Ellicott, Colorado Well Depth, Yield, and Cost

How deep are wells around Ellicott?

How much water do wells make near Ellicott?

Ellicott well depths and the Denver Basin ground

Ellicott wells have a median reported depth of 160 feet. The middle half runs from 115 to 355 feet, so a driller bidding a new well should not treat the median as a fixed target. Most recorded wells, 58%, fall between 100 and 300 feet. Another 18% are between 300 and 600 feet, while 8% exceed 600 feet. The deepest record reaches 1,110 feet.

The ground is described in the cost model as Denver Basin sedimentary bedrock. Permits identify Denver Basin aquifer wells throughout this area, with 686 wells associated with unnamed or fractured-bedrock aquifers, 228 with the Arapahoe, and 211 with Quaternary Alluvium. Nearby results in Yoder, Falcon, Peyton, or other surrounding areas can provide context, but the closest wells to your lot matter most.

What an Ellicott well is likely to produce

Reported well yield is strong in this record, with a median of 11.7 gallons per minute and a middle half from 10.0 to 14.1 gallons per minute. Seventy-two percent of wells reporting yield fall between 5 and 15 gallons per minute, and 25% report more than 15 gallons per minute. Only 3% report between 1 and 5 gallons per minute, and none report under 1 gallon per minute.

That does not mean every new hole will match the median. Only 384 wells report a pump yield, compared with 1,468 permitted wells overall. Ask for the neighboring well completion reports, pumping information, and any production test. A good yield still needs suitable storage, pump sizing, and water quality for the home you plan to build.

Ellicott water levels and the record over time

Among 113 wells reporting static water level, the median depth to water is 123 feet. The middle half is 81 to 198 feet below the surface. That depth affects casing, pump setting, electrical work, and the amount of trenching or equipment needed during construction.

The decade medians show deeper reported water levels over time: 28 feet in the 1950s, 65 feet in the 1960s, 145 feet in the 2010s, and 170 feet in the 2020s. This pattern suggests water was measured deeper in the more recent records, but it is not proof of a uniform decline. The wells, locations, aquifers, and measurement conditions may differ. A buyer should obtain the current static level and pumping information for the specific well rather than rely only on the historical series.

Who has drilled around Ellicott, and when

Permit activity spans the area’s older rural development through current construction. Records show 36 permits from the 1950s, 79 from the 1960s, 124 from the 1970s, 239 from the 1980s, 200 from the 1990s, 233 from the 2000s, 98 from the 2010s, and 95 from the 2020s. The newest permit year in the record is 2025.

The most active listed drillers are Kunau Drilling LLC, with 256 records; M & B Drilling Co., with 207; and Hamacher Well Works Inc., with 171. Those counts describe permit records, not a guarantee of current availability or workmanship. Confirm licensing, insurance, scheduling, casing and grout specifications, testing, and exactly what the bid includes before selecting a contractor.

What a new Ellicott well may cost

The local drilling model uses a rate of $50 to $70 per foot for the Denver Basin sedimentary bedrock. At the 160-foot median depth, the drilled hole works out to about $8,000 to $11,200. A finished system with pump, tank, trenching, and electrical is estimated at $14,000 to $23,200.

Use the 115-to-355-foot middle-half depth range when comparing bids. A price based only on the median may be too low for a parcel that resembles the deeper nearby wells. Get a written allowance for mobilization, casing, grout, development, water testing, disposal, and difficult access. Confirm whether the quoted number covers only drilling or the complete usable water system.

Ellicott risks: water quality, dry holes, and septic layout

Low yield is not the main warning in the reported results, but incomplete reporting means the record cannot eliminate dry-hole or poor-production risk at a particular lot. Fractured-bedrock conditions can be unpredictable, and a nearby successful well does not guarantee the same result. Require a clear drilling and testing plan before work begins.

Environmental review also matters. Within about ten miles, the map shows 7 PFAS sampling or contamination sites and 34 EPA Superfund or cleanup sites. That does not establish contamination at your property, but it supports testing the finished well for the contaminants relevant to the site and its land use. Keep the well, septic system, leach field, drive, and house location coordinated. Confirm El Paso County and state setbacks, septic approval, and the permit’s allowed household, stock, or irrigation use.

A practical Ellicott lot-buying and building check

Start with the closest permitted wells, not a countywide average. Review their depths, aquifers, static levels, yields, construction details, and use. The local permit mix is 67% domestic or household, 29% stock, 19% irrigation, and 4% monitoring, so confirm that a neighboring record is comparable to the home you want.

Before closing, make the well permit and completion record part of the inspection file. Test the existing water, verify pump performance, locate the septic system, and ask an experienced driller to price a replacement or new well using nearby depths. If you are building, confirm access for the rig and delivery equipment, then coordinate well, septic, driveway, utilities, and the house pad. In an over-appropriated basin, ask the water attorney or county about augmentation and the permitted use before assuming a domestic well solves every water need.

Buying land near Ellicott? 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 Ellicott 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.
