Well Drilling in Wilson County, TN: Cost, Depth & Permits

Local Help in Wilson County, TN

Wilson County — Lebanon, Watertown, and the Mt. Juliet fringe — sits in Tennessee's Central Basin, on the limestones the USGS groups as the Central Basin aquifer system. The Lebanon Limestone is even named for rock exposures at Lebanon. Groundwater here moves through solution openings along fractures and bedding planes rather than through the rock between them, so yields can change sharply over short distances — records from nearby wells are the best guide.

Where utility water lines don't reach, Wilson County homesteads, farms, and large-lot builds rely on private wells. Requests here cover drilling, urgent pump repairs, and water-quality work in limestone country; Tennessee licenses well drillers and pump installers, so ask for the license.

What Drives Pricing Here

Depth, by our calculator method: TDEC's well database puts the median depth of the 322 Wilson County wells drilled since 2016 at 200 ft. At our calculator's limestone (sedimentary) rate of $35–$55 per foot plus $1,500–$4,500 for the permit, pump and pressure tank, our estimate for a 200-ft well is $8,500–$15,500.
Yield risk: TDEC's records show a median reported yield of only 5 gallons per minute, so ask how the quote handles a low-yield bore or a deeper hole.
State Notice of Intent fee: $75 per property site under Rule 0400-45-09-.10, filed on TDEC's CN-1240 form.
Water treatment: limestone-aquifer water carries calcium and magnesium, so budget for a hardness and iron test, and possibly a softener.
Karst channels can carry surface water to a well, so casing and wellhead sealing carry real weight here.

Permits & Local Rules

Step 1, hire licensed: Tennessee's Water Well Act (T.C.A. § 69-10-101 et seq.) requires anyone drilling a well, or installing a pump or treatment device on one, to be licensed through TDEC's Division of Water Resources.
Step 2, file the Notice of Intent: before drilling, the owner or driller files TDEC form CN-1240 with a $75 fee per property site (Rule 0400-45-09-.10). The notice expires after 180 days.
Step 3, build to the rule: Rule 0400-45-09-.10 sets the water source at least 19 ft below ground, watertight casing from at least 19 ft down to 6 in. above grade, and at least 50 ft from a septic tank or drain field.
Step 4, get the report: within 60 days of completion the driller files a Tennessee Water Well Drillers Report (CN-0825) recording depth, casing and yield. Ask for your copy.
Step 5, test: Tennessee doesn't require testing of private wells, but TDEC strongly recommends a bacteria test every year.
Wilson County is served by TDEC's Nashville Environmental Field Office, 711 R.S. Gass Blvd, Nashville; (615) 687-7000.

Geology & Water Table Notes

Central Basin limestone: USGS says groundwater here is stored and moves almost exclusively in solution openings, so depth and yield can differ sharply between neighboring parcels.
USGS describes Central Basin groundwater as typically calcium or calcium-magnesium bicarbonate water — the minerals behind hardness. Test hardness and iron before choosing a softener.
USGS reports that contaminated and turbid water are common problems in these limestone aquifers, because sinkholes and solution-enlarged fractures let surface water recharge them quickly.
Cedar glades — limestone at or near the surface under thin soil — are a Wilson County signature; the Cedars of Lebanon Natural Area is part of the largest contiguous cedar glade-barrens complex in public ownership.
TDEC's well database lists 4,375 Wilson County wells with a median depth of 160 ft; half fall between 105 and 220 ft. The 322 wells drilled since 2016 have a median of 200 ft, and the median static water level across 1,989 records is 50 ft.
Limestone bedrock sits at or near the surface across the cedar-glade zone in the county's south and east, so casing is short and the borehole is in rock almost from the start.

$Three side-by-side cross-sections of drilled wells. In sand and gravel, the casing runs to the bottom and a well screen lets water in while holding back sand. In sedimentary rock such as limestone, sandstone and shale, the casing runs through the soil into the rock, with an open hole below. In granite or other crystalline rock, a short casing is seated in hard rock and water enters the open hole through fractures.$

Local geology sets how a well is built: wells in sand and gravel are cased to the bottom with a screen, while wells in rock are cased into bedrock and draw water from fractures.

Mark a no-water pump problem in Wilson County as an emergency and mention livestock water needs. Response depends on provider availability.

Wilson County FAQs

Why can't anyone tell me exactly how deep my well will be?

Water in Wilson County's limestone moves through solution openings along fractures and bedding planes, and USGS notes the rock's properties change a lot over short distances. Most wells in these aquifers run 50–200 feet deep per USGS, but yours depends on where the bore meets an opening. Nearby well records narrow the odds, so quotes are properly ranges, not promises — get the per-foot terms and a low-yield plan in writing.

Our well water turns cloudy after big storms. Should we worry?

Yes, enough to act. USGS notes that in these limestone aquifers, sinkholes and solution-enlarged fractures let surface water reach wells quickly, and turbid or contaminated water is a common result. Test for bacteria; TDEC advises disinfecting the well and retesting after a positive result, and permanent disinfection equipment may be needed if bacteria keep returning. Have the wellhead and seal checked too.

Do I need a permit to drill a well in Wilson County?

Tennessee handles it at the state level: a licensed driller is required, and a Notice of Intent (TDEC form CN-1240, $75 per water well) is filed before drilling. Within 60 days of completion the driller files a Water Well Drillers Report with TDEC. The state doesn't require testing of private wells, but TDEC strongly recommends a bacteria test every year.

How can I see records for wells near my property?

TDEC runs an online Water Well Map Viewer intended to help private well owners and drillers look up water well data. For your own well, the driller files the state Drillers Report within 60 days of finishing — ask for a copy, since it records depth, casing, and yield.
