Turnkey excavation, certified soil profiling, and engineered system layouts built strictly to Colorado environmental codes for new residential builds.
When breaking ground on a new residential build, your On-Site Wastewater Treatment System (OWTS) is one of your property's most critical investments. At AB Septic, we manage the entire lifecycle of your installation from initial profile holes to final county health approval.
We coordinate directly with local environmental engineers and public health departments across Weld, Larimer, Boulder, Adams, Jefferson, and Arapahoe Counties to keep your build on schedule without regulatory delays. If replacing an existing failed system, explore our septic replacement services or drain field installation options.
Before an engineer designs a septic layout, excavating strategic soil test pits is a mandatory first step. These open excavations allow inspectors to examine underlying geology, calculate soil percolation limits, and establish seasonal high groundwater tables.
We provide precise excavation data to engineers to design gravity-fed or advanced treatment systems tailored to your home footprint and water load. We also provide NAWT use-permit inspections and rapid emergency septic repairs.

A percolation (PERC) test measures how quickly water drains through your soil. Colorado counties require this to properly size and engineer your leach field to prevent future hydraulic failure and groundwater contamination.
Once county permits and engineering designs are approved, the physical excavation and installation process typically takes 3 to 5 days, depending on weather and bedrock conditions.
Colorado health departments require new On-Site Wastewater Treatment Systems (OWTS) to be installed by state-licensed professionals to ensure environmental compliance and pass mandatory final health inspections.
Our team executes new OWTS engineering and site excavation projects across the Front Range:
We restore the site with clean final grading, leaving residential yards level and undisturbed.
