Niwot, Colorado Well Depth, Yield, and Drilling Costs

How deep are wells around Niwot?

How much water do wells make near Niwot?

Niwot well depth: shallow records, deeper exceptions

The local depth median is 30 feet, and the middle half of reported wells falls between 16 and 60 feet. That is a shallow profile compared with many mountain properties. Still, the depth range is wide: 80% of wells are under 100 feet, 14% are between 100 and 300 feet, and 6% are between 300 and 600 feet. The deepest record reaches 3,000 feet.

For a bid, the median is only a starting point. Fractured granite and gneiss can change the required depth quickly when a borehole does not encounter a productive fracture. Look at nearby wells in the same geologic setting, not just the closest address. Records from Gunbarrel, Leyner, and Valmont can help provide local comparison, but they do not replace a site assessment.

How much water Niwot wells produce

Reported well yield has a 10.0 gallons-per-minute median, with the middle half between 5.0 and 15.0 gallons per minute. The largest group, 60%, reports yields from 5 to 15 gallons per minute, while 25% report more than 15 gallons per minute.

Low-producing wells are less common but important: 3% report under 1 gallon per minute, and 12% fall between 1 and 5 gallons per minute. A buyer should not treat the median as a guarantee. Ask for the well test, pump size, storage capacity, and recovery information. Household-use exempt wells generally have a 35-gallon-per-minute pumping limit, and water use still has to match the permit.

Niwot water levels and what the records can tell you

Only 80 wells in the records report a static water level, so this part of the dataset is much thinner than the depth data. Among those reports, the median depth to water is 9 feet, with the middle half between 7 and 13 feet. That suggests shallow water levels in the reported wells, but it is not enough to establish a reliable trend across every neighborhood or aquifer.

The permits identify 1,895 wells in an unnamed or fractured-bedrock aquifer and 111 in alluvial material. They also identify 26 in the Laramie Fox Hills aquifer, while Denver Basin aquifer wells account for 28%. Confirm the aquifer and current water level for the specific parcel before relying on a neighboring measurement.

Niwot permit history and the drilling records

Niwot-area permit activity stretches from the 1950s through the newest permit year, 2025. The records show 48 permits in the 1950s, 67 in the 1960s, 259 in the 1970s, 193 in the 1980s, and 335 in the 1990s. There were 319 in the 2000s, 278 in the 2010s, and 234 in the 2020s.

The most frequent driller names in these records are Authorized (Pe, Pg), with 497 records, followed by Waneka & Son Drilling with 88 and Ground Water Systems Inc with 74. A permit record is not the same as a current inspection or performance guarantee, so verify construction, testing, and ownership documents.

What a new Niwot well may cost

The cost model for Niwot assumes fractured mountain bedrock, including granite and gneiss. Drilling is modeled at $65 to $100 per foot. At the local 30-foot median depth, the drilled hole alone works out to about $2,000 to $3,000.

That is not the complete project price. A finished well with a pump, pressure tank, trenching, and electrical work is modeled at about $8,000 to $15,000. A deeper hole, difficult access, casing and grout requirements, or a low-yield result can change the bid. Have the contractor separate drilling, casing, pump equipment, electrical, trenching, testing, and any failed-hole provisions so you can compare bids accurately.

Niwot risks to check before buying or building

Water quality deserves a parcel-specific review. Within about 10 miles, the map shows 470 PFAS sampling or contamination sites, 115 historic mine features, and 17 EPA Superfund or cleanup sites. Those mapped sites do not prove contamination at your property, but they are a reason to test the well water and review nearby land uses, direction of groundwater flow, and the well's construction.

Also check for low yield, dry-hole history, damaged casing or grout, and adequate separation between the well and septic system. A new home may require an augmentation plan in an over-appropriated basin. Confirm the permit's allowed use, domestic limits, septic feasibility, driveway access, and building envelope before buying land or starting design.

Well permits by decade near Niwot

What a new well costs in Niwot, 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 (60 ft) would run roughly $9,900–$18,000. 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 Niwot? 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 Niwot 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.
