What Evans, Colorado Wells Are Really Like

How deep are wells around Evans?

How much water do wells make near Evans?

Evans wells are usually shallow, but the range is wide

The median reported well depth near Evans is 49 feet. The middle half runs from 27 to 75 feet, and 90% of reported wells are under 100 feet. That pattern gives a driller a useful starting point for a bid, but it is not a promise for a particular lot.

The records also include wells reaching 900 feet. About 9% fall between 100 and 300 feet, and a smaller share is deeper. Evans sits on Denver Basin sedimentary bedrock, with permits commonly naming Denver Basin aquifer units. Local alluvial deposits and the exact location of water-bearing material can change the design, casing, grout, and final depth.

Reported Evans yields are generally strong

Among the 265 wells that report a pump yield, the median is 20.0 gallons per minute. The middle half is listed from 15.0 to 900.0 gallons per minute, and 82% report more than 15 gallons per minute. Only 3% report 1 to 5 gallons per minute, while none are recorded under 1 gallon per minute.

Those figures are encouraging for ordinary household planning, but the sample is much smaller than the total permit history. A reported yield is not the same as guaranteed long-term production. Ask for the well construction report, pump test information, permitted use, and any limits tied to the permit. An exempt household-use well is still subject to Colorado rules, including the 35 gpm pumping limit.

Evans water levels do not show a simple steady decline

The median static water level is 13 feet below the ground surface. The middle half of reported measurements is 8 to 19 feet, so many wells encounter water relatively close to the surface. That can reduce drilling depth, but shallow groundwater also deserves careful testing because it can be more exposed to nearby land uses.

The decade series does not show a straight downward trend. The median was 20 feet below surface in the 1960s, 9 feet in the 2010s, and 13 feet in the 2020s. Measurements come from different wells and locations, so treat this as local historical context rather than a prediction for a vacant parcel.

Permit activity continues around Evans

Evans has a long well-permit history, with permits issued from the 1950s through the 2020s. The newest permit in the records is from 2025. The 2020s account for 399 permits, compared with 357 in the 1990s, so recent activity is substantial.

The most active names in these records are Authorized (Pe, Pg), Clement, Glenn A., and Lesh Drilling Inc. (Lesh Jr., Ed). Those names describe permit history, not a recommendation or proof that a driller serves a particular property today. For a purchase, compare nearby construction reports rather than relying only on the driller name.

A typical Evans well costs more than the hole itself

The local drilling model uses a typical rate of $50 to $70 per foot in Denver Basin sedimentary bedrock. At the 49-foot median depth, the drilled hole works out to about $2,400 to $3,400. That is only the drilling portion.

A finished system, including the pump, pressure tank, trenching, and electrical work, is modeled at about $8,400 to $15,400. A shallow well can still require substantial site work, access, casing, grout, pump equipment, and utility connections. Get a written bid that identifies what is included and what happens if the driller must go deeper or the hole does not produce enough water.

Check water quality, septic room, and low-yield risk

Mapped environmental records within about 10 miles include 2,478 PFAS sampling or contamination sites, 14 historic mine features, and 4 EPA Superfund or cleanup sites. That does not prove a specific Evans well is contaminated, but it is enough reason to test before closing and to review the well location relative to nearby land uses. A qualified laboratory can identify the appropriate drinking-water panel.

Low yield and dry holes are still possible even though recorded yields are favorable. Before building, confirm the permitted use, well location, setbacks, septic area, driveway access, and available electrical service. Shallow water also makes careful septic design and maintenance important. If the basin is over-appropriated, an augmentation plan or other water-right requirement may affect what use is allowed.

What a new well costs in Evans, 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 (75 ft) would run roughly $9,750–$17,250. 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 Evans? 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 Evans 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.
