surrounding rock or soil. This process can improve water flow by allowing fresh water sources to replenish the well.
Chemical Treatments: Specific chemicals can be used to address different issues, including slime and iron bacteria, scale related clogs, and persistent bacteria problems.
Assessing Water Quality: During rehabilitation, water quality is evaluated to ensure it meets health and safety standards..
It is recommended that you have a professional well contractor perform any well rehabilitation to ensure that the integrity of your well is not jeopardized during the process.
