Colorado Well Finder › Wells by county › Adams County › Westminster
Planning a rural purchase or new build near Westminster means looking past the house and checking the well record. The Colorado DWR database shows 4,760 permitted wells within 5 miles, although only 2,263 are recorded as constructed and 181 report a pump yield.
The local numbers are broad because this area includes shallow plains wells, deeper Denver Basin wells, monitoring wells, and different construction purposes. Use the statistics to set expectations, then have a driller review nearby logs, aquifer information, water rights, and the proposed building site before you rely on a well.
Figures are computed from Colorado Division of Water Resources permit records for permitted wells within 5 miles of Westminster. Not every permit reports every field; each statistic uses the wells that report it.

Westminster wells are unusually shallow by the local record: the median reported depth is 27 feet, and the middle half runs from 20 to 65 feet. That does not mean every new well will be shallow. The 90th-percentile depth is 375 feet, and the deepest record reaches 1,751 feet.
About 78% of reported wells are under 100 feet, while 9% fall between 100 and 300 feet, 8% between 300 and 600 feet, and 6% exceed 600 feet. The records name 3,557 wells in an unnamed or fractured-bedrock aquifer, 376 in the Alluvial aquifer, and 100 in the Arapahoe aquifer. A driller should price your lot from nearby construction logs, not from the 27-foot median alone.
Among the 181 wells with a reported pump yield, the median is 10.0 gallons per minute. The middle half produces 5.0 to 15.0 gallons per minute. That is a workable range for many household uses, but the yield test and storage setup matter more than a regional average.
The spread is significant: 12% report under 1 gallon per minute, 9% report 1 to 5 gallons per minute, 45% report 5 to 15 gallons per minute, and 34% report more than 15 gallons per minute. A low-yield well may still serve a home with adequate tank storage, while a buyer should not assume that a nearby high-yield record will repeat on another lot. Confirm the permitted use and test the actual well.
The reported static water level has a median depth of 16 feet below the surface, with the middle half between 10 and 39 feet. Those measurements are useful for planning pump depth and construction, but static level is not the same as sustainable pumping capacity. It can change with season, nearby pumping, recharge, and the time since the well stopped pumping.
The decade series does not show a simple dropping water table in these records. Median depth to water was 32 feet in the 1960s, 25 feet in the 2010s, and 12 feet in the 2020s. That pattern may reflect different wells, locations, uses, and measurement conditions rather than a basin-wide rise. Have a professional compare nearby wells with similar construction before drawing a conclusion about your lot.
The permit history is active and heavily weighted toward later decades. Records show 129 permits from the 1950s, 80 from the 1960s, 175 from the 1970s, 195 from the 1980s, 890 from the 1990s, 1,040 from the 2000s, 779 from the 2010s, and 446 from the 2020s. The newest permit year is 2025.
In the available records, Authorized (Pe, Pg) appears most often, with 1,801 records. Ground Exploration LLC (Bender, Joseph T.) appears on 91, and High Plains Drilling (Jecminek, Charles L.) on 83. Those counts describe permit records, not current availability or a recommendation. Many listed wells are monitoring wells: 61% are monitoring, compared with 21% domestic or household, 2% irrigation, and 1% stock.
The cost model for Westminster ground uses Denver Basin sedimentary bedrock and a typical drilling rate of $50 to $70 per foot. At the 27-foot median depth, the drilled hole is modeled at about $1,400 to $1,900. A finished system, including the pump, pressure tank, trenching, and electrical, is modeled at about $7,400 to $13,900.
That estimate is a starting point, not a fixed bid. The large range in recorded depths means the median may not fit a particular parcel, especially where the target aquifer or construction conditions call for a deeper hole. Ask for separate line items for drilling, casing and grout, pump equipment, trenching, electrical work, testing, and any permit or water-rights requirements. Confirm what happens if the hole is dry or produces less than expected.
Low yield and dry-hole risk deserve attention even though the reported yield median is 10.0 gallons per minute. Only 181 records report a pump yield, so the yield statistics are not a complete survey of all 4,760 permits. Fractured-bedrock conditions can be unpredictable, and a nearby well is evidence to investigate rather than a guarantee.
Environmental screening also matters. The mapped area within about 10 miles includes 570 PFAS sampling or contamination sites, 76 EPA Superfund or cleanup sites, and 75 historic mine features. That does not prove contamination at a property. Test existing water for the conditions relevant to the site, inspect casing and grout, and confirm septic setbacks, drainfield space, access for drilling equipment, and the building location before closing or excavating. A Colorado DWR permit and an exempt household-use well are not the same as unlimited water rights; over-appropriated basins may require an augmentation plan.
Start with the exact parcel and nearby areas such as Shaw Heights, Federal Heights, Sherrelwood, Northglenn, Twin Lakes, and Broomfield. Pull the DWR permit, construction report, pump test, static water level, use designation, and aquifer information for neighboring wells. Separate domestic records from monitoring wells before using them to estimate what your home may receive.
For a purchase, make well inspection, water testing, flow testing, and legal water-use review part of the contract process. For a new build, locate the well and septic system together so access, setbacks, electrical service, and the drainfield work with the house plan. A driller can use the 20-to-65-foot middle range as an initial reference, but the wide depth records justify a site-specific bid and a contingency for a deeper or lower-yield result.

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 (65 ft) would run roughly $9,250–$16,550. See the full Colorado well cost guide.
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.

A listing photo can't tell you whether a lot is a dream or a money pit. Two parcels near Westminster 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.
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.

The median reported well depth within 5 miles of Westminster is 27 feet, with the middle half between 20 and 65 feet. Most reported wells, 78%, are under 100 feet. Depths vary considerably, however: the 90th percentile is 375 feet and the deepest record is 1,751 feet. Nearby construction logs are more useful than the median for pricing a specific lot.
The local cost model uses $50 to $70 per foot. At the 27-foot median depth, the drilled hole is estimated at about $1,400 to $1,900. A completed system with pump, tank, trenching, and electrical is estimated at $7,400 to $13,900. A deeper hole, difficult access, different casing needs, or a dry or low-yield result can change the bid.
Reported yields have a 10.0-gallon-per-minute median, with the middle half from 5.0 to 15.0 gallons per minute. Results are not uniform: 12% of reported yields are under 1 gallon per minute, while 34% exceed 15 gallons per minute. Only 181 wells report a pump yield, so request a test of the actual well and review available storage.
Safety cannot be determined from location or a permit record alone. Within about 10 miles, the mapped area includes 570 PFAS sampling or contamination sites, 76 EPA Superfund or cleanup sites, and 75 historic mine features. Those locations do not establish contamination on a particular parcel. Test the well water, inspect construction, and use a qualified laboratory and water professional to interpret results.
Yes. Review the DWR permit and construction report, then verify the well's use, aquifer, static level, yield, casing, grout, and pump condition. The area includes many monitoring wells, so do not treat every nearby record as a household comparison. Also confirm septic space, access for a drill rig, building setbacks, and whether water-use rules or an augmentation plan affect the proposed home.
