Leyner, Colorado Well Depth, Yield, and Drilling Costs

How deep are wells around Leyner?

How much water do wells make near Leyner?

Leyner well depth depends on the ground below the lot

The median reported well depth near Leyner is 56 feet. The middle half runs from 27 to 205 feet, meaning half of the wells with reported depths fall inside that range. The 90th percentile is 325 feet, and the deepest record reaches 1,400 feet.

Depths are spread unevenly. Fifty-six percent of records are under 100 feet, 29% are between 100 and 300 feet, 14% are between 300 and 600 feet, and 2% are 600 feet or deeper. That spread matters when you request a bid: a median-depth estimate may be reasonable for a first budget, but a driller still needs to account for the specific formation, access, casing, grout, and the chance that the well must go deeper.

Permits identify 82% of the wells with Denver Basin aquifers. Other records name an unnamed or fractured-bedrock aquifer, Alluvial water, or Laramie Fox Hills.

Most Leyner wells make usable flow, but records are limited

Among the 346 wells reporting a pump yield, the median is 10.0 gallons per minute. The middle half falls from 9.0 to 15.0 gallons per minute. Fifty-nine percent report between 5 and 15 gallons per minute, while 31% report more than 15 gallons per minute.

Low production is present but not common in the reported sample: 2% are under 1 gallon per minute and 8% are between 1 and 5 gallons per minute. A buyer should not treat the median as a promise. The well test, storage tank, pump setting, household demand, and permit conditions all affect how much water is practically available.

Colorado exempt household-use wells have a 35 gallon-per-minute pumping limit. A higher reported yield does not automatically mean the property can use that flow for irrigation or additional buildings. Confirm the permit and allowed uses with DWR before relying on the number.

Leyner water levels do not show a simple one-way decline

Reported static water levels are relatively shallow overall. The median depth to water is 14 feet, with the middle half from 9 to 27 feet below the surface. That can simplify pumping compared with a very deep water level, but it also means surface activities and construction practices deserve attention.

The decade figures do not establish a clean long-term decline. Median static water level was 20 feet in the 1960s, 25 feet in the 1970s, 35 feet in the 2010s, and 9 feet in the 2020s. The 2010s value was deeper than the earlier measurements, while the 2020s value was shallower.

These measurements come from only 91 records and may represent different wells, locations, and conditions. For a purchase, compare the target well's current water level and production test with nearby permits rather than using the decade series alone.

Permit activity runs from older wells to a 2026 record

Leyner has a long permit history. Records show 82 permits from the 1950s, 110 from the 1960s, 408 from the 1970s, 240 from the 1980s, 329 from the 1990s, 260 from the 2000s, 346 from the 2010s, and 278 from the 2020s. The newest permit year in the records is 2026.

The most frequently listed driller is Authorized (Pe, Pg), with 514 records. Waneka & Son Drilling (Waneka, Don) appears on 316, and Ground Water Systems Inc (Wilson, Richard R.) appears on 132.

Those names describe the permit history, not a recommendation or proof that a company is available for your project. Before closing, pull the actual permit, construction report, pump information, and any abandonment record for the target parcel. An old permit may not describe current equipment or current water quality.

A Leyner well budget starts with depth, then adds the system

The local cost model uses Denver Basin sedimentary bedrock and a typical drilling rate of $50 to $70 per foot. At the 56-foot median depth, the drilled hole works out to about $2,800 to $3,900. That is only the drilling portion.

A finished well with pump, pressure tank, trenching, and electrical is estimated at about $8,800 to $15,900 at that median depth. A deeper-than-typical hole can move the price well beyond that starting range, especially when access, casing, grout, difficult drilling, or additional site work is involved.

Ask bidders to separate drilling, casing and grout, pump equipment, tank, electrical, trenching, permits, testing, and any water-treatment work. On a rural lot, the cheapest drilling number is not necessarily the lowest complete project cost. Confirm what happens if the first hole has inadequate production or must be deepened.

Before building near Leyner, check water, waste, and the lot

Water quantity is only one risk. Mapped environmental information within about 10 miles includes 705 PFAS sampling or contamination sites, 103 historic mine features, and 23 EPA Superfund or cleanup sites. These mapped sites do not prove contamination at a particular property, but they are a reason to test the actual well and understand the local site history.

Low-yield wells and dry holes remain possible even where nearby records look favorable. Fractured-bedrock conditions can change over short distances. Ask for the well construction report, pump test, static water level, water-quality results, and maintenance history. Check neighboring wells near the parcel, not just a countywide average.

Before placing a house, septic system, driveway, or irrigation area, verify setbacks, drainage, access for a drilling rig, and the well permit's allowed use. An augmentation plan may be required in an over-appropriated basin. Confirm the building and septic layout before spending money on plans.

A practical purchase plan for a Leyner lot

Start with the parcel's permit number and locate the well on the ground. Compare its reported depth and production with nearby records in Leyner and surrounding areas such as Gunbarrel, Erie, Lafayette, Niwot, and Valmont. The local median yield is encouraging, but the relatively small number of yield reports means the target well's own test matters more.

For an existing home, make the contract review include the well permit, construction report, pump test, water-quality test, storage and pressure equipment, and septic records. For vacant land, get a driller's site review and a written estimate that identifies the assumed depth and what is excluded.

Do not design the house or septic field until access, setbacks, drainage, and water availability are confirmed. If the permitted use does not match your plans, resolve that with DWR before closing. A well that produces water is not automatically approved for every intended use.

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 Leyner? 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 Leyner 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.
