About Well Drilling in Fort Myers

Water well drilling is the process of boring a hole into the earth to access underground aquifers that provide fresh water for drinking, irrigation, and household use. Approximately 43 million Americans rely on private wells as their primary water source. Residential wells typically range from 100 to 500 feet deep depending on the local geology and water table depth, though some areas require wells exceeding 1,000 feet. The drilling method depends on the geological conditions — rotary drilling is most common for deep wells through rock formations, while cable tool (percussion) drilling works well in unconsolidated materials like sand and gravel. After drilling, the well is cased with steel or PVC pipe to prevent contamination from surface water, and a submersible pump is installed at the appropriate depth to bring water to the surface. A pressure tank system in your home maintains consistent water pressure. The complete system includes the well itself, casing, pump, pressure tank, and connection piping. New wells require permits from state or local water authorities, and most states mandate a water quality test before the well can be used. Costs vary enormously by region and depth — from $6,000 in the Southeast to over $30,000 in areas with deep bedrock or difficult drilling conditions.

What Fort Myers Homeowners Should Know

Local Soil Conditions: Lee County soils are dominated by the Immokalee, Myakka, and Wabasso series — poorly drained Spodosols (flatwoods soils) with a diagnostic spodic horizon of dark, organic and aluminum-enriched soil 18–36 inches below the surface. This spodic horizon, formed under the historically wet flatwoods landscape, acts as a near-impermeable layer that perches water above it seasonally. Surface soils are fine sand with very rapid percolation (less than 6 minutes per inch), but the rapid percolation through the A horizon provides minimal treatment of effluent before it encounters the spodic layer or the water table. Coastal areas near Estero Bay and the Caloosahatchee River estuary have Durbin and Pompano series muck soils — organic, poorly drained, and entirely unsuitable for septic. Some inland Lee County areas have Arzell and Tavares series fine sands on slightly elevated ridges, which are the best available sites for conventional systems.

Water Table: Lee County's water table is extraordinarily shallow and seasonally variable — the defining constraint for every septic installation in Southwest Florida. During the wet season (June–September), the water table rises to within 12–18 inches of the surface across most of Lee County's flatwoods, and in low-lying areas it reaches the surface. During the dry season (November–April), it drops to 2–4 feet. Florida's 24-inch unsaturated soil requirement for drainfield bottoms is measured against the seasonal high water table, meaning most Lee County lots need engineered mound or drip systems that elevate the treatment zone above the seasonal high. The Caloosahatchee River floodplain and the extensive tidal marsh systems of Estero Bay further complicate siting in coastal zones.

Climate Impact: Fort Myers has a tropical savanna climate with a pronounced wet season from June through September delivering 80% of the annual 55 inches of rainfall. The dry season from November through April can see weeks without measurable rain, causing the water table to drop but not enough to allow year-round conventional drainfield operation at FDEP's 24-inch unsaturated soil requirement. The 2004 and 2005 hurricane seasons brought back-to-back direct hits from Charley, Jeanne, and Wilma within 14 months, flooding thousands of Lee County properties including many septic systems. Hurricane Ian in September 2022 caused catastrophic flooding across Lee County — Fort Myers Beach was essentially destroyed — and the resulting septic system damage survey identified hundreds of failed and compromised systems requiring replacement.

Signs You Need Well Drilling

  • Building a new home without access to municipal water supply
  • Existing well has gone dry or produces insufficient water
  • Water quality has deteriorated beyond what treatment can fix
  • Adding irrigation needs that exceed existing well capacity
  • Existing well is contaminated and cannot be rehabilitated

The Well Drilling Process

  1. 1 Site assessment and hydrogeological survey to identify the best drilling location
  2. 2 Obtain required drilling permits from state or local water authority
  3. 3 Mobilize drilling rig and begin boring through soil and rock layers
  4. 4 Install well casing and screen at the appropriate aquifer depth
  5. 5 Develop the well by pumping to clear drilling debris and maximize flow
  6. 6 Install submersible pump, pressure tank, and connection piping
  7. 7 Conduct water quality testing and obtain certificate of completion

Frequently Asked Questions — Fort Myers

Why does Fort Myers have so many mound septic systems instead of conventional in-ground systems?
Florida requires 24 inches of unsaturated soil below the drainfield bottom at the seasonal high water table. Lee County's flatwoods soils have seasonal high water tables at 12–24 inches below grade across most of the county, meaning conventional trenches at the standard 12–18 inch installation depth would violate this requirement. Mound systems use imported clean fill to raise the drainfield above grade, creating the required 24-inch unsaturated zone above the seasonal high water table. The raised mound configuration is visible in many Lee County yards as a slight rise in the lawn, typically 12–24 inches above surrounding grade and 20–40 feet across.
How did Hurricane Ian in 2022 affect septic systems in the Fort Myers area?
Hurricane Ian made landfall near Fort Myers Beach in September 2022 as a Category 4 hurricane with a storm surge of 15–18 feet in some areas. The catastrophic surge flooding inundated thousands of OSTDS across Lee County, including the barrier islands, Fort Myers Beach, Cape Coral's canal districts, and inland areas along the Caloosahatchee River floodway. Surge water flooded septic tanks through risers and vents, displaced mound systems, and in some cases completely destroyed drainfield distribution systems. The Lee County DOH conducted post-storm surveys and issued guidance requiring all flooded OSTDS to be pumped and inspected by a licensed contractor before residential reoccupancy. Many systems required complete replacement because the imported fill in mound systems had been hydraulically displaced.
Is Fort Myers at risk of stricter septic regulations due to algae blooms in the Caloosahatchee?
Yes. The Caloosahatchee River estuary has experienced recurring severe blue-green algae blooms in recent years, driven by elevated phosphorus and nitrogen from multiple sources including agricultural runoff, Lake Okeechobee discharges, and onsite sewage systems. FDEP and the South Florida Water Management District are developing a Basin Management Action Plan (BMAP) for the Caloosahatchee watershed. If and when a BMAP is finalized for this watershed, Lee County could be added to the list of 16 priority counties where Enhanced Nutrient Reduction (ENR) systems are required for new installations and major repairs. ENR systems cost $3,000–$8,000 more than conventional systems but reduce nitrogen output by 50–75%.
What are the setback requirements for septic systems near Lee County canals and waterways?
Florida FAC 64E-6 requires a minimum 75-foot setback from the seasonal high water line of any surface water, including canals, drainage ditches, ponds, and tidal waterways. Cape Coral and other canal-front communities in Lee County have a vast network of man-made canals, and many lots are too narrow to site a compliant drainfield at 75 feet from the canal while also maintaining required setbacks from the house. Properties in these situations may require a variance, a different system type such as an aerobic unit with subsurface drip, or connection to available municipal sewer. Lee County is actively expanding central sewer infrastructure in canal-front communities partly to address this setback challenge.
How often should septic tanks be pumped in Lee County's climate?
Florida's warm subtropical climate accelerates biological decomposition in septic tanks year-round, unlike northern states where cold winters slow microbial activity. The Lee County DOH recommends pumping every 3–5 years for a typical three-bedroom household. The high water table common throughout Lee County means tanks are regularly subject to groundwater pressure on their exterior walls, which can accelerate joint separation and infiltration of groundwater into the tank, diluting the treatment process and increasing effluent volume. Any tank that shows signs of groundwater infiltration (unusually rapid refill after pumping) should be inspected for structural integrity.
