What Our Customers Say About Blayne & The Team at Dirty Deeds
How a Septic Installation Works in Northern Arizona
Septic installations in Northern Arizona are not the same as other parts of the country.
Our rocky terrain, high elevation, and varied soil conditions in Coconino County require a contractor who knows what they are doing before the first shovel hits the ground.
At Dirty Deeds Tractor and Services, we handle the entire process from the first site visit through your final county inspection.
Step 1: Site Evaluation and Perc Testing
We visit your property and assess the soil, slope, and available space for your system. A percolation test measures how fast your soil absorbs water, which determines what type of system you need and where the leach field gets placed.
Step 2: Permit Filing with Coconino County
We visit your property and assess the soil, slope, and available space for your system. A percolation test measures how fast your soil absorbs water, which determines what type of system you need and where the leach field gets placed.
Step 3: Excavation, Tank Placement and Leach Field
Our equipment digs the tank pit and leach field trenches, places the tank, runs all connections, and backfills the site. We work carefully to minimize disruption to your property and surrounding land.
Step 4: Final Inspection and Hookup
Once the system is in place, we schedule and pass final inspection with the county. Your system is then connected and ready to use. We make sure everything is documented and meets all local code requirements before we leave.
What Affects the Cost of Septic
Installation in Northern Arizona
Every property is different. Before we can give you an accurate number, we need to see the site. Here are the main factors that affect what your septic installation will cost:
Property Size and Soil Type
Larger properties and rocky or clay-heavy soil can require additional excavation time and equipment. Our perc test results tell us exactly what your soil can handle.
Distance and Site Access
Properties further from paved roads or with steep terrain may require additional equipment or setup time to safely access the work area.
Tank Size Required
Tank size is based on the number of bedrooms in your home or cabin. A one-bedroom cabin needs a smaller system than a four-bedroom house. We size the right tank for your actual usage.
Leach Field Length
Perc test results directly determine how long your leach field needs to be. Slower-draining soil requires a longer field to properly distribute effluent.
Coconino County Permit Fees
Permit costs are set by the county and vary based on the scope of the project. We walk you through what permits are required and include them in your estimate.
Existing Site Conditions
If your property has trees, rocks, or existing structures near the planned installation area, we account for that during our site visit and estimate.
