A Jeffco septic use permit does not approve the well

Buy a home up in the Jefferson County foothills and you inherit two systems that quietly run the place: the septic field out back and the well that brings your water. They tend to come up in the same breath, which makes it easy to assume one inspection covers both. It does not.

A septic use permit looks only at the onsite wastewater treatment system. The inspection stops there. It never examines the well and never vouches for how much water it produces or whether that water is safe to drink. The county’s own guidance is to have a private well checked for production, capacity, and quality, precisely because the permit leaves all of that untouched.

This is the gap that bites at closing. A seller can hand over a clean septic use permit, which genuinely matters, and a buyer can read it as a thumbs-up on the whole water picture. It says nothing about whether the well runs dry in late summer or whether the water needs treatment before anyone drinks it.

When a property leans on both an onsite wastewater system and a private well, the steady approach is to run them as two separate checks. Confirm the septic permit and use permit through Public Health, then arrange a well test and evaluation on its own. Two systems, two answers, and only one of them is in that permit.
