Hartman, Colorado Well Depths, Yields, and Costs

How deep are wells around Hartman?

How much water do wells make near Hartman?

Hartman well depths and the plains geology

Hartman wells are commonly shallow. Records put 45% under 100 feet and another 46% between 100 and 300 feet. The 90th-percentile depth is 272 feet, while the deepest record reaches 1,094 feet. That range matters when comparing drilling bids: a bid based only on the 119-foot median may not cover an unusually deep hole.

The records identify 226 wells with an unnamed or fractured-bedrock aquifer, along with 14 in the Ogallala and 3 in the Dakota Sandstone. Hartman sits on plains alluvium and sedimentary rock, so local material, the target aquifer, casing, and grout requirements can change the final design.

How much water Hartman wells produce

The reported yield numbers are unusually strong, but they come from only 30 wells. The median reported yield is 650 gallons per minute, with the middle half from 16.2 to 1,209 gallons per minute. The records show 77% of reported wells at 15 gallons per minute or more, and 23% between 5 and 15 gallons per minute.

No reported well falls under 5 gallons per minute in this dataset. That does not mean every new domestic well will produce that much. The sample includes a large irrigation share, and irrigation wells can be designed and tested differently from household wells. Ask for the completion report and pumping test for nearby domestic wells before relying on the high median.

Hartman water levels and what the records show

Only 1 well reports a static water level, so the available water-level evidence is very limited. Its reported depth to water is 50 feet, and the listed median and middle-half figures are also 50 feet. That single observation cannot establish a water-table trend for Hartman, Granada, or nearby properties.

The permit history does not provide a decade-by-decade water-level series. It therefore cannot support a claim that groundwater is falling or stable. A driller can check nearby completion records, and a buyer should ask for a recent measurement from the property or neighboring wells. Water level, pumping drawdown, and seasonal conditions are separate questions.

Hartman permit history and the drillers in the records

Hartman-area permits span the 1950s through the 2020s, with the newest permit year listed as 2020. The busiest decades in the supplied records were the 2000s with 41 permits, followed by the 2010s with 27. The 1960s had 25, while the 1990s had 22.

The most frequently listed drillers are Ark Valley Pump & Supply (Smith Jr., William), with 25 records; Authorized (Pe, Pg), with 22; and Ark Valley Pump & Supply (Smith, William David), with 18. These names describe permit history, not a recommendation or proof of current availability. Check the current permit status and talk with a licensed driller before scheduling work.

What a new Hartman well may cost

For Hartman’s alluvium and plains sedimentary rock, the supplied drilling model uses $35-$55 per foot. At the local median depth of 119 feet, that puts the drilled hole at about $4,200-$6,500. This is the hole only, not the complete water system.

A finished well with pump, pressure tank, trenching, and electrical is estimated at $10,200-$18,500. A deeper-than-typical hole, difficult access, casing or grout changes, water treatment, or an unusual pump setup can move the price. Get the bid in writing and ask what footage, casing, testing, electrical, trenching, and restoration are included.

Hartman risks to check before buying or building

Low yield is not the only concern. The records include 4 PFAS sampling or contamination sites, 1 historic mine-features site, and 1 EPA Superfund or cleanup site within about 10 miles. These mapped sites do not establish contamination at a particular parcel, but they are a reason to review environmental records and test the water after closing.

Also verify septic setbacks, the proposed home location, driveway access, and room for a well-service truck. Colorado DWR permits control how a well may be used. Household-use wells are commonly exempt wells, but the permit conditions still matter, and the general exempt-well pumping limit is 35 gallons per minute. A new build may also need an augmentation plan in an over-appropriated basin.

Buying land near Hartman, Granada, and Holly

Before buying, pull the closest well permits and separate domestic, stock, irrigation, and monitoring wells. Hartman’s records are 57% irrigation, 16% stock, 17% monitoring, and 12% domestic or household. That mix explains why a large reported yield should not be treated as a household guarantee.

Have a local driller review the parcel, access, likely depth, aquifer target, and neighboring completions before you remove a well contingency. For context, Granada is 6 miles away, Holly is 7 miles, and Lamar is 22 miles; those areas can provide additional records, but geology and permitted use still need to be checked at the actual lot.

What a new well costs in Hartman, 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 (162 ft) would run roughly $11,670–$20,910. 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 Hartman? 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 Hartman 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.
