Wells in Monument, Colorado: Depth, Yield, and Cost

How deep are wells around Monument?

How much water do wells make near Monument?

Monument well depth is usually measured in hundreds of feet

Most wells around Monument are not shallow installations. The middle half runs from 270 to 420 feet, and 59% of reported wells are between 300 and 600 feet. Another 27% fall between 100 and 300 feet, while 8% exceed 600 feet. The deepest record reaches 2,500 feet, so the range is wide.

For a driller, a 320-foot median is a starting point for estimating footage, not a promise that your lot will match it. Local permits identify Dawson, unnamed fractured-bedrock, and Denver aquifers. Sedimentary Denver Basin conditions can still vary from one parcel to the next, and a fractured-bedrock interval may be less predictable. Ask for nearby completed-well depths rather than relying only on a countywide average.

Most Monument wells report a workable household yield

Among wells with reported pump yields, the median is 11.0 gallons per minute, and the middle half falls between 10.0 and 12.6 gallons per minute. That is a fairly narrow central range for planning ordinary household use. A large majority, 83%, report yields from 5 to 15 gallons per minute, while 16% report more than 15 gallons per minute.

Only 1% report 1 to 5 gallons per minute, and none are recorded under 1 gallon per minute. That does not eliminate risk on an individual lot. A pump test, storage-tank sizing, and the well permit’s allowed use matter more than the area median. Most permits are for domestic or household use, so do not assume an existing domestic well can support irrigation or other expanded demands.

Monument water levels fluctuate without a simple downward trend

Reported static water levels have a median depth of 120 feet below the surface, with the middle half between 90 and 169 feet. A buyer should treat that as the depth to water when the well was measured, not as the pump setting or a guaranteed future level.

The decade series does not show a steady drop. Median depth was 110 feet in the 1970s, 150 in the 1980s, 120 in the 1990s, 128 in the 2000s, 110 in the 2010s, and 130 in the 2020s. The measurements move up and down rather than forming a consistent decline. Differences in location, season, well construction, and measurement conditions can affect the comparison. Check the actual well log and recent performance for the property you are considering.

Monument has a long permit history and several active drillers

The records cover a substantial build-out period around Monument. Permits increased from 40 in the 1950s and 57 in the 1960s to 616 in the 1970s, 869 in the 1980s, and 1,402 in the 1990s. Permit activity was 1,058 in the 2000s, 684 in the 2010s, and 537 in the 2020s. The newest permit year in the records is 2026.

For local history, the most represented drillers are Fletcher Drilling with 1,562 records, Kunau Drilling LLC with 1,108, and Hamacher Well Works Inc with 589. These counts identify activity in the records, not a recommendation or a guarantee of current availability. Before buying, pull the DWR construction report, permit, production information, and any abandonment record for the specific well.

A median-depth Monument well can cost $22,000 to $34,400 finished

The local cost model uses a typical drilling rate of $50 to $70 per foot in Denver Basin sedimentary bedrock. At the 320-foot median depth, the drilled hole works out to about $16,000 to $22,400. That is not the complete project price.

A finished well with pump, pressure tank, trenching, and electrical is modeled at approximately $22,000 to $34,400. The final bid can move with actual depth, casing and grout requirements, access, power distance, site conditions, and equipment choices. Ask each driller to separate footage, casing, development, pump equipment, trenching, electrical, testing, and permit-related work. A shallow-looking parcel is not automatically cheaper if access or utility work is difficult.

Check water quality, dry-hole exposure, and septic layout early

Mapped environmental information within about 10 miles includes 31 PFAS sampling or contamination sites, 6 historic mine features, and 3 EPA Superfund or cleanup sites. A mapped site does not prove contamination at your parcel, but it is a reason to review location, drainage, land use, and available water-quality data. Test an existing well before relying on it.

Low yield and a dry hole remain practical risks even where area statistics look favorable. Septic setbacks, replacement-area needs, driveway access, building placement, and well equipment space should be reviewed together. The well permit controls the authorized use. In an over-appropriated basin, an augmentation plan may be required for some uses, so confirm the water-rights position with Colorado DWR and a qualified water-rights professional before designing irrigation or additional residences.

Use nearby records before buying a Monument lot

Start with the closest comparable wells, not every permit within the five-mile search area. Compare depth, aquifer name, construction date, static water level, yield, and intended use. Woodmoor is about 2 miles away, Gleneagle about 3 miles, and Palmer Lake about 5 miles; Air Force Academy, Black Forest, and Larkspur provide additional regional context at 6, 9, and 11 miles.

For an existing home, obtain the well permit and construction report, have the water tested, and confirm the pump can meet the household’s demand. For vacant land, price a site-specific drilling investigation and keep enough room for the well, septic system, replacement area, driveway, and house. A driller’s estimate based on the 320-foot median is useful for budgeting, but the actual neighboring logs and the parcel’s legal water supply should control the decision.

What a new well costs in Monument, 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 (420 ft) would run roughly $27,000–$41,400. 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 Monument? 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 Monument 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.
