Service Area · I-70 mountain corridor
Senior-led septic, excavation, driveways, water storage, and custom building across Clear Creek County — I-70 mountain corridor at 7,500–10,000 ft — with the hard mountain site work handled in-house.
We do more than dig a hole and drop in a tank.
Tri-Lakes Contracting is a licensed septic installer, excavation contractor, and custom home builder working throughout Clear Creek County. Site work and septic permitting are the critical first steps before you can even break ground on a build — and they’re exactly what we handle, start to finish.
Because we hold the septic, driveway, and building sides in-house, we bundle them into one path instead of stitching together three separate contractors: soil testing and engineered design, excavation and grading, the septic system, water storage, and the home itself — one crew, one point of contact, on your schedule.
We know Clear Creek County terrain inside and out — tight canyon parcels, mine-disturbed ground, and very short building seasons. Whether your property is in Idaho Springs, Georgetown, Empire and Lawson, we deliver site work built for I-70 mountain corridor conditions and permitted under Clear Creek County Public & Environmental Health and Colorado’s Regulation 43.
What we handle in Clear Creek County
We excavate profile test pits, work with licensed engineers on the soils report and site plan, and lay out the drain field, tank, and setbacks — the design your Clear Creek County Public & Environmental Health permit stands on.
Full onsite wastewater systems — conventional, pressure-dosed, and advanced-treatment — installed for I-70 mountain corridor ground and Clear Creek County Public & Environmental Health review.
Access, building pad, utilities, and all-weather driveways cut for Clear Creek County — tight canyon parcels, mine-disturbed ground, and very short building seasons.
Buried cisterns and fire-suppression storage for lots without a reliable well, or where the county requires stored water on site.
From a build-ready design or your own plans, we take a raw Clear Creek County lot through to a finished, permitted home.
Before you buy or build, a clear read on what the lot can support — soil, slope, setbacks, water, and the permit path.

What we don’t do
We don’t design or stamp septic systems ourselves — that work is always completed by a licensed engineer. But we work closely with our engineering partners so you receive a complete, permit-ready package that passes Clear Creek County Public & Environmental Health review the first time, without the back-and-forth that stalls a Clear Creek County build.

Where we work in Clear Creek County
We serve Idaho Springs, Georgetown, Empire and Lawson and the surrounding I-70 mountain corridor high country, out from Georgetown. At 7,500–10,000 ft, Clear Creek County brings tight canyon parcels, mine-disturbed ground, and very short building seasons — conditions our crews work in every week, not once a season.
Clear Creek County — questions
Yes. We excavate the soil test pits, coordinate the engineered design with a licensed engineer, and hand you a permit-ready package for Clear Creek County Public & Environmental Health under Colorado Regulation 43. On I-70 mountain corridor ground — tight canyon parcels, mine-disturbed ground, and very short building seasons — that soil evaluation is what the whole system is designed from.
That’s our model. Because we hold the septic, excavation, and building sides in-house, we sequence them into one path — soil test, design, driveway, septic, water, and the home — instead of you chasing three contractors across Clear Creek County.
