How deep are wells around Valmont?

How much water do wells make near Valmont?

Valmont well depth depends on the ground below the lot

Valmont’s reported well depths are unusually spread out for a mountain-area setting. The median is 35 feet, and the middle half falls between 20 and 200 feet. About 65% of reported wells are under 100 feet, while 21% fall from 100 to 300 feet and 14% from 300 to 600 feet. One percent are 600 feet or deeper, with the deepest record reaching 3,000 feet.

The local geology helps explain the uncertainty. Permits most often name an unnamed fractured-bedrock aquifer, with 4,917 wells in that category. Fractured granite and gneiss can produce water through cracks rather than through a uniform layer, so two nearby lots may not drill alike. A driller’s bid should state the assumed depth, casing and grout work, and what happens if the hole must go deeper.

What a Valmont well may produce

Among the 568 records that report a pump yield, the median is 10.0 gallons per minute. The middle half produces 7.0 to 15.0 gallons per minute. About 63% fall in the 5 to 15 gallons-per-minute range, and 27% report more than 15 gallons per minute. Eight percent are between 1 and 5 gallons per minute, while 1% are under 1 gallon per minute.

That is a useful local benchmark, not a promise for a particular lot. A yield test, storage tank, and pump setup determine how comfortably a home can use the water during peak demand. An exempt household-use well also has a 35-gallon-per-minute pumping limit. Ask for the well construction report and pumping information instead of relying on a seller’s verbal description.

Valmont water levels look shallow, without a simple decline

Reported static water levels are shallow in this area. The median depth to water is 10 feet, and the middle half is 6 to 20 feet below the surface. That can reduce lift for a pump, but it also means groundwater and surface activities deserve attention during site planning.

The decade figures do not show a steady downward trend. Median measurements were 16 feet in the 1950s, 25 in the 1960s, 22 in the 1970s, 6 in the 2000s, 9 in the 2010s, and 9 in the 2020s. Measurements come from different wells and dates, so they are a regional reference rather than a water-table guarantee for your parcel. Confirm the current static level and seasonal behavior on the property.

Permit history and drillers around Valmont

Permit activity stretches across several generations. The records show 279 permits from the 1950s, 266 from the 1960s, 578 from the 1970s, 451 from the 1980s, 921 from the 1990s, 631 from the 2000s, 604 from the 2010s, and 543 from the 2020s. The newest permit year is 2025.

Those records cover domestic and household use most often, at 48%. Monitoring wells account for 33%, while stock and irrigation make up 3% and 2%. The most active named drillers are Authorized (Pe, Pg), Waneka & Son Drilling, and Ground Water Systems Inc. A permit is not the same as a completed, productive well, so check construction records and the permit’s permitted use before treating it as evidence for a home site.

Valmont well drilling cost: a useful planning range

For Valmont’s fractured mountain bedrock, the cost model uses a drilling rate of $65-$100 per foot. At the 35-foot median depth, the drilled hole models to about $2,300-$3,500. That is only the hole. A finished well with pump, pressure tank, trenching, and electrical models to about $8,300-$15,500.

Depth is only one part of the bid. Casing, grout, access for the rig, difficult rock, water testing, and the final pump arrangement can change the total. The local depth distribution is the reason not to budget from the median alone: the middle half extends to 200 feet, and some records are far deeper. Get a written estimate that separates drilling from completion and states the assumptions.

Risks to check before buying near Valmont

Environmental screening deserves more than a quick visual inspection. Within about 10 miles, the mapped data include 346 PFAS sampling or contamination sites, 460 historic mine features, and 63 EPA Superfund or cleanup sites. Those figures do not prove a problem at a particular address, but they support testing and a review of nearby land uses, drainage, and historic activity.

Low yield and dry holes remain possible in fractured bedrock, even where nearby wells perform well. Test existing water for appropriate contaminants and inspect the wellhead, casing, grout, pressure tank, and treatment equipment. Septic setbacks, replacement areas, access for drilling, and the location of a future house can be just as important as the well itself. Confirm requirements with Boulder County and Colorado DWR before closing or building.

A practical Valmont lot-checking plan

Start with the exact parcel, not a broad map point. Review nearby permits toward Boulder, Gunbarrel, Paragon Estates, Niwot, Pine Brook Hill, and Leyner, then compare reported depth, yield, aquifer name, use, and construction status. The 30% share of wells identified with Denver Basin aquifers is another reason to confirm the actual aquifer and permit conditions for the lot.

For an existing home, request the well permit, construction report, recent production information, water-quality results, and service history. For vacant land, have a licensed driller evaluate access and likely depth before setting a house or septic layout. Water rights can also control what a well may legally supply; over-appropriated basins may require an augmentation plan. Price the well, septic system, driveway, power, and site work together.

What a new well costs in Valmont, 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 (200 ft) would run roughly $19,000–$32,000. 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 Valmont? 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 Valmont 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.
