What is the main function of a well screen?

The main function of a well screen is to prevent sand and other particulate matter from entering the well. A well screen is designed with small openings that allow water to flow into the well while keeping out larger particles, such as gravel, sand, and silt. This critical feature helps to ensure that the water extracted from the well remains clear and free from sediment, which can lead to clogging of pumps and a decrease in water quality.

The design of the well screen is essential in maintaining the integrity of the overall well system. When sand and debris are successfully filtered out, it ensures that the water extracted is potable and reduces wear and tear on well equipment. The well screen's ability to effectively filter out unwanted materials directly impacts the efficiency and longevity of the well, making it a vital component in water supply systems.
