Bennett well depth: plan for the Denver Basin

Most Bennett-area wells are completed in the 300-to-600-foot range: that depth mix accounts for 54% of records. Another 25% are under 100 feet, while 11% fall between 100 and 300 feet and 10% are 600 feet or deeper.

The local range is wide. The middle half runs from 90 to 480 feet, the 90th-percentile depth is 592 feet, and the deepest record reaches 2,821 feet. For a driller's bid, use the 360-foot median as a starting point, not a promised completion depth. Denver Basin sedimentary bedrock, the selected aquifer, and the individual lot can all change the final depth.

How much water do Bennett wells produce?

Among Bennett-area permits that report a pump yield, the median is 11.0 gallons per minute. The middle half is tightly grouped between 10.0 and 14.0 gallons per minute. About 76% report yields from 5 to 15 gallons per minute, and 23% 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 ordinary household planning, but a permit yield is not the same as guaranteed long-term production. Ask for the well completion report, pumping information, storage capacity, and the permit's allowed use before relying on a number.

Bennett water levels and the recent trend

Reported static water levels have a median of 158 feet below ground, with the middle half between 90 and 245 feet. A buyer should account for that water level when reviewing pump setting, electrical requirements, and the cost of lifting water to the house.

The decade figures show a deeper reported water level in newer measurements: the median was 130 feet below surface in the 2010s and 180 feet in the 2020s. That difference suggests the measured water level may be lower in the more recent records, but it does not by itself prove a basin-wide decline. Measurements may come from different wells, aquifers, seasons, and testing conditions.

Bennett drilling history and local permit records

Bennett has a long drilling record. Permits were issued from the 1950s through the 2020s, with the newest permit year listed as 2025. The busiest decades in the records were the 1990s, with 353 permits, and the 2000s, with 401. There are 1,758 wells in the Colorado DWR permit records, including 919 recorded as constructed.

The most common drillers in this record are Crandall Drilling & Pump Service, including Crandall Jr. and Howard H., with 357 records; Don Eastwood Drilling Inc., with 138; and Crandall Drlg. & Trenching Inc, with 89. These names help when tracking down older completion details, but the current contractor still needs to evaluate the lot.

What a new Bennett well may cost

The local cost model uses a drilling rate of $50-$70 per foot in Denver Basin sedimentary bedrock. At the 360-foot median depth, the drilled hole works out to about $18,000-$25,200.

A finished system with pump, pressure tank, trenching, and electrical is estimated at $24,000-$37,200. Treat that as a planning range rather than a fixed quote. A deeper-than-typical hole, difficult access, extra casing or grout, a longer trench, or an unexpected completion can move the price. Get the bid in writing and ask what happens if the well reaches a dry or inadequate zone.

Risks to check before buying near Bennett

The permit records identify Denver Basin aquifer wells throughout this area, with permits also naming the Denver and Upper Arapahoe aquifers. The records include 692 wells in an unnamed or fractured-bedrock aquifer, 376 in the Denver aquifer, and 199 in the Upper Arapahoe aquifer. Fractured zones can be less predictable than their nearby neighbors, so location-specific records matter.

Environmental screening also deserves attention. Within about ten miles are 93 PFAS sampling or contamination sites and 27 EPA Superfund or cleanup sites. There are no historic mine features mapped in that search, but that does not replace testing. Test existing water for appropriate contaminants, verify septic setbacks and soil suitability, and confirm that the well location leaves room for the house, septic system, driveway, and future repairs.

A practical lot check for Bennett buyers

Start with the closest completed wells, not just the countywide median. Compare their depths, reported yields, static levels, aquifers, uses, and construction dates. A household well is commonly permitted for exempt domestic use, but the permit controls what the well may legally serve. In an over-appropriated basin, an augmentation plan may be required for some uses or changes.

For a buildable lot, confirm legal access for a large drilling rig, a staging area, power routing, and separation from septic components. Budget from the local finished-well range, then keep room for sitework and treatment. The nearby records for Strasburg, Watkins, Brick Center, Comanche Creek, Byers, and Aetna Estates can provide useful context, but the Bennett lot's own neighboring wells are the better comparison.

What a new well costs in Bennett, 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 (480 ft) would run roughly $30,000–$45,600. 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 Bennett? 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 Bennett 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.
