Drilling a new water well in Central Florida is a major-purchase decision driven by depth, casing length, permit handling, and the pump-and-tank package. The honest answer to "how much" is a range, not a number, and the range moves with geology. This guide walks the real cost drivers, the realistic ranges we see across Marion, Alachua, Orange, Lake, Polk, and Volusia counties, and the questions to ask any contractor giving you a quote in 2026.
Why a Single "Average Well Drilling Cost" Is Misleading
Quote calls that promise you a fixed dollar figure for a well over the phone, with no site visit and no review of nearby well-completion records, should be a red flag. Two adjacent properties in the same Marion County subdivision can have drilling totals that differ by several thousand dollars depending on what sits between the surface and the productive aquifer zone. A 120-foot well in stable Floridan Aquifer limestone is a different project from a 280-foot well that has to case through 90 feet of unstable surficial sand before reaching usable yield.
Reputable Florida-licensed contractors quote on a per-foot basis for drilling, with separate line items for casing, grouting, pump and tank, permit fees, and well-development work. The total moves with site conditions. We publish honest ranges below; we do not publish a single number that does not exist.
Cost Driver 1: Drilling Depth
Total drilled depth is the single biggest cost line on most residential wells. The Florida Administrative Code does not set a one-size minimum depth; the contractor sets depth based on site geology and target yield. For the Floridan Aquifer across Central Florida, residential wells typically run 100 to 400+ feet. Surficial-aquifer irrigation wells can be much shallower, sometimes 30 to 80 feet.
Cost per foot varies by contractor and site, but in 2026 most reputable Florida-licensed contractors price drilling in the broad mid-double-digit dollars per foot range for routine residential bores. A 200-foot well costs meaningfully more than a 120-foot well; a 400-foot well costs roughly double the 200-foot well in pure drilling charges.
The depth bands we see by county tend to run as follows. Western Marion County (Ocala, Belleview, Dunnellon) commonly lands wells in the Upper Floridan at 150 to 280 feet, though some properties on the karst plateau need an extra 50 to 100 feet of casing to bridge cavity zones. Alachua County around Gainesville averages 220 to 350 feet for residential bores, because the upper limestone in that area sits deeper under a thicker confining unit. Lake County's chain-of-lakes corridor mixes surficial wells at 60 to 120 feet with Floridan wells at 200 to 320 feet, depending on how clean the homeowner needs the water. Polk County around Lakeland and Winter Haven sees Floridan completions from 250 to 400+ feet because the productive zone sits below thicker overburden. Volusia and Seminole counties usually fall in the 180 to 320 foot range. None of these are quotes, they are the bands we have been seeing in completion reports filed with the relevant Water Management District.
Cost Driver 2: Casing Length and Material
Casing is the steel or PVC pipe driven through the unconsolidated overburden to keep the borehole from collapsing and to seal against surface contamination. In Central Florida, casing typically runs from about 40 feet (in stable sites with shallow limestone) to 120+ feet (in deeper unconsolidated zones near wetlands or river corridors). Schedule 40 PVC casing is acceptable for most residential applications under Chapter 62-532 and is the most common material we install. Steel casing costs more and gets specified in high-traffic locations or where borehole instability is a concern.
Cost Driver 3: Permit Handling
Every new water well in Florida requires a Water Management District well-construction permit. The permit fee itself is modest (typically a few hundred dollars across the state's five WMDs), but the contractor labor to fill out the application, attach the required site plan, manage WMD response, and file the post-completion report is real work that gets bundled into the project price.
We handle the full permit package on every drilling job we do. If a contractor quotes you a well and tells you "permits are your responsibility," walk away. Florida-licensed contractors are required to pull the permit; that requirement is not transferable to the homeowner for a new water-supply well.
The WMD permit workflow for a routine residential well runs about eight steps. First, the contractor logs into the relevant WMD portal (St. Johns River, Southwest Florida, or South Florida, depending on county) and starts a new water-well construction permit. Second, the application captures the property owner, parcel ID, intended use (drinking, irrigation, or both), expected depth, casing material, and grout specifications. Third, a site plan is uploaded showing setbacks from septic drainfields (50 foot minimum), property lines, surface-water bodies, and any underground utilities. Fourth, the WMD reviews the application, typically within 3 to 10 business days for routine residentials. Fifth, the permit is approved and posted on site before drilling begins. Sixth, drilling proceeds with the licensed contractor on site. Seventh, the contractor disinfects the well and pulls a bacteriological sample for the lab. Eighth, a well-completion report is filed with the WMD documenting actual drilled depth, casing details, static water level, yield, and the bacteriological clearance result. The homeowner gets a copy. None of that paperwork should ever land on the homeowner's desk during the project itself.
Cost Driver 4: Pump and Pressure Tank
The pump and pressure tank are usually quoted as a package on a new well. A typical residential setup includes a 1/2 to 1 horsepower 4-inch submersible pump, a 30 to 80 gallon pressure tank, a pressure switch, a check valve, and the drop pipe and pump wire down the well. Pump-and-tank packages on routine residential jobs commonly run in the low to mid four-figure range installed, before any constant-pressure controller upgrade. A VFD or CSV constant-pressure controller adds several hundred to over a thousand dollars depending on the model and pump size. We cover that tradeoff in our constant pressure systems article.
Pump sizing follows a decision tree, not a guess. A 3-bedroom, 2-bath home on a typical Floridan well draws around 8 to 12 gpm peak. Cut-in and cut-out psi on the pressure switch are usually set 30/50 or 40/60. A 30/50 setting at 8 gpm peaks at about 16 amps on a 1/2 hp 230 volt submersible; a 40/60 setting and a 1 hp pump pushes that to roughly 22 to 24 amps. The pressure tank is sized to give the pump at least 1 minute of run time per cycle, so an 8 gpm pump usually pairs with a 32 to 44 gallon drawdown tank (roughly an 80 to 119 gallon tank size class). Oversized pumps short-cycle the tank and burn out motors early. We size every pump from a site walk, not from the homeowner's stated bedroom count. For the full math, see our pressure tank sizing guide.
When the homeowner needs replacement instead of new, the question shifts to whether the existing drop pipe and wire are reusable. Sound copper or stainless steel drop pipe with intact splices is normally reused on a same-day pump swap. Galvanized drop pipe over 20 years old, or PVC drop pipe with visible cracks, is replaced as part of the job. We document those decisions in writing before pulling anything. Our repair vs replace decision framework walks the full call.
Cost Driver 5: Site Geology
Marion, Citrus, and parts of Alachua County sit in karst country, where the Floridan Aquifer is overlain by cavity-prone limestone. Drilling through cavities requires careful grouting and may slow progress, which raises the per-foot cost. Wells near wetlands, rivers, or active recharge zones may need extended casing or specific construction approaches under WMD review. We discuss the karst angle in detail in well drilling in karst country.
Cost Driver 6: Water Testing and Well Development
Florida rule requires bacteriological clearance before a well goes into service. The contractor disinfects the well, pumps it long enough to clear drilling cuttings (well development), and pulls a bacterial sample for lab analysis. This is a few hundred dollars on most jobs and is usually included in the package price.
Realistic 2026 Ranges for Central Florida Residential Wells
With the caveats above, the realistic project-total ranges we see in 2026 across our service area break out roughly as follows:
- Shallow surficial-aquifer irrigation well (30 to 80 feet, no treatment, smaller pump): lower mid four-figure to mid four-figure project total.
- Standard residential Floridan Aquifer well (120 to 250 feet, full pump and tank, permit, water testing): high four-figure to low five-figure project total in most counties.
- Deep or complex Floridan Aquifer well (300+ feet, extended casing, karst conditions, larger pump): mid to upper five-figure project total.
- Well with included whole-house water treatment (iron and sulfur removal, softener, RO): add several thousand dollars depending on the contaminants and the household size.
These ranges are not promises. They are the bands our quotes have been landing in across recent projects. The only useful number is the written quote your contractor produces after a site visit and a review of WMD records for nearby wells.
Questions to Ask Any Contractor in 2026
- Are you Florida-licensed as a water well contractor? (Ask for the license number; it is on the state DEP roster.)
- Does your quote include the WMD permit fee and your labor to manage the permit?
- What casing material and length are you quoting, and why?
- What pump make, model, and horsepower are you installing?
- What pressure tank size and brand?
- Does the quote include bacteriological testing before the well goes into service?
- What is the workmanship warranty on the well, pump, and pressure tank separately?
If a contractor cannot answer those questions in writing, find one who can.
Floridan Aquifer Geology: Why Two Adjacent Lots Quote Differently
The Upper Floridan Aquifer is a regional limestone formation that underlies the entire peninsula, but its depth, thickness, and overlying confining layer vary across Central Florida in ways that directly drive drilling cost. In Marion County's Belleview and Ocala corridor, the productive limestone often sits within 80 to 120 feet of the surface under thin clay overburden, which keeps casing length short and drilling fast. Move 30 miles east into the karst pocket near Silver Springs and the same productive zone may be cavity-riddled, requiring extra grout pours through cavities to keep the casing seal intact. The grouting alone can add several hundred dollars on a single bore.
Alachua County around Gainesville sits over a thicker intermediate confining unit. The Floridan productive zone there is typically 200 to 320 feet down, and the contractor often has to drive PVC or steel casing through 120 to 180 feet of clayey overburden before reaching limestone. Both the longer casing run and the heavier drill rig time push cost upward relative to Marion. Polk County wells in the Lakeland and Winter Haven area land even deeper, with completions in the 300 to 400 foot range routine because the Lakeland Ridge sits on thicker overburden. Volusia County wells on the Atlantic Coastal Ridge fall in the middle: usually 180 to 300 feet with manageable casing length. Seminole County and east Orange County wells in the rolling sandhills are mostly 200 to 280 feet to a clean Floridan zone.
The point is not to memorize numbers. The point is that every quote that does not start with "let us pull the WMD nearby-well records for your specific parcel" is guessing. We pull those records before we quote.
What Quality Filters And Pumps Does Differently
We have been drilling and servicing wells across Marion, Alachua, Orange, Lake, Polk, and Volusia counties for 15+ years. We hold Florida Water Well Contractor License #7494. Every quote we produce comes after a site visit, a review of the WMD nearby-well database, and a discussion with the homeowner about expected use and water quality goals. We do not price wells over the phone. We do not subcontract the permit. We finish every well with a written maintenance plan and a bacteriological clearance result you can keep.
