Generated explanation

A cross section shows a drilled well extending through soil into bedrock, with a submersible pump below the resting water level supplying a house. Enlarged details show the capped steel casing, slurry seal, pump wiring, and pitless adapter connecting the vertical pipe to the buried pipe to the house. The casing extends into bedrock, and water enters the lower well through cracks in the rock. A check valve is located above the pump, and clearance below the pump prevents mud pickup from the well bottom. Dimension arrows identify well depth, air above the water, static head, and pump clearance; a note describes a safety cable used to prevent loss of the pump if connections come apart.
