Septic services across the Front Range
Every page below explains one piece of Front Range septic work in plain terms, with the county rules that apply in Jefferson, Larimer, and Boulder counties, then offers a free quote on that work.
One sale, three county documents
Most septic work on the Front Range traces back to a single trigger: Jefferson, Larimer, and Boulder counties each require a document before a home on an on-site wastewater system can sell, and that document rests on an inspection. The transfer inspection page covers each program in depth, and the Front Range septic transfer guide walks the whole sale timeline. The short version:
| County | Document | Issued by | Valid for | Newer-system exception |
|---|---|---|---|---|
| Jefferson | Use permit | Jefferson County Public Health | Until closing or six months, whichever comes first | Applies to a covered transaction unless the system was approved less than one year before closing (cut from five years on June 15, 2026) |
| Larimer | Acceptance document | Larimer County Department of Health and Environment | Until the closing date or 12 months, whichever comes first | Excepted when final approval came less than three years before the request |
| Boulder | Property Transfer Certificate | Boulder County Public Health | One year | Exempt when the entire system received final approval less than five years before closing |

Where these rules apply
The transfer trigger fires in the on-septic rings and mountain subdivisions, not the sewered metro cores. Each city page names the county office involved and carries the local specifics:

What it costs, and what happens after you send it
- What does septic work cost on the Front Range?
- It depends which job you need, and the three are not close. A new system or a full replacement is the five-figure one: Tri-Lakes Contracting (contractor-published) lists conventional systems at $10,000 to $20,000 and pressure distribution at $15,000 to $25,000, with engineered and advanced-treatment systems sit above those ranges, putting most Colorado projects at $10,000 to $50,000 or more. A transfer inspection is a different appointment at a different scale, published from $475 per system, with more for travel time or difficult access (Johnston Sanitation, contractor-published, Loveland). Routine pumping runs $250 to $895 by tank size in the Boulder area, with a Fort Collins average of $388 to $509, both aggregator estimates rather than contractor quotes. County permit fees are separate and each county publishes its own schedule. Soil, lot access and county requirements decide where any real quote lands.
- How fast will someone get back to me?
- Your request goes to an independent local septic contractor, usually within about an hour during the day. That contractor then contacts you to look at the system and price the work on their own schedule.
- What work is covered?
- Septic installation and replacement, septic repair, transfer and point-of-sale inspections, routine inspections, and pumping. See every service.
Only a contractor standing at your tank and soil treatment area can price your actual system.
