Introduction:
In water well construction, screens and liners are crucial to ensuring the well's longevity, efficiency, and safety. Screens are designed to allow the passage of water while preventing the infiltration of unwanted particles, such as sand or debris. They are typically placed at the well's intake zone to filter water effectively.
On the other hand, liners provide structural integrity to the well, preventing the collapse of the well casing and protecting the water source from contamination. Screens and liners help optimize water extraction while safeguarding the well and the surrounding environment. Understanding their design, materials, and installation methods is vital for building successful and sustainable water wells.
