Septic & OWTS · Chaffee County
Septic system installation in Chaffee County, Colorado
Tri-Lakes designs, permits, and installs onsite wastewater systems throughout Chaffee County — from Salida to Nathrop. We build for valley alluvium framed by the Collegiate Peaks, with rocky bench ground, and we handle the Chaffee County Environmental Health permit and inspections start to finish.
Chaffee County sits in the Upper Arkansas Valley at roughly 7,000–9,000 ft — ground that decides how a septic system has to be built.
Onsite wastewater on Chaffee County lots means designing around valley alluvium framed by the Collegiate Peaks, with rocky bench ground. Those conditions rule out a one-size drainfield: the soil evaluation drives whether your lot takes a conventional gravity system, a pressure-dosed field, or an engineered treatment unit. We've built all three across the Upper Arkansas Valley.
Every install is permitted through Chaffee County Environmental Health under Colorado's Regulation 43. We prepare the stamped design, submit the OWTS permit, coordinate the county's inspections, and do the excavation in-house — so the same crew that reads your soil is the one setting your tank.

How your Chaffee County project works, start to finish
Site Feasibility Report
We start at your lot. On a site visit we check property setbacks, read the slope, make a hands-on visual assessment of the soil, and cross-reference county and health-department code for anything that could constrain a system. You get a written feasibility report and a real plan for the site — typically within three business days.
Testing Proposal
With the feasibility done, we quote the next step — the soil profile testing — so you know the cost before going any further.
Soil Profile Pit Test
Once you move forward, we come back out and dig two soil profile pits to read the actual soil horizons on your lot. That's the hard data the design depends on — no guesswork, no assumptions.
Engineered System Design
We hand the soil data to a licensed engineer, who designs and stamps the septic system plans your county requires.
System Proposal
With stamped plans in hand, we price the materials and permitting off the design and give you a firm quote on the actual system.
Installation
Once the system is approved and paid, our crew installs it — tank, drainfield or treatment unit, and lines. The same crew that read your soil is the one setting your system.
Inspection & Final
We schedule the county's final inspection, backfill, restore the site, and hand you a system documented for the life of the property.
