Fairmount, Colorado Well Depth, Yield, and Cost

How deep are wells around Fairmount?

How much water do wells make near Fairmount?

Fairmount well depth: shallow records, deep exceptions

The recorded median well depth near Fairmount is 39 feet. The middle half runs from 24 to 125 feet, so a driller's bid based only on the median can be misleading. Seventy percent of recorded wells are under 100 feet, while 14% fall from 100 to 300 feet, 12% from 300 to 600 feet, and 5% are 600 feet or deeper.

The 90th-percentile depth is 400 feet, and the deepest well on record is 1,985 feet. That spread points to substantial variation across short distances. Most permits name an unnamed or fractured-bedrock aquifer, with 5,015 wells in that category. Fractured bedrock can be unpredictable, so look at nearby completed wells and their construction reports before accepting a drilling estimate.

How much water Fairmount wells make

Among the 433 wells that report a pump yield, the median is 10.0 gallons per minute. The middle half runs from 6.0 to 14.0 gallons per minute. Sixty-six percent report yields from 5 to 15 gallons per minute, and 21% report more than 15 gallons per minute.

Low-producing wells are present but not dominant: 10% are in the 1-to-5-gallon-per-minute range and 3% are under 1 gallon per minute. For a buyer, the important limitation is the small reporting pool compared with the total permit record. Ask for the well permit, construction report, pump information, and any production testing rather than relying on a regional median.

Fairmount water levels and the recorded trend

The current combined static-water-level record has a median depth to water of 16 feet, with the middle half from 9 to 62 feet below the surface. That is a measurement taken when a well was static, not a guaranteed pumping level. A pump, storage tank, pressure system, and household demand can all affect how the water system performs.

The decade series does not show a simple steady decline. The median was 24 feet below surface in the 1960s, rose to 118 feet in the 1970s, then measured 13 feet in the 2010s and 12 feet in the 2020s. Only 111 wells report a static water level, so treat the series as local record context, not a site-specific forecast.

Fairmount drilling history and the active names

Permitting has continued through 2025. The record shows 244 permits from the 1950s, 325 from the 1960s, 556 from the 1970s, 415 from the 1980s, 1,047 from the 1990s, 807 from the 2000s, 697 from the 2010s, and 289 from the 2020s. Domestic or household use accounts for 49% of the use mix, while monitoring wells account for 32%.

The most active driller names in these records are Authorized (Pe, Pg), with 1,216 records; Adams Water Well Drilling (Adams, George E), with 162; and John'S Drilling Inc. (John, Lloyd), with 156. Those counts describe permit records, not a current recommendation or proof that a driller is available for a new project.

What a new Fairmount well may cost

The local drilling model uses a typical rate of $50 to $70 per foot in Denver Basin sedimentary bedrock. At the 39-foot median depth, the drilled hole works out to about $2,000 to $2,700. That is only the hole, not the complete water system.

A finished well with pump, tank, trenching, and electrical is modeled at about $8,000 to $14,700. The depth range matters: a parcel near the 400-foot 90th percentile will not price like a median-depth job. Get a written bid that identifies drilling depth assumptions, casing and grout, pump equipment, trench length, electrical work, testing, and what happens if the hole is dry or produces less than expected.

Fairmount risks to check before closing

Water quality deserves its own investigation. Within about 10 miles, the mapped environmental record includes 308 PFAS sampling or contamination sites, 164 historic mine features, and 46 EPA Superfund or cleanup sites. These mapped sites do not establish contamination at a specific property, but they are a reason to test the existing well and understand the property's location relative to them.

Low yield, a dry hole, poor construction, and septic setbacks can also affect a building plan. Confirm the DWR permit and use limits, inspect casing and grout information, and have the existing pump system evaluated. If the property needs a new septic system, verify that the proposed house, well, septic area, driveway, and other improvements can fit together before buying.

A practical Fairmount plan for buyers and builders

Start with the nearest permitted wells, not just the regional statistics. Compare their depths, reported yields, static levels, aquifer descriptions, and construction records. Records from Golden, Wheat Ridge, Arvada, Applewood, West Pleasant View, and East Pleasant View can add context, but the closest comparable wells deserve the most attention.

For an existing home, make the purchase contingent on reviewing the permit, testing the water, checking flow and pressure, and confirming the well's permitted use. For raw land, price the likely complete system rather than only drilling. Colorado DWR permitting, household-use exemptions, pumping limits, augmentation requirements in over-appropriated basins, and septic approval can all affect what the lot can support. Have the driller and septic designer review the site together.

Well permits by decade near Fairmount

What a new well costs in Fairmount, 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 (125 ft) would run roughly $12,250–$20,750. See the full Colorado well cost guide.

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 Fairmount? 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 Fairmount 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.
