About Well Drilling in Midland

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 Midland Homeowners Should Know

Local Soil Conditions: Midland County soils are dominated by the Midland clay series, Olton clay loam, and Amarillo fine sandy loam — Mollisols and Aridisols of the High Plains Permian Basin. The Midland clay series is a calcareous Vertisol with 50-70% smectite clay that exhibits strong shrink-swell behavior. Petrocalcic (caliche) horizons — dense, cemented calcium carbonate layers — occur at depths of 12 to 48 inches across much of the county, creating a near-impermeable barrier for drain field effluent. Sandy loam surface horizons in some areas offer initial permeability but the caliche layer beneath limits total system capacity.

Water Table: Deep water table — typically greater than 100 feet below land surface throughout Midland County. The Permian Basin's arid climate means no seasonal water table shallowing. The constraint is the caliche layer, not groundwater depth.

Climate Impact: Midland has a semi-arid climate with hot, dry summers and cold winters. Annual precipitation averages only 14 inches, making Midland one of the driest cities in Texas with a septic-significant population. The combination of low rainfall, high evapotranspiration, and deep water table creates a very different septic environment from the rest of Texas — drain field saturation from precipitation is rarely a concern, but caliche layers and clay shrink-swell remain primary design challenges.

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 — Midland

What is caliche and how does it affect septic systems in Midland?
Caliche is a common term for petrocalcic horizon — a calcium carbonate-cemented layer in arid and semi-arid soils of West Texas. In Midland County, caliche layers occur at depths of 12 to 48 inches and can be as hard as concrete. For septic systems, caliche prevents drain field trench excavation and blocks effluent infiltration below the layer. When caliche is shallow, conventional systems are not possible and engineers must design alternative approaches such as shallow low-pressure pipe systems in imported sandy soil, or drip irrigation systems operating at very low application rates on the clay surface above the caliche.
How much does septic pumping cost in Midland?
Septic tank pumping in Midland County ranges from $225 to $425. The semi-arid climate means septic bacteria are somewhat less active than in humid climates, but standard 3-5 year pumping intervals still apply. The Permian Basin's oil and gas economy means service pricing can vary significantly based on the local labor market — during oil booms, labor costs rise and septic service prices may increase accordingly.
Does the deep water table in Midland mean I don't need to worry about my septic system affecting groundwater?
The deep water table (100+ feet) does significantly reduce the near-term risk of septic effluent reaching drinking water aquifers compared to shallow water table areas. However, in an arid environment where groundwater recharge is limited, any contamination that does reach the aquifer is long-lasting. TCEQ still requires proper system design, setbacks from wells, and ongoing maintenance for all Midland County OSSF systems. The caliche layer, while blocking effluent movement downward, can also cause it to move laterally — which is why proper site evaluation is still essential.
How does Midland's oil boom population growth affect the septic permit market?
Permian Basin boom cycles drive rapid housing construction in rural Midland County, often outpacing municipal sewer extension. During peak oil activity periods, Midland County Environmental Health sees sharp increases in OSSF permit applications for new rural residential properties housing energy sector workers. Boom periods can also strain the contractor workforce, leading to longer wait times and higher installation costs. Property buyers in new rural subdivisions should confirm OSSF permit status before closing.
Can I use my Midland septic system for a guesthouse or secondary dwelling on my acreage property?
Not without a separate permit evaluation. TCEQ and Midland County require each dwelling unit to have its own properly sized and permitted OSSF, or for multiple units to be served by a system sized for the total combined bedroom count. Adding a guesthouse or ADU served by an existing septic system requires a permit amendment and possibly system expansion. The site's caliche depth and available soil volume above it will determine whether expansion is feasible.
