Once the well is developed we run a pumping test, recording gallons per minute and how quickly the water level recovers after pumping stops. That number, not the depth, is what tells you whether the well will keep up with a household. A low-yield well is not automatically a failed well - paired with a storage tank and a controlled pump cycle, a well producing as little as one or two gallons a minute can serve a household comfortably. We size the storage to the actual number, not a hopeful one.
Quantity and quality are separate questions. Every well we complete gets a post-drilling water test for bacteria, plus the minerals that cause problems locally - iron, sulfur, and hardness. A deep well is not automatically a clean well; depth tells you nothing about water quality on its own. Treatment is matched to what the test actually finds: a softener for hardness, filtration for iron or sulfur odor, ultraviolet disinfection where bacteria shows up. We do not sell a whole-house treatment system before we know what is in the water.
A submersible pump is sized to the well's depth and measured yield, feeding a pressure tank and switch through a pitless adapter at the casing, with wiring and controls run to the house. Undersizing the pump to save money is the single most common reason a new well disappoints its owner. Existing wells are most of our repeat calls: a pump that has failed, a waterlogged pressure tank cycling too fast, or yield that drops in a dry summer - we diagnose on site before replacing anything.
We pull the drilling permit, and the completed well log - depth, casing, formations, and the yield test - is filed with the state and given to you for your records; it is the document a future buyer or lender will ask for. An old or abandoned well on the property is usually a legal requirement to seal, not an optional cleanup, since an open, uncapped borehole is a direct path for contamination into the aquifer. We grout and cap abandoned wells to code and file that paperwork too.
