About Septic System Installation in Scranton

Septic system installation is a major construction project that involves designing and building an underground wastewater treatment system customized for your property. The process begins with a percolation (perc) test, where a soil scientist or engineer evaluates how quickly your soil absorbs water — this determines which system type is appropriate. Conventional gravity systems work well in areas with good drainage and adequate soil depth, while properties with high water tables, clay soils, or limited space may require engineered alternatives like mound systems, aerobic treatment units (ATUs), or drip distribution systems. Installation involves excavating for the tank, laying distribution pipes, constructing the drain field, and connecting the household plumbing. The entire process typically requires permits from your local health department, inspections at multiple stages, and a licensed installer. Costs vary dramatically by region, soil conditions, and system complexity — from $3,500 for a basic conventional system to over $20,000 for an engineered aerobic unit. Proper installation by a licensed professional is critical: a poorly installed system can contaminate groundwater, fail prematurely, and create expensive legal liability.

What Scranton Homeowners Should Know

Local Soil Conditions: Scranton-area soils reflect its position in the Wyoming Valley anthracite coal region and the Pocono Plateau transition zone. Dominant series include Leck Kill channery silt loam, Alvira silt loam, and Hazleton channery sandy loam — Inceptisols and Spodosols formed in colluvium and residuum derived from gray and red Devonian-Mississippian shales, sandstones, and conglomerates. The Leck Kill series is a moderately deep Typic Dystrudept over fractured shale with moderate permeability in surface horizons and rapid lateral flow along shale fractures in the subsoil. The Alvira series — found on footslopes and toeslopes — has a fragipan horizon (Bx) at 22-34 inches with very slow permeability and a seasonal high water table above the fragipan. Mine spoil and disturbed land soils from the anthracite coal mining legacy are common across the urban landscape.

Water Table: Upland shale and sandstone ridge soils in Lackawanna County have variable water tables depending on topographic position — ridgeline soils are typically excessively well-drained, while footslope Alvira soils have seasonal water tables at 12-24 inches above the fragipan. Valley bottom and stream terrace soils in the Lackawanna River corridor have high water tables at 18-36 inches. Former mine subsidence areas may have unpredictable drainage patterns. Lackawanna County SEOs require careful seasonal high water table determination given the fragipan constraints.

Climate Impact: Scranton has a humid continental climate at 1,000-foot elevation in the Ridge-and-Valley province. Winters are cold and snowy, with significant lake-effect enhancement from the Great Lakes reaching the region as modified air masses. Average annual snowfall is 43 inches. Summers are warm and humid. Annual precipitation is 37 inches with relatively even distribution. The region's geology produces many small streams and springs that respond quickly to rainfall, creating seasonal saturation events in footslope soil positions common in OSSF drainfields.

Signs You Need Septic System Installation

  • Building a new home without access to municipal sewer
  • Existing system has failed beyond repair
  • Adding significant square footage or bedrooms to your home
  • Converting a property from dry well or cesspool to modern septic
  • Local regulations require system upgrade or replacement

The Septic System Installation Process

  1. 1 Site evaluation and percolation test by a licensed soil scientist
  2. 2 System design by a licensed engineer based on soil and household size
  3. 3 Obtain permits from the county or state health department
  4. 4 Excavate the tank pit, distribution box area, and drain field trenches
  5. 5 Set the tank, connect inlet/outlet pipes, and install the distribution system
  6. 6 Backfill, grade the site, and restore landscaping
  7. 7 Schedule required inspections and obtain final approval

Frequently Asked Questions — Scranton

How does coal mining history affect septic systems in Scranton?
Lackawanna County's anthracite coal mining history left a legacy of underground mine workings, subsided land, and disturbed mine spoil across large portions of the urban and suburban landscape. Mine subsidence can cause ground movement that cracks septic tanks, damages distribution boxes, and shifts drainfield laterals. Mine spoil (waste rock from mining operations) used as fill material may have poor or unpredictable drainage characteristics. Properties in known subsidence areas or on deep fill may require special engineering review before OSSF installation.
How much does septic pumping cost in Scranton?
Septic tank pumping in the Scranton and Lackawanna County area ranges from $250 to $475 for a standard 1,000-gallon residential tank. Northeastern Pennsylvania service providers typically charge $275-$400. Rural township properties may see slightly higher prices for travel. Pumping every 3-5 years is standard under Act 537 guidance.
Does Scranton have municipal sewer or do homes use septic?
The City of Scranton and most boroughs including Dunmore, Taylor, Dickson City, Blakely, Jessup, and Old Forge are served by municipal sewer. Septic systems are primarily found in the rural townships of Lackawanna County — Jefferson, Madison, Covington, Clifton, Scott, and Benton townships — and in communities throughout the broader northeastern Pennsylvania region. If you are purchasing in a rural Lackawanna County township, you are likely on septic.
What is Act 537 and how does it affect my septic permit in Lackawanna County?
Pennsylvania's Act 537, the Sewage Facilities Act, requires all municipalities to maintain an official Sewage Facilities Plan that maps existing and future sewage service. Before any new OSSF is installed, the municipality must issue a planning module approval confirming that individual sewage is appropriate for that location. This adds a step to the permit process — your SEO will guide you through both the planning module and the individual permit requirements. Act 537 also empowers municipalities to require OSSF remediation when failing systems create public health hazards.
My Scranton-area property has a footslope location — what soil problems should I expect?
Footslope and toeslope positions in Lackawanna County commonly contain Alvira silt loam — a soil with a fragipan subsoil horizon that creates a perched seasonal water table. During wet seasons (March-May and October-November), water percolating down from upslope positions accumulates above the fragipan and can raise the apparent water table to within 12-18 inches of the surface. This is called a seasonally perched condition, and Pennsylvania requires OSSF drainfield bottoms to maintain 24-inch separation from this perched water table. Your SEO will determine the seasonal high water table during the site evaluation.
