Septic System Installation in Larimer County

In Larimer County, shallow, rocky, or clay-heavy soils are common, especially in the foothills and rural areas. These conditions may require engineered or advanced wastewater systems to meet regulations.
As septic system installers in Larimer County, we’re used to navigating these types of sites. We handle the full process—design, permitting, installation, and a customized grading plan—so you can have peace of mind with a system designed for your specific site.
Engineered Septic Systems in Larimer County
Site Evaluation & Soil Percolation Test
With a soil test, we measure your soil’s drainage capacity and determine what engineered solutions are required based on your lot’s size, slope, and soil type.
Leach Field Sizing & Layout
To work with tricky slopes, tight lots, and clay-heavy or shallow soils, we determine the size and placement of your leach field, including choosing the right type—whether it’s a pressure distribution system, raised bed, or an alternative drain field design.
Tank & Pump System Engineering
In the foothills, where elevation changes are common, engineered septic systems are often required. We engineer tanks with pumps or pressure dosing systems to push wastewater across sloped lots for efficient flow and prevention of backups across steep or rocky areas.
Grading Plan & Runoff Control
Heavy rainfall and snowmelt can pose significant risks to your septic system. We develop a custom grading plan for erosion control, diverting water away from your system and preventing erosion or saturation issues specific to your land.
Larimer County Permits Included
We handle all of Larimer County’s Onsite Wastewater Treatment System (OWTS) permitting requirements and approval processes for you. We submit all documentation, including soil tests, system designs, and erosion control plans, streamlining the approval process and allowing your septic system installation to proceed without delays.
