📞 Call (303) 632-0124
Whether you're building on a beautiful lot south of C-470 or replacing a system that's reached the end of its life, septic system installation is a major investment that has to be done right. Littleton Septic Pros designs and installs complete septic systems — tank, distribution, and drain field — engineered for your property's soil, sized for your household, and permitted through the county.
Installation starts long before excavation. We evaluate your site: soil percolation testing, setback measurements from wells, property lines, and waterways, and system sizing based on bedrooms and expected water use. Colorado counties are strict about septic design — and that's good, because a properly designed system lasts 30+ years while a shortcut system fails in ten.
We handle the entire process: design, permits, excavation, installation, inspections, and final grading. You get one accountable contractor, a firm price agreed before work starts, and a system backed by our workmanship warranty. When the county inspector signs off, you'll have documentation proving your system meets every requirement.
