Well Drillers Near Flint, Michigan

A typical residential well in the Flint area is drilled to approximately 160 feet to ensure a reliable water supply of 5-15+ gallons per minute.

The static water level, or water table, is typically found around 37 feet below the surface in this region.

The average subsurface profile in the Flint region begins with 10–20 ft of surficial sand or sandy clay, followed by 40–60 ft of predominantly clay (often blue/gray or brown with occasional sand or gravel interbeds). Below ~70–90 ft, there is a variable interval (20–40 ft) of sand, gravel, or both, with additional thick (>40 ft) clay, and then a consistent transition to shale and sandstone bedrock between 110–125 ft, extending to at least 180–220 ft. Most potable water is drawn from bedrock (shale and/or sandstone), with static water levels typically 20–45 ft below grade. The primary drilling method is rotary with bentonite slurry grouting commonly to 80–150 ft. PVC casing (5 in.) is regularly installed to similar depths, stopping at or above the bedrock interface. Typical residential wells are finished at 120–180 ft, yielding 7–15 GPM, while higher capacity or deeper wells may approach 200+ ft.
