Approximately 20 percent of the nation’s water supply is derived from groundwater. This supply is retrieved using wells and infiltration galleries. Permitting, design and construction oversight of these facilities are services offered by WWE. Appropriate design brings the right combination of drilling/construction method, material selection and design concepts together to maximize withdrawal efficiency and production from each water supply facility. In addition, WWE provides assessment of the potential influences that the water supply source (aquifer) may have on the well (e.g., water quality and permeability limitations).
