200-Foot Well Drilling Cost

Why 200 feet is the most common residential well depth

Two hundred feet works in more places than any other single depth. In the southern Appalachians, the bedrock-aquifer fracture zone usually sits between 150 and 300 feet. In the Texas Hill Country, the Edwards-Trinity aquifer routinely yields at this depth. In the Carolinas Piedmont and Georgia, the weathered-rock-over-fresh-rock transition that produces residential water is most reliably hit between 180 and 240 feet. In the Ohio and Mississippi valleys, alluvial aquifers below the deep clay deliver good water from 100 to 200 feet. Stacked together, these regions account for most of the residential drilling in the United States, and 200 feet is the depth that captures the largest share of jobs.

The NGWA cost-of-doing-business surveys use the 200-foot mark as their reference residential depth for exactly this reason. Per-foot rates quoted in trade publications usually assume this depth. When a homeowner reads "well drilling costs $30 to $45 per foot in 2026", that quote implicitly assumes a 200-foot well in moderate geology. Above or below that depth, the per-foot rate moves: mobilisation amortises differently, the rig configuration may change, the casing fraction of the bore shifts.

Practically, this means a 200-foot bid is the easiest to compare across drillers, the easiest to benchmark against survey data, and the easiest to value as a homeowner. Bids on shallower wells (where mobilisation dominates) and deeper wells (where day-rate vs footage-rate logic shifts) are harder to read.

Cost breakdown line by line for a representative bid

Take a 200-foot well in the North Carolina Piedmont, drilled through 40 feet of clay-over-saprolite into 160 feet of fractured granite-gneiss. Six-inch steel casing is set 40 feet to seal off the clay-and-saprolite zone, then 160 feet of 6-inch open bore through the bedrock. Grouting is bentonite, 0 to 30 feet. A 1 HP submersible pump is set at 180 feet on plastic drop pipe. A 44-gallon pressure tank is plumbed in the basement.

Line items at 2026 rates. Mobilisation $800. Drilling 40 feet through clay at $35 per foot ($1,400). Drilling 160 feet through granite at $52 per foot ($8,320). Six-inch steel casing 40 feet at $16 per foot ($640). Grouting 30 feet, $400. Well cap with pitless adapter, $250. Development 4 hours, $500. Submersible pump 1 HP with control box, $1,500. Drop pipe and electrical 180 feet, $700. Pressure tank 44 gallon with switch and fittings, $700. Trench from well to house 150 feet, $600. Permit and water test $250. Subtotal: $16,060. With 10 percent contingency, $17,666. That is a fair upper-middle bid for hard-rock Piedmont in 2026.

The drilling component alone ($9,720) is about 60 percent of the total. Casing, grouting and the pump-tank package together ($3,540 + $700) make up another 25 percent. Everything else (mobilisation, development, permit, trench, contingency) is the remaining 15 percent. Knowing that ratio helps spot bids where one category is wildly out of proportion: a bid where casing is 25 percent of the total instead of 10 is either using premium materials (worth asking about) or padding the line item.

Geology determines almost everything

At 200 feet, geology is the dominant cost variable. Compare two 200-foot bids in different ground:

Florida (Floridan limestone aquifer at 150 to 200 feet). Drilling at $32 per foot through the karst limestone, $6,400. Four-inch PVC casing 200 feet at $8 per foot, $1,600. Grouting, screen, cap, $700. Pump 0.75 HP, $1,200. Drop pipe and electric, $500. Pressure tank, $550. Trench and permit, $700. Subtotal: $11,650. A 200-foot well in central Florida lands $11,000 to $14,000 installed.

New Hampshire (granite bedrock from 30 feet down). Drilling at $58 per foot through 170 feet of granite (with 30 feet of casing-driven cost), $9,860. Six-inch steel casing 40 feet at $16, $640. Grouting, cap, $600. Pump 1 HP, $1,400. Drop pipe and electric, $700. Pressure tank, $700. Trench and permit, $700. Subtotal: $14,600. A 200-foot well in granite-belt New Hampshire lands $16,000 to $20,000 installed.

The Florida well delivers more water per gallon-per-minute pumped (karst is high-yielding) at lower cost; the New Hampshire well delivers less water (granite fracture flow is unpredictable) at higher cost. This is the geology penalty in raw terms.

Casing depth at 200 feet

How much of the 200-foot bore is cased depends entirely on the ground. Three patterns:

Full-length casing (sand, gravel, alluvial). All 200 feet cased, usually 6-inch steel (or 4-inch PVC where code allows). Casing alone runs $1,200 to $4,000. Required because unconsolidated material collapses into the bore the moment the bit pulls out. Common in Florida, the Mississippi valley, glacial-deposit areas of the Upper Midwest.

Surface casing only (hard bedrock). 20 to 60 feet of casing through the upper weathered or saprolite zone, then 140 to 180 feet of open bore through the bedrock. Casing runs $400 to $1,200. Common in New England, the Carolinas Piedmont, the Appalachians, the interior West.

Mid-depth casing (mixed geology). Casing extended to seal off a problematic zone (a salty intermediate aquifer, a layer of contaminated water, a fractured shale that produces bad water). Casing depth could be anywhere from 60 to 180 feet. Common in regions with stratified aquifers; the driller decides based on cuttings and water-quality samples taken during drilling.

Pump and pressure tank sizing for 200 feet

The pump for a 200-foot well does two jobs: lift water about 200 feet (vertical column) and deliver enough flow at sufficient pressure to run a household. The standard sizing for a 3 to 5 person household is a 0.75 to 1 HP submersible pump capable of delivering 10 to 12 gallons per minute at 50 to 60 psi at the wellhead. That sizing assumes a static water level of 30 to 80 feet (typical for a 200-foot well in moderate geology) and a working pressure-tank cut-in at 40 psi and cut-out at 60 psi.

Jet pumps do not work at this depth. The 25-foot suction-lift limit (a physical constraint of pulling water up through a pipe with surface-level vacuum) rules out any above-ground pump for 200-foot service. Submersible is the only option. Choices within submersibles come down to 2-wire vs 3-wire (3-wire has the starting capacitor in the control box at the surface, easier to service; 2-wire has it integrated in the pump, simpler installation), stainless-steel vs cast-iron casing on the pump motor (stainless lasts longer in mineralised water), and brand (Goulds, Franklin Electric and Grundfos are the three commonly specified in the United States).

Pressure tank sizing matters more than people think. A 32-gallon tank delivers about 10 gallons of usable drawdown; a 44-gallon delivers 14; an 86-gallon delivers 28. The bigger the tank, the less the pump cycles, the longer the pump lasts. For a 200-foot well with a 1 HP pump, the 44-gallon tank is the sweet spot: extra $150 on the tank, extra 5 years on the pump (which costs $1,500 to $3,500 to replace at this depth). The arithmetic favours the bigger tank.

When a 200-foot well disappoints

The classic 200-foot disappointment is the low-yield bedrock well: the bit reaches 200 feet, the bore produces 1.5 gallons per minute, and the homeowner has paid for a well that cannot reliably support a household (the rule-of-thumb minimum is 3 gpm sustained or 5 gpm peak with a pressure tank). Three options at that point: hydrofracture (described in well hydrofracturing) at $1,500 to $4,500, which historically lifts yield in fractured-rock wells by 2x to 4x with a 70 to 80 percent success rate per NGWA guidance; deepen the well at $40 to $60 per additional foot (covered at well deepening vs new well); or add a storage cistern at $1,500 to $3,500 to time-buffer the low yield.

For most bedrock-well homeowners, hydrofracturing is the right first move. It is cheaper than deepening, has a high success rate, and only adds a half-day to the project timeline.
