Outside the sewer service areas run by towns and districts, many Clear Creek County homes are not connected to a public sewer. They use an onsite wastewater treatment system, often just called a septic system.
A septic system treats household wastewater on the property, in the ground. When it works, you barely think about it. When it fails, it is expensive and can affect health and nearby water. That is why these systems are regulated, from how they are designed to how they are inspected. Clear Creek County administers its onsite wastewater rules locally, under the framework set by the state health department.
For a buyer, the key idea is simple: a septic system is part of the home you are buying, and it needs to be checked like any other major system. Clear Creek County ties an approval step to the sale of a home with an existing system, so the system gets reviewed before closing. Steep ground, rocky soils, and snow can all affect how a system is designed and how well it works here.
None of this is a reason to avoid a septic home. It is a reason to ask early what serves the property and what condition it is in.
