Advanced Septic Solutions for Fort Collins Homeowners

📋 Certified NAWT Property Transfer Inspections

Selling a property on a septic layout anywhere in the Fort Collins area requires a formal verification before the title can close. Larimer County mandates specific administrative checks on mechanical components to ensure raw sewage isn't threatening local surface waters or shallow water tables.

Our team provides official NAWT septic inspections in Fort Collins. We trace your lines, test pump alarms and float switches, evaluate structural tank concrete for gas corrosion, and deliver the compliant documentation your real estate transaction requires.


🚜 Engineering for Expansive Clays & Watershed Protection

The geology surrounding the Cache la Poudre River features dense pockets of expansive clay that expand heavily when wet, making natural gravity filtration difficult. Closer to Horsetooth, shallow bedrock and strict watershed protection rules make advanced system setups a necessity.

We specialize in excavating precise soil test pits for new septic system installations and PERC profiling. Our technicians build code-compliant Advanced Treatment Units (ATUs) or pressure-dosed sand filters designed to purify wastewater cleanly before it hits the soil, guaranteeing long-term property safety.


Fort Collins Septic FAQs

Does Larimer County require an inspection to sell a home on septic in Fort Collins?

Yes. Real estate transfers in Larimer County involving an active On-Site Wastewater Treatment System (OWTS) require an official operational evaluation performed by a certified NAWT inspector prior to title closing.

How do Horsetooth Reservoir watershed rules and Poudre River soils impact septic design in Fort Collins?

Properties located near Horsetooth Reservoir or the Cache la Poudre River basin must adhere to rigorous Larimer County watershed protection standards. These sensitive zones often require Advanced Treatment Units (ATUs) or pressure-dosed sand filters to ensure maximum pathogen reduction before wastewater enters shallow alluvial water tables.
