A well screen is a filtering device that serves as the intake portion of wells constructed in
unconsolidated or semi-consolidated aquifers. The screen permits water to enter the well
from the saturated aquifer, prevents sediment from entering the well, and serves
structurally to support the aquifer material. The importance of a proper well screen cannot
be overemphasized when considering the efficiency of a well and the log-term cost to its
owner.
Well screens are manufactured from a variety of materials and range from crude handmade contrivances to highly efficient and long-life models made on machines. The value
of a screen depends on how effectively it contributes to the success of a well. Important
screen criteria and functions include:
Criteria:
1. large percentage of open area
2. non clogging slots
3. resistant to corrosion
4. sufficient column and collapse strength
Functions:
1. easily developed
2. minimal incrusting tendency
3. low head loss through the screen
4. control sand pumping in all types of aquifers
