If you’re buying in an unincorporated part of Colorado, there’s a good chance your future home gets water from private wells. Your home inspection will check basic water pressure and flow at fixtures, but it won’t test your water quality or well recovery rates.
If you’ve only ever lived on city water and sewer, this probably sounds like a lot. It’s really just two extra steps to add to your closing checklist, and neither one is complicated.
Why Are Private Wells So Common Along the Front Range?
A lot of foothill and plains communities were built before municipal water and sewer lines ever reached them. In many unincorporated areas, they still haven’t. Rather than being some rare setup, private wells are just how thousands of Colorado homes have always worked and still do.
That means it’s not a red flag by itself. It just comes with its own maintenance rhythm and its own set of things to check before you buy, the same way a home on city utilities has its own set of things to watch.
Do Home Inspectors Check Well Systems?
We confirm water pressure at fixtures (typically checking for 40/80 PSI at a minimum of one fixture) and perform a functional flow test. This approach tells you the well was producing water during the inspection. That said, it is not a well certification and it doesn’t mean the pump, motor, or well components were evaluated. A well that’s flowing normally during your inspection can still fail weeks or months later.
At Axium, we can also tell you whether the water is safe to drink through water well testing. Some of the things we test for include:
- Domestic water quality
- Lead
- Nitrates
- Radon
- Bacteria, such as e. coli and coliform
Front Range groundwater can carry high mineral content. In some foothill areas, trace uranium or arsenic can appear. None of that has a taste or smell, so testing is recommended. It’s the only way to know for sure what’s coming out of the tap.
How Much Does Water Testing Cost?
Plan on $400 to $700 for a state-certified water testing lab. Think of it less as extra spending and more as filling in the blanks a normal inspection leaves open. Most buyers who skip this step aren’t trying to save money on purpose. They just didn’t know the gap existed until it was too late to act.
What Do Well Repairs Cost in Colorado?
Well pump replacement runs $1,200 to $3,000, and a pressure tank replacement is $400 to $900. Note that the exact price can vary depending on the home’s set-up and location.
Axium Inspections regularly evaluates properties that have wells throughout Denver, Jefferson, Adams, and Arapahoe counties, where these systems have quietly kept thousands of homes running long before municipal utilities ever showed up. But you will still want a well specialist to fully evaluate the system.
Frequently Asked Questions
What well water problems are common in Front Range homes?
High total dissolved solids from mineral-heavy groundwater, bacteria from shallow wells, or poorly sealed casings. None have a detectable taste or smell, which is why testing matters.
Can I negotiate repairs if the well has problems?
Yes. Well pump replacement and pressure tank replacement are legitimate negotiation points if testing or inspection turns up an issue.
Do storage tanks or cisterns affect well testing?
Yes. A storage tank or cistern can distort the results of a 2-hour flow test, because the tank drains before the well is ever forced to refill it. That means the test measures the tank’s stored water rather than the well’s true recovery rate. If your property has a storage tank, flag it to your inspector in advance so testing can be planned around it.
What does a filtration system on a well mean for water quality?
It’s not necessarily a problem. A reverse osmosis or other filtration system is a common upgrade. However, water testing should always be performed at the source, before filtration, since testing water that’s already been filtered won’t reflect what’s actually in the ground.
