Circular 1/CH166: Design and Construction of Screened ...

It is best to control sand at the well screen or gravel pack. A 2,000-gpm irrigation well operated 800 hours per year with 20 ppm sand in water will remove about 7 tons (or approximately 4.5 cubic yards) of fine sand from the water-bearing strata. In many cases, proper well design and development can prevent sand from being pumped.
