Septic System Installation in Boulder County

In Boulder County, shallow, rocky, or clay-heavy soils are common, and many properties have sloped or tight lots that limit where a system can be placed.

Because of these conditions, an engineered system system is often required: including pumps to move wastewater across sloped areas, advanced treatment methods, pressure-distribution leach fields, and a customized grading plan to control runoff and erosion. As septic system engineers and installers in Boulder, we’re used to navigating these types of sites. We handle the full process—design, permitting, and installation—so you can have peace of mind with a system designed for your specific site.

Engineered Septic Systems in Boulder 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 Boulder’s 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 Boulder’s 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.

Boulder County Permits Included

We handle all of Boulder 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.
