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
