What Jansen, Colorado Wells Are Really Like

How deep are wells around Jansen?

How much water do wells make near Jansen?

Jansen well depth depends on the local sediments and bedrock

Jansen wells have a median reported depth of 70 feet. The middle half runs from 27 to 205 feet, so a driller bidding a new well here may be looking at a shallow alluvial or plains-sediment hole, but should not assume every site will be that simple. The 90th-percentile depth is 388 feet, and the deepest record reaches 1,000 feet.

About 58% of recorded wells are under 100 feet, while 24% fall between 100 and 300 feet. Another 15% are between 300 and 600 feet, and 3% are deeper than 600 feet. Most permits name an unnamed or fractured-bedrock aquifer. That geology can make nearby well results uneven, especially where a site depends on fractures rather than a consistent shallow water-bearing layer.

What a Jansen well may produce

The reported median yield is 6.0 gallons per minute, with the middle half between 2.5 and 7.6 gallons per minute. That is a workable range for many household uses, but it is not the same as unlimited water. Only 32 wells in the records report a pump yield, so the sample is limited.

Production is strongest in the 5-to-15-gallon-per-minute category, which contains 56% of reported yields. Another 28% are between 1 and 5 gallons per minute, 9% exceed 15 gallons per minute, and 6% are under 1 gallon per minute. A buyer should ask for the actual well test, recovery information and storage capacity. A low-yield well may still work with adequate tank storage, while a strong reported yield does not guarantee the same result on the next parcel.

Jansen water levels and what the records can tell you

Reported static water levels have a median depth of 35 feet, with the middle half from 22 to 37 feet below ground. That suggests many measured wells encounter water fairly close to the surface, even though total drilled depth varies considerably. Static level is not the same as pumping level, and it can change with season, nearby pumping and the time allowed for a well to recover.

Only 30 wells report a static water level, so this dataset is too small to establish a dependable long-term trend for Jansen. The permit counts also do not measure groundwater decline. Have the seller provide a current water-level measurement and pumping test where available. If you are planning a new well, a local driller can compare nearby completions in Jansen, Starkville, Trinidad and Cokedale without treating one neighboring well as proof of your site’s result.

Who has drilled around Jansen, and when

The permit history shows activity across several generations. Records include 6 permits from the 1950s, 4 from the 1960s, 8 from the 1970s, 11 from the 1980s, 103 from the 1990s, 61 from the 2000s, 83 from the 2010s and 26 from the 2020s. The newest permit year in the records is 2025. That history shows a substantial concentration of development after the 1980s, not a uniform pace through time.

The most active named driller records are Boday Well Drilling with Alex Boday listed on 56 wells and Kathleen Boday listed on 42. Authorized (Pe, Pg) appears on 55 records. These names can help when comparing construction styles or asking for local references, but a permit history is not a recommendation. Verify licensing, insurance, scope and the proposed casing and grout details before hiring.

Jansen well drilling cost at the typical depth

For Jansen’s alluvium and plains sedimentary rock, the drilling model uses a typical rate of $35 to $55 per foot. At the 70-foot median depth, the drilled hole works out to about $2,400 to $3,800. That is only the hole. It does not cover the complete water system needed to use the well.

The modeled finished-well cost is about $8,400 to $15,800, including the pump, pressure tank, trenching and electrical. A contractor’s bid can move outside that range if the well needs more depth, different casing or grout, difficult access, additional trenching or treatment equipment. Ask for a written breakdown separating drilling, casing, grout, development, pump installation, electrical and testing. The deepest recorded wells show why a shallow-depth allowance should not be treated as a guaranteed final price.

Jansen risks: water quality, low yield and site layout

Permit records identify 117 PFAS sampling or contamination sites within about 10 miles of Jansen, along with 224 historic mine features. There are 0 EPA Superfund or cleanup sites in that mapped area. Those figures do not tell you whether a particular well is contaminated, but they are a reason to test existing well water and review the property’s location and past use.

Low yield and dry-hole risk remain separate from water quality. A well can be deep and still produce poorly, or a shallow well can need careful protection from surface entry. Check casing, grout, wellhead drainage and the distance from septic components. Colorado DWR permit terms matter too: domestic or household wells have defined uses, and an exempt well is subject to the 35-gallon-per-minute pumping limit. Confirm water rights and any augmentation requirement before planning irrigation, multiple homes or other expanded use.

Before buying or building on a Jansen lot

Start with the exact parcel, then pull every nearby permit rather than relying on a countywide average. Focus on reported depth, aquifer name, yield, static level, construction notes and the well’s permitted use. The local records show 358 wells, but only 176 are recorded as constructed, 236 report total depth, 32 report pump yield and 30 report static water level. Missing data is common.

For an existing home, require a current flow or pressure check, laboratory water testing and a review of the pump, tank, electrical service and septic system. For vacant land, confirm access for a rig, likely well location, septic setbacks, building envelope and the DWR permit path before closing. A driller should inspect the site and discuss a contingency if the first hole is dry or produces less than the home requires. Do not price the entire project from drilling footage alone.

Well permits by decade near Jansen

What a new well costs in Jansen, 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 (205 ft) would run roughly $13,175–$23,275. 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 Jansen? 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 Jansen 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.
