What Parker Well Records Tell You Before You Buy

How deep are wells around Parker?

How much water do wells make near Parker?

Parker well depths run deeper than many buyers expect

The median permitted well near Parker is 320 feet deep. The middle half runs from 210 to 485 feet, so a bid based only on the median can miss the conditions at a particular lot. The 90th percentile is 646 feet, and the deepest recorded well reaches 2,745 feet.

Depth records are concentrated in the middle range: 41% are between 300 and 600 feet, while 28% fall between 100 and 300 feet. Fifteen percent are under 100 feet, and another 15% exceed 600 feet. The aquifers named most often are the Lower Dawson, Upper Dawson, and unnamed fractured-bedrock aquifer.

For a driller's proposal, ask what depth assumption is included, when extra footage is billed, and how casing and grout will be handled.

Most Parker wells make enough for a home, but verify the test

Among nearby records that report a pump yield, the median is 14.0 gallons per minute. The middle half is 12.0 to 15.0 gallons per minute. Fifty-six percent report yields from 5 to 15 gallons per minute, and 44% report more than 15 gallons per minute.

No reported wells fall under 1 gallon per minute or between 1 and 5 gallons per minute in this dataset. That is encouraging for a normal household, but it is not a guarantee for an unbuilt lot. A yield test is a snapshot, and storage capacity, pump sizing, household demand, and permit conditions still matter.

Ask for the well construction report, pump test, and current production information. A domestic or household-use permit may have limits, and an exempt household-use well is not the same as an unlimited irrigation source.

Parker water levels vary, so the decade record needs context

The median reported static water level is 195 feet below the surface, with the middle half from 100 to 395 feet. That range affects pump setting, electrical planning, and the cost of getting water from the wellhead to the house.

The decade medians do not form a steady downward pattern. Reported depth to water was 114 feet in the 1970s, 230 feet in the 1980s, 441 feet in the 2000s, 285 feet in the 2010s, and 160 feet in the 2020s. Different wells, locations, aquifers, and measurement conditions can drive that variation.

Do not treat the series as proof that Parker's water table is simply dropping or recovering. Get the static level for the subject well and have the pump contractor size equipment around actual conditions.

Parker's permit history shows long local drilling experience

DWR records include 4,842 permitted wells within five miles of Parker, with 2,613 recorded as constructed. The permits span several decades, and the newest permit year is 2025. The largest permit totals are from the 1970s and 1980s, with 877 and 947 permits respectively.

The most active drillers in these records are Hier Drilling Co Inc (Hier, Bruce A.), Hier Drilling Co. (Hier, Peter J), and Parker Drilling/Pump Service Inc. (Thrasher, Tommy E.). Those names identify local permit history, not a recommendation or a guarantee of current availability.

Before hiring anyone, confirm licensing, insurance, schedule, casing and grout specifications, pump-test terms, and who handles the DWR paperwork. A driller should also explain how the estimate changes if the hole must go deeper.

A median-depth Parker well can cost $22,000 to $34,400 finished

In Parker's Denver Basin sedimentary bedrock, the drilling model uses $50 to $70 per foot. At the 320-foot median depth, the drilled hole alone is estimated at about $16,000 to $22,400.

A finished system, including the pump, pressure tank, trenching, and electrical work, is estimated at about $22,000 to $34,400 at that median depth. This is a planning range, not a fixed bid. A well near the deep end of the local range can add substantial drilling cost before the pump and site work are included.

Request a written proposal that separates footage, casing, grout, well development, pump equipment, trenching, electrical, permits, and water testing. Also ask what happens if the hole is dry or produces less than the target yield. Those terms matter as much as the per-foot rate.

Check water quality, low-yield risk, and the building site

Mapped environmental records within about ten miles include 77 PFAS sampling or contamination sites, 7 historic mine features, and 4 EPA Superfund or cleanup sites. These mapped sites do not establish contamination in a particular well, but they are a reason to review site history, well location, groundwater flow, and laboratory testing before relying on the water.

Low yield and dry holes remain practical risks, especially where fractured bedrock controls production. Test the existing well for bacteria, nitrate, and locally relevant contaminants, and ask a qualified professional whether PFAS or other testing is appropriate.

Confirm septic setbacks, reserve area, driveway access, electrical routing, and the buildable envelope before closing. Water rights also matter: augmentation plans may be required in over-appropriated basins, and the permit's allowed use controls what the well can legally serve.

Use neighboring wells to plan a Parker lot

For an existing home, start with the actual well permit, construction report, pump information, production history, and a recent water-quality test. Compare those records with nearby wells in Stonegate, Stepping Stone, Sierra Ridge, Meridian Village, Grand View Estates, and The Pinery when the locations are relevant to the property. Neighboring records can reveal likely depth and aquifer conditions, but they cannot replace a site-specific inspection.

For vacant land, make the well plan part of due diligence. Confirm the permit pathway with Colorado DWR, identify the legal use, reserve room for the well and septic system, and price access for a drilling rig. Carry a budget that recognizes the local depth spread rather than assuming every hole will match the median.

Before you build, have the driller, septic designer, electrician, and excavator coordinate the wellhead, tank, trench, driveway, and house location.

Well permits by decade near Parker

What a new well costs in Parker, 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 (485 ft) would run roughly $30,250–$45,950. 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 Parker? 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 Parker 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.
