Well Drillers Near Sioux Falls, South Dakota

A typical residential well in the Sioux Falls area is drilled to approximately 22 feet to ensure a reliable water supply of 5-15+ gallons per minute.

The static water level, or water table, is typically found around 10 feet below the surface in this region.

The majority of water well logs from Sioux Falls show a consistent near-surface layer of fill (often silty sand or clay, sometimes with minor gravel), followed by a zone of interbedded silty sand and clay or glacial outwash (SM/CL), typically grading into a thicker, coarser, well-sorted sand or sand/gravel layer below about 9-13 ft. This basal aquifer (coarse sand or sand/gravel) is unconfined, water-bearing, and most residential or monitoring wells are set at 15 to 22 ft. Static water levels typically range from 6 to 15 ft below surface. One-off occurrences of bedrock or deeper gravels are rare within the urban area and not considered representative. Residential wells seeking 5-15+ GPM typically target the coarse sand/gravel aquifer at 18-22 ft.
