What Aspen Wells Cost, Yield, and Require

How deep are wells around Aspen?

How much water do wells make near Aspen?

Aspen well depths vary with mountain bedrock

The median recorded well depth near Aspen is 127 feet. The middle half runs from 63 to 260 feet, so a proposed well near the median is not unusual, but a bid should allow for meaningful variation. Forty percent of recorded wells are under 100 feet, while 38% fall between 100 and 300 feet. Another 20% are between 300 and 600 feet, and 2% exceed 600 feet.

The deepest recorded well is 1,510 feet. These results fit Aspen’s fractured mountain bedrock, including granite and gneiss. Fractures control where water is found, so depth can change sharply from one lot to the next. When comparing bids, ask what footage is included, how casing and grout are handled, and what happens if the hole must continue beyond the planned depth.

Most Aspen wells produce useful flow, but verify the lot

Among the 291 Aspen-area records that report pump yield, the median is 15.0 gallons per minute. The middle half is 10.0 to 17.0 gallons per minute. Sixty-seven percent report more than 15 gallons per minute, while 24% fall between 5 and 15 gallons per minute. Six percent report 1 to 5 gallons per minute, and 2% report less than 1 gallon per minute.

That distribution is encouraging for ordinary household planning, but the yield record is incomplete and a test result is not the same as guaranteed long-term supply. A low-yield well may still work with storage and careful demand management, while a higher-yield result does not replace water-quality testing. Confirm the actual well test, pump size, storage tank, and permitted use before relying on a seller’s description.

Aspen water levels are shallow in the records, not a proven trend

Only 59 permitted wells near Aspen report a static water level, so the water-level sample is much smaller than the depth sample. The reported median depth to water is 41 feet, with the middle half between 14 and 100 feet. In practical terms, many reported wells encountered water relatively close to the surface, but that does not establish the water level on every parcel.

The available facts do not provide a decade-by-decade static-water series, so they do not show a defensible rising or dropping trend. Ask for the well’s static level, pumping level, and test date rather than assuming nearby records apply directly. In fractured rock, water levels and production can depend on local fractures, elevation, recharge, and seasonal conditions.

Aspen’s permit history shows long local drilling experience

Permit records near Aspen reach back to the 1950s and include a newest permit year of 2025. The largest decade in the record is the 1990s, with 410 permits. The 1980s account for 204, the 2000s for 237, and the 2010s for 151. The 2020s account for 103 permits so far in the record.

The most active named drillers are Shelton Drilling Corporation, with 480 records; Steve Shelton Drilling, Inc., with 119; and Collins Drilling Co, with 95. Those records show who has worked in the area, not a guarantee of current availability or performance. Before hiring anyone, check licensing, insurance, references for comparable fractured-rock sites, and the written scope for drilling, casing, grout, testing, and pump installation.

Budget Aspen drilling separately from the finished water system

For Aspen’s fractured mountain bedrock, the cost model uses $65 to $100 per foot. At the 127-foot median depth, the drilled hole is estimated at about $8,300 to $12,700. That is only the hole. A finished system with pump, tank, trenching, and electrical is estimated at $14,300 to $24,700.

A buyer should treat those figures as planning ranges rather than a fixed quote. Depth beyond the median, difficult access, casing and grout requirements, disposal, electrical distance, and a low-yield design can change the final price. Ask whether the proposal covers a pump test and what is excluded. On a raw lot, also price the access driveway, site development, septic system, and utility routing separately.

Check water quality, dry-hole risk, and septic fit

Aspen records identify 1,554 wells with unnamed or fractured-bedrock aquifers, 39 in the Mancos aquifer, and 22 in alluvial aquifers. The area also has 14 PFAS sampling or contamination sites, 129 historic mine features, and 2 EPA Superfund or cleanup sites mapped within about 10 miles. These locations do not prove a problem at a specific parcel, but they are reasons to test instead of assuming well water is safe.

Request a current laboratory test and review nearby mine, cleanup, and septic information. Confirm setbacks and soil suitability for a new septic system before building. Also check the permit’s use: 66% of the records are domestic or household, while other permits serve stock, irrigation, or monitoring purposes. A well permit is not a substitute for confirming the legal household supply and the planned building use.

Use neighboring wells to plan an Aspen purchase

Start with the exact parcel’s DWR permit, construction report, pump test, static water level, and water-quality results. Then compare nearby wells rather than relying only on the regional median. The Aspen-area record shows a 127-foot median depth and 15.0-gallon-per-minute median yield, but fractured granite and gneiss can make one lot perform differently from the next.

For a vacant lot, have a licensed driller review access, likely casing and grout, estimated depth, and the consequences of a dry or low-yield hole. Confirm the permit path and any augmentation requirements if the basin or proposed use calls for them. A domestic or exempt household-use well is still subject to its permit conditions and the 35-gallon-per-minute exempt-well pumping limit. Build the well, septic, driveway, and house plan together.

Well permits by decade near Aspen

What a new well costs in Aspen, CO

How this is built: the median permitted depth here times the per-foot range for this ground, plus the normal system costs. A lot at the 75th-percentile depth (260 ft) would run roughly $22,900–$38,000. See the full Colorado well cost guide.

Environmental sites mapped within about 10 miles

Counts come from EPA, USGS and state datasets layered on the Colorado Well Finder map. A count is not a verdict on any one well; it tells you what to test for.

Buying land near Aspen? Know what it costs to build before you buy the dirt.

A listing photo can't tell you whether a lot is a dream or a money pit. Two parcels near Aspen can carry the same asking price while one needs an $80,000 driveway and a $45,000 engineered septic the other doesn't. The well numbers on this page are the start of that answer. A Tri-Lakes Site Feasibility Report is the rest of it: a licensed general contractor, excavator and septic installer reads the parcel the way we would if we were about to build on it, and puts the real cost in writing before your money is committed.

Spend a little to know. Or gamble a lot to guess. Realtors sell the view and inspectors look at houses that already exist. We're the people who'd build it, so we catch what quietly turns a "great deal" into a budget disaster: bad access, buried rock, steep grade, soil that won't pass for a normal septic, water that's a fortune to reach. And if the lot is good, you've already got a builder ready to do the work, driveway to drywall.

• Instant Online Report, $99 — type the address and get a buildability read on the spot: parcel, terrain and slope, soil and septic outlook. Cheap enough to run on every lot you're shopping.
• Desktop Report, $500 — a contractor's from-the-desk feasibility read: Regulation 43 and county code, GIS parcel data, terrain, flood and drainage, soil and septic viability, setbacks and buildable envelope, nearby well depths from our 591,000-well database, the likely driveway route, and a preliminary site-development cost breakdown.
• On-Site Report, $2,000 — everything above, then boots and a drone on the actual ground: house pad and septic zone located, access and winter conditions checked, rock and soil observed in person, a 15 to 20 page written opinion you can hand a lender or seller. Credited toward your project if you build with us.

Under contract, comparing parcels, or a realtor with a rural listing whose buyers keep asking "what will it cost to build here?" This is the due-diligence step almost everyone skips, and the one that saves the most.
