What Broomfield County Well Records Mean for Your Lot

How deep are wells around Broomfield County?

How much water do wells make near Broomfield County?

Why the 35 ft Median Is Not a Household-Well Bid

Depth is reported for 605 Broomfield County wells. The median is 35 ft, and the middle half runs from 20–200 ft. That spread alone makes a countywide average a weak basis for a fixed drilling budget. Monitoring wells dominate the use mix, so the shallow records should not be treated as a residential construction standard.

There is also a substantial deep-well group: 17% are at least 600 ft deep, and the 90th percentile is 880 ft. Permits name Alluvial and Laramie Fox Hills aquifers, while many leave the aquifer unnamed or use a fractured-bedrock category. Your target water-bearing formation and its depth beneath the lot matter more than the county median. Ask for a bid tied to comparable household wells.

Broomfield Yield Reports Leave Room for Caution

Only 76 wells report a pump yield. Their median is 10.0 gpm, with the middle half between 5.0–12.9 gpm. That is useful background, but it is a small slice of the permit inventory and not a promise of household supply.

The low end deserves attention: 13% of reported yields are under 1 gpm. A buyer looking at a well in that range needs a pumping and recovery test, along with an assessment of storage and household demand. A pump’s rated capacity is not the same as the well’s sustained production.

Before closing, compare the original yield report with current performance. Also verify permitted uses; having enough physical water does not automatically authorize irrigation or other outdoor use.

Shallow Water Readings Do Not Establish a Countywide Trend

The 49 reported static water levels have a median depth to water of 11 ft, with the middle half at 10–19 ft. Static level means the water level in a resting well. It is not the drilled depth, the thickness of the water-bearing formation or the level the water will hold during pumping.

These figures do not establish whether Broomfield County’s water table is rising or falling. The supplied records contain no water-level series by decade, and different well types can measure different groundwater conditions.

For a purchase, ask for dated measurements from the actual well and compare resting level, pumping level and recovery. A shallow resting level does not rule out weak production.

Permit Activity and the Names Behind the Records

Broomfield County has 1,102 permits on record, with 508 wells recorded as constructed. A permit count is not a count of operating household wells. Recorded issuance was highest in the listed decades during the 1990s, at 244, followed by 199 in the 2000s. The 2020s contain 136 permits, with the newest permit year listed as 2025.

The most frequent driller-field entry is “Authorized (Pe, Pg)” at 392 records; that label should not be treated as a drilling-company recommendation. Named drillers include Waneka & Son Drilling (Waneka, Don), with 54 records, and High Plains Drilling (Jecminek, Charles L.), with 43.

Use these entries to locate relevant completion reports, not to assume current availability or residential specialization.

What the Broomfield Drilling Estimate Includes

The cost model uses Denver Basin sedimentary bedrock and a drilling rate of $50–$70 per foot. At the county’s 35 ft median depth, that puts the drilled hole at about $1,800–$2,400. A finished well with pump, tank, trenching and electrical is estimated at $7,800–$14,400.

Those are median-depth model estimates, not a dependable budget for every residential lot. The monitoring-heavy inventory and the deep-well share make that distinction important. A household well targeting a deeper formation needs its own depth assumption and written estimate.

Have the driller identify casing and grout requirements, testing, equipment access and what happens if more drilling is needed. Keep the well quote separate from septic, driveway and house-site work.

Water Quality, Weak Wells and Site Constraints

The environmental map lists 1,390 PFAS sampling or contamination sites, 209 historic mine features and 188 EPA Superfund or cleanup sites within about 10 miles. These are screening records across the surrounding area—not proof that a particular Broomfield County well is contaminated. Sampling locations also do not necessarily indicate confirmed contamination.

Review the nearest mapped records and their actual findings, then arrange appropriate laboratory testing of the property’s water. Include routine drinking-water checks and discuss site-specific contaminants with the laboratory or reviewing agency.

For a new build, check well and septic placement before fixing the house footprint. Ask how the drilling contract handles an unsuccessful hole or inadequate yield, and preserve access for drilling and future well service.

Before Buying a Broomfield Lot on Well Water

Start with the parcel’s DWR permit, not the seller’s description of the well. Confirm authorized uses, construction documentation and whether the existing or proposed supply fits your plans. Household-use restrictions can matter if you expect to water landscaping or keep animals.

For neighboring comparisons, begin with Broomfield records that match the intended use and aquifer. Adams County and Boulder County are each about 13 miles away, but proximity alone does not make their wells valid comparisons.

Make water quality, current production and legal supply part of your purchase review. On vacant land, discuss permit eligibility and any applicable augmentation requirements with DWR before committing to construction. Coordinate the well location with septic, drainage, driveway access and the proposed building area.

Well permits by decade near Broomfield County

What a new well costs in Broomfield County

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 (200 ft) would run roughly $16,000–$26,000. 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 Broomfield County? 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 Broomfield County 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.
