Proper well design and construction is essential to the reliability of a groundwater supply system, and can significantly improve well yields, extend well life, and reduce operation and maintenance costs.
When our well design experts approach a well design project, they consider a number of factors—local hydrogeologic setting and groundwater conditions, desired well yield, drilling contractor experience and equipment availability, design life, and economic feasibility. Hydrogeologic considerations for well design include:
- The nature of the geologic materials forming the aquifer
- The depth and thickness of the aquifer and overlying materials
- The depth to groundwater
- Water quality
- Seasonal and long-term water level changes
- Interference from nearby wells
- Connection to nearby surface water
GSI’s experts have designed well specifications and provided construction oversight for numerous groundwater supply and ASR wells, with capacities ranging from 25 to over 5,000 gallons per minutes (gpm). We are experienced in designing wells in alluvial and glacial sedimentary aquifers, as well as in basalt and other types of bedrock formations. We work on everything from small production wells that maximize production in low-yielding, limited aquifers to complex wellfields with multiple high-capacity wells, requiring aquifer mapping and groundwater flow modeling.
