Northglenn Colorado Well Depth, Yield and Cost

How deep are wells around Northglenn?

How much water do wells make near Northglenn?

Northglenn well depths vary sharply across the plains

Northglenn's median reported well depth is 32 feet. That shallow median is driven by the depth mix: 67% of reported wells are under 100 feet. Still, the middle half spans 20 to 300 feet, so a nearby address can need substantially more drilling than the median suggests. Another 17% fall between 300 and 600 feet, while 10% are 600 feet or deeper. The deepest record is 1,655 feet.

For a driller's bid, do not price a property from 32 feet alone. Ask which nearby wells are comparable in aquifer, intended use and construction. Permits name unnamed or fractured-bedrock aquifers most often, with alluvial and Laramie Fox Hills wells also present. Denver Basin aquifer wells account for 100% of the records.

Reported Northglenn well yields are generally usable

Among the 353 wells reporting a pump yield, the median is 12.0 gallons per minute, with the middle half between 10.0 and 15.0 gallons per minute. Sixty-six percent report 5 to 15 gallons per minute, and 31% report more than 15 gallons per minute. No reported wells are under 1 gallon per minute, while 3% fall between 1 and 5 gallons per minute.

That is a favorable screening picture for ordinary household demand, but it is not a promise for an untested lot. Yield depends on the completed interval, pump setting, storage and well construction. Confirm the permitted use with Colorado DWR. An exempt household-use well has a 35 gallon-per-minute pumping limit, even if the aquifer could produce more.

Northglenn water levels look broadly stable by decade

Reported static water levels are relatively shallow in this record set. The median depth to water is 12 feet, and the middle half is 9 to 31 feet below the surface. That matters during construction because shallow water can affect drilling methods, casing, grout and excavation planning.

The decade medians do not show a clear long-term decline: measurements from the 2000s have a median of 14 feet, compared with 11 feet in the 2010s and 12 feet in the 2020s. These are reported static measurements from 134 wells, not a continuous monitoring network. A buyer should still ask for the specific well's static level and test conditions rather than treating the area median as a guarantee.

Northglenn has a long permit history and several active names

Permit activity stretches from the 1950s through the newest permit year, 2025. The records show 98 permits in the 1950s, 123 in the 1960s, 289 in the 1970s, 300 in the 1980s, 634 in the 1990s, 890 in the 2000s, 675 in the 2010s and 440 in the 2020s. That history gives a buyer more local comparisons than a newer rural subdivision would.

The most active names in the records are Authorized (Pe, Pg), John'S Drilling Inc. (John, Lloyd) and Waneka & Son Drilling (Waneka, Don). Treat permit history as a research lead, not a recommendation. Check the original permit, construction report, completion details and any available pump test for the wells near your lot.

Northglenn drilling cost depends on the final depth

The local cost model uses a typical drilling rate of $50 to $70 per foot in Denver Basin sedimentary bedrock. At the 32-foot median depth, the drilled hole models to about $1,600 to $2,200. A finished well, including pump, tank, trenching and electrical, models to about $7,600 to $14,200.

Those figures are planning ranges, not a fixed bid. A property that follows the 300-foot upper end of the middle range will require a different drilling budget than one near the median. Get the driller to separate footage, casing, grout, pump equipment, trenching, electrical work and any difficult access or construction conditions. Depth records near Thornton, Federal Heights, Broomfield and Westminster can help establish local context, but not a guaranteed price.

Check water quality, yield and site constraints before closing

Water quality deserves specific attention in Northglenn. Mapped environmental records within about 10 miles include 691 PFAS sampling or contamination sites, 55 EPA Superfund or cleanup sites and 30 historic mine features. Those mapped sites do not prove contamination at a particular well, but they are a reason to review state records and order testing suited to the property's location and history.

Low-yield and dry-hole risk cannot be eliminated by an area median. Only 353 wells report pump yield, and reported depths vary widely. Before building, confirm well location, setbacks, casing and grout, septic separation, access for a rig, electrical routing and the legal water use. In an over-appropriated basin, an augmentation plan may be needed for some uses.

Use nearby records before buying or building in Northglenn

Start with the exact parcel, then compare nearby permits rather than relying on the area's 32-foot median. Look for wells with similar depth, aquifer name, use and construction date. The records include a large monitoring share—49%—alongside domestic or household wells at 30%, so not every nearby point represents a home water supply.

For a purchase, make well inspection, water-quality testing and a pump or flow test part of due diligence. For a new build, have a licensed driller review access, expected depth, casing, grout and pump sizing before finalizing the house location. Also confirm septic feasibility and the permitted use with Colorado DWR. Nearby Thornton, Federal Heights, Broomfield, Westminster, Shaw Heights and Welby can provide comparison records, but the lot itself controls the final result.

Well permits by decade near Northglenn

What a new well costs in Northglenn, 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 (300 ft) would run roughly $21,000–$33,000. 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 Northglenn? 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 Northglenn 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.
