A method and apparatus are disclosed for restoring and/or maintaining an underground aquifer water supply system plagued with decreased water flow attributable to accumulation of undesirable flow impeding agents in the aquifer wherein a plurality of injection wells are drilled in the ground in surrounding relationship to the production well and a part of the water from the discharge thereof is treated with an additive capable of altering the nature of the plugging agents and returned to the aquifer via the satellite injection wells on a continuous basis. The proportion of bypass and recycle treatment water sent back to the aquifer may be varied with up to 50% normally being recycled for well restoration purposes while only about 10% need be returned for maintenance of the well flow at a desired level.

A foraminous screening device comprising a cylindrically tubular body having a plurality of spaced apart apertures therethrough and including a network of helically shaped ribs. The network includes first and second rib sets both having a plurality of mutually parallel and axially spaced ribs therein. The ribs of the first set have a clockwise orientation and are connected at points of intersection to the ribs of the second set which are oriented in a counterclockwise direction. Each of the ribs comprises a plurality of axially disposed, overlying bundles of tensed glass filament which are interconnected and embedded in a matrix of hardened synthetic resin. The ribs are interwoven at each point of intersection, and each bundle constitutes a portion of a continuous, elongated glass filament strand.
