Everyday 83.3 billion gallons of groundwater are pumped in the United States. That’s approximately 2.49 trillion gallons per month, or 29.88 trillion gallons per year. Forty-seven percent of the U.S. population depends on groundwater for its drinking water supply.
Many water wells penetrate unconsolidated material and require installation of casing and a well screen to prevent inflow of sediment and possible wellbore collapse. The space around the casing is usually sealed with grouting material of either neat cement or bentonite clay to prevent contamination by water draining from the surface downward around the outside of the casing.
Well screens (filtering devices) are installed in the water bearing formations, allowing water to move into the well, while keeping out gravel and sand. The most popular filtering devices for water wells are continuous slot (wire-wrapped) screens and perforated liners.
Continuous slot screens made of V shape wire wrapped around a series of vertical rods. This allows the most inlet area and higher productions rates.
