About Septic Inspection in Cheyenne

A septic inspection is a thorough evaluation of your entire septic system — tank, distribution box, drain field, and all connecting pipes. There are two types: a visual inspection (basic check of flow and obvious problems) and a full inspection (pumping the tank, measuring sludge layers, checking baffles, probing the drain field, and testing mechanical components). Full inspections are typically required when selling a home, and many mortgage lenders will not approve financing without one. During a real estate inspection, the technician will locate all system components, verify the tank size matches the home's bedroom count, check for evidence of past failures or unpermitted repairs, and provide a written report with photos. Even outside of real estate transactions, periodic inspections (every 1-3 years) can catch small problems before they become expensive emergencies. The inspection report becomes a valuable record of your system's condition and maintenance history. Most states require inspectors to hold specific licenses or certifications, so always verify credentials before hiring.

What Cheyenne Homeowners Should Know

Local Soil Conditions: Featherlegs loam and Altvan loam on the High Plains surface — Aridic Argiustolls and Typic Haplustalfs with moderate percolation; Nunn clay loam in lower positions with slower drainage; Larim gravelly sandy loam on upland ridges with excellent percolation; Bentonite-bearing Pierre Shale formations create localized expansive clay hazards

Water Table: 20 to 50 feet in most areas; deeper in the High Plains; shallower near Crow Creek and Dry Creek drainages

Climate Impact: Semi-arid steppe (BSk) at 6,062 feet elevation. One of the windiest cities in the U.S., with average wind speeds of 12-14 mph. Cold winters with frequent blizzards; mild summers. Annual precipitation 15 inches. High elevation accelerates UV degradation of exposed plastic components.

Signs You Need Septic Inspection

  • Buying or selling a home with a septic system
  • Refinancing a mortgage on a septic-served property
  • Obtaining a building permit for an addition or renovation
  • System has not been inspected in more than 3 years
  • Concerns about system age, condition, or past issues

The Septic Inspection Process

  1. 1 Locate all system components using available records or electronic locating equipment
  2. 2 Pump the tank and measure sludge and scum layer depths
  3. 3 Inspect tank interior, baffles, tees, inlet and outlet pipes
  4. 4 Check the distribution box for level flow to all drain field lines
  5. 5 Probe the drain field for signs of saturation or failure
  6. 6 Prepare a detailed written report with findings, photos, and recommendations

Frequently Asked Questions — Cheyenne

What parts of the Cheyenne area are on septic systems?
Cheyenne city limits are largely served by municipal sewer. Rural residential areas throughout Laramie County — including ranch lots along I-25, Fox Farm, Carpenter, and Burns communities — are on private septic systems. Many acreage developments within 10 miles of the city also use septic. Contact Laramie County Planning to verify sewer availability for any specific address.
What is Bentonite and why does it matter for septic systems in Cheyenne?
Bentonite is a highly expansive clay mineral derived from weathered volcanic ash, found in Wyoming's Pierre Shale formations. When wet, Bentonite swells dramatically — sometimes to 15 times its dry volume. This creates structural damage to rigid septic tanks and pipe connections, and essentially zero percolation for leach fields. If a soil evaluation finds Bentonite-bearing materials, an engineered alternative system (mound, drip irrigation) must be designed to avoid the restrictive zone.
How does Cheyenne's wind affect septic systems?
Cheyenne's persistent high winds (averaging 12-14 mph) benefit evapotranspiration-based systems by increasing surface moisture loss, but they also accelerate UV degradation of exposed plastic components like risers and distribution boxes. All above-grade components should be UV-resistant. Wind-driven soil erosion can also expose leach field piping if proper revegetation is not established after installation.
Are there septic restrictions near Cheyenne's Granite Reservoir?
Granite Reservoir is a primary drinking water source for Cheyenne. WDEQ and Laramie County require enhanced setbacks and advanced treatment for any septic systems within the reservoir's contributing watershed. New systems are rarely approved in this area, and existing systems near the reservoir face increasing pressure to upgrade or connect to an extended sewer line.
What does a WDEQ Chapter 25 site evaluation involve?
A Wyoming Chapter 25 site evaluation includes a detailed soil profile description to a minimum depth of 5 feet using a backhoe pit, a percolation test in the design leach field area, measurement of seasonal high water table, and documentation of any restrictive layers. The evaluation must be performed by a WDEQ Registered Site Evaluator or Professional Engineer. Results determine the system type, size, and setback requirements.
