Water that we drink may originate from underground aquifers running through the soil and rock strata. The installation of a productive water well is as much an art as a science to locate and screen a well in a water bearing layer, and requires an experienced driller to install an effective well in an aquifer that will produce the necessary volume of water. Maintenance of pumping systems is also required for effective well use. CGCG is also experienced in well maintenance and rehabilitation.
