Septic Permits in Routt County: What Property Owners Need to Know

If your property is outside a sewer district, and most of rural Routt County is, your wastewater is handled by an on-site system. The county calls it an OWTS, an on-site wastewater treatment system. Most people call it a septic system. They are the same thing, and it is permitted work.

This guide is written for property owners rather than for contractors, and it explains the shape of the process. It deliberately does not quote fee amounts, and there is a reason for that further down.

When You Need a Permit

Generally, you need a county permit to install a new system, to replace an existing one, and to make significant repairs or alterations to one. Routine maintenance such as pumping is a different matter. If you are unsure which category your job falls into, the county is the right place to ask, and asking first is much cheaper than asking afterwards.

The Process, In Order

1. Site and soil evaluation

Before anything can be designed, somebody has to find out what the ground will do with water. That means a soil profile and, typically, percolation testing. This is the step that decides the type and size of system your property needs, and it is why two neighboring parcels can need very different systems at very different prices.

2. System design

The results drive a design. Straightforward sites on good soil may be designed conventionally. Sites with difficult soils, shallow depth to bedrock or groundwater, steep ground, small lot sizes or higher flows commonly require a design prepared by a professional engineer.

3. Permit application

The design goes to the county with the application. The county reviews it against its regulations and issues the permit before any work starts.

4. Installation by a registered installer

Routt County requires that the installation is carried out by an installer registered with the county, and holds that installer to the terms of the permit. David Stoltzfus is registered with Routt County. That registration is specific to Routt County, and does not extend to neighboring counties, which administer their own.

5. Inspection

The system is inspected before it is covered. This is not a formality and it is not something to work around. A system that gets backfilled before inspection can end up being uncovered again at your expense.

6. Final approval and records

Once approved, the system is on record with the county. That record matters later, particularly when the property is sold.

Why We Are Not Quoting You Fees

Permit fees, review fees, inspection fees and the thresholds that trigger an engineered design are all set by the county, and they are reviewed and changed. A specific dollar figure published on a contractor’s website is accurate for about a year, and then it quietly becomes a number that misleads people.

So the honest version is this: check the current figures with Routt County Environmental Health at co.routt.co.us, or ask us and we will tell you what applied on the last job we did. What we can tell you without any risk of being out of date is that the permit and design costs are a real line item and should be in your budget from the beginning, not discovered halfway through.

What This Costs Overall

The system itself is the larger number, and it moves with soil results, whether engineering is required, depth, distance from the house and haul distance. Anyone quoting a septic system price before the soil work has been done is guessing. We give a firm number once we know what the ground is.

Timing, Which Is the Part That Catches People

The excavation is days. The testing, design, permit and inspection around it are weeks, and they are sequential rather than parallel. At this elevation there is also a working season, so a permit that comes through in late October may still mean a spring install.

If you are building and your certificate of occupancy depends on the septic system, start this process much earlier than feels necessary. It is the single most common scheduling mistake we see.

Buying or Selling a Property

A septic inspection is standard on rural property transactions here, and a failed one arrives at the worst possible moment. If you are selling, find out what your system is going to do before a buyer does. If you are buying, ask for the county record and get the system looked at properly.
