About Well Drilling in Allentown

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 Allentown Homeowners Should Know

Local Soil Conditions: Lehigh County sits in the Great Appalachian Valley (Lehigh Valley), a broad limestone belt between the Blue Ridge/South Mountain to the south and the Kittatinny Ridge to the north. The dominant septic-relevant soil in the Lehigh Valley lowlands is the Duffield-Hagerstown-Murrill association — deep, well-drained silt loams developed from weathered limestone with percolation rates of 30 to 60 minutes per inch in the subsoil. Karst features — sinkholes, solution conduits, and pinnacled bedrock — interrupt the otherwise favorable soil profile and create unpredictable vertical permeability. The Blue Mountain foothills north of Allentown have Laidig and Dekalb channery soils with moderate to rapid percolation but shallower effective depth.

Water Table: The Lehigh Valley limestone aquifer is generally 20 to 50 feet deep on upland terrain, but karst dissolution features create direct surface-to-aquifer connections at sinkholes and losing stream reaches. The Cedar Creek and Monocacy Creek valleys in Lehigh County have seasonal water tables within 18 to 36 inches. The Lehigh River floodplain has water tables of 2 to 4 feet. Allentown's primary water supply comes from the Lehigh River and Little Lehigh Creek, making groundwater protection in the karst Lehigh Valley a high-priority public health concern.

Climate Impact: Allentown has a humid continental climate with warm summers (July average 84°F) and cold winters (January average 18°F low). The Lehigh Valley's ridge-and-valley topography funnels cold air and creates colder valley temperatures than surrounding areas. Annual precipitation is 46 inches, fairly evenly distributed, with occasional large snowstorms from nor'easters. Spring snowmelt and rain saturates the valley soils and creates peak stress on drainfields, particularly in the limestone lowlands where drainage can be impeded by karst features.

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 — Allentown

How does Lehigh Valley karst affect my septic system?
Lehigh Valley karst means the limestone beneath your property has been dissolved into sinkholes, fractures, and conduits over millions of years. If your drainfield is near a sinkhole or karst feature, effluent can bypass soil treatment and reach the limestone aquifer within hours — completely defeating the purpose of your septic system. This is why the Lehigh County Health Bureau requires karst feature surveys before issuing permits in high-risk areas.
How often should I pump my septic tank in the Allentown area?
Every 3 to 5 years is standard for a typical household in Lehigh County. Given the karst geology, a failing system here can cause rapid, widespread groundwater contamination — so prompt maintenance is especially important. If your property is near a sinkhole or mapped karst feature, 3-year pumping intervals are advisable, and annual drainfield inspections are prudent.
What is the cost of a new septic system near Allentown?
Conventional systems in the Lehigh Valley limestone soils typically run $6,000 to $10,000. Sites requiring mound systems for high water table or slow-perc soils run $10,000 to $16,000. If extensive karst mapping reveals that a portion of your lot is unsuitable and forces a constrained drainfield design, engineered solutions can reach $18,000 to $22,000. Soil evaluations ($400-$700) before purchase are essential in karst terrain.
Can sinkholes appear under my Lehigh Valley drainfield?
Yes — new sinkholes can open in Lehigh Valley karst terrain, including beneath existing drainfields. The Lehigh County Health Bureau recommends monitoring the ground surface over your drainfield area for any new depressions or settling. If a sinkhole opens near your drainfield, stop using the system immediately and contact the Health Bureau and a licensed system professional. A new sinkhole can instantly compromise an otherwise functioning septic system.
Does Allentown's water supply affect septic regulations in the area?
Yes. Allentown draws water from the Little Lehigh Creek and its watershed, and the Lehigh County Health Bureau applies enhanced setback and review requirements for septic systems in the Little Lehigh and Cedar Creek watersheds. Properties within 1,000 feet of these streams receive additional scrutiny during permit review. The Bureau and PA DEP jointly monitor nitrate levels in Little Lehigh Creek, and outlying township septic systems are considered a contributing source.
