What Delta, Colorado Wells Are Really Like

How deep are wells around Delta?

How much water do wells make near Delta?

Delta well depth: shallow is common, but not guaranteed

The median reported well depth near Delta is 37 feet. The middle half runs from 21 to 52 feet, and 94% of the recorded wells are under 100 feet. That is a favorable starting point when asking for a drilling bid in the Delta area, including toward Orchard City and Olathe.

There are exceptions. The deepest recorded well is 470 feet, while 4% fall between 100 and 300 feet and 2% between 300 and 600 feet. A driller should price the actual ground at your lot, not simply use the local median. Permits most often name an unnamed or fractured-bedrock aquifer, with 478 wells in that category. Sedimentary and alluvial conditions can still change quickly from one parcel to the next.

Reported Delta well yields are usually useful for homes

Among the 48 wells that report a pump yield, the median is 15.0 gallons per minute. The middle half is 14.8 to 21.2 gallons per minute, and 75% report more than 15 gallons per minute. Only 2% are under 1 gallon per minute, with another 2% between 1 and 5 gallons per minute.

Those figures suggest that a typical reported well can support ordinary household use, but yield is not the same as storage or guaranteed daily supply. Ask for the well construction report, pump test and production history. An exempt household-use well is generally subject to Colorado’s 35 gallon-per-minute pumping limit. Irrigation, livestock and other uses may require different permit terms or an augmentation plan.

Delta water levels are shallow, but the trend is unclear

The 18 records reporting a static water level show a median depth to water of 7 feet, with the middle half from 6 to 9 feet. That shallow water level can reduce drilling depth, but it also deserves attention during excavation, trenching and basement planning. Water levels can vary with season, pumping and local conditions.

Permit activity spans the 1950s through the 2020s, with the newest permit issued in 2024. That permit history does not establish a falling or rising water table because the available static-water-level records are limited and are not presented as a consistent time series. Have the current owner document water level and pump performance rather than relying only on the local median.

Who has drilled around Delta, and what the permit history shows

Recorded drilling activity has continued across several decades. The largest decade totals are 89 permits in the 1990s, 87 in the 2000s, 67 in the 1970s, 48 in the 1980s, 46 in the 2010s and 21 in the 2020s. These figures describe permits in the five-mile search area, not necessarily completed or currently operating wells.

The most active named driller in the records is K. W. Anderson Drilling, listed as Anderson, Kermit W, with 54 records. Authorized, listed as Pe, Pg, has 52, and Bill Kissner Drilling Inc, listed as Kissner, Bill F., has 26. Treat those names as historical permit information, not a recommendation. Confirm current licensing, availability, scope and references before hiring anyone.

A Delta well may cost less to drill than to finish

For the mixed sedimentary and alluvial ground reported around Delta, the drilling rate model is $50 to $75 per foot. At the local median depth of 37 feet, the drilled hole works out to about $1,800 to $2,800. That is only the hole, not a working water system.

A finished well with pump, pressure tank, trenching and electrical is modeled at $7,800 to $14,800 at the median depth. The final bid can change with access, casing and grout requirements, pump size, trench length, power service and site conditions. Ask the driller to separate drilling, casing, development, pump equipment, electrical and testing so an apparently low bid does not leave out necessary work.

Delta risks to check before buying or building

Low yield is not the only concern. Records show 18 PFAS sampling or contamination sites, 22 historic mine features and 2 EPA Superfund or cleanup sites within about 10 miles. That does not prove a particular well is affected, but it is enough reason to test the water and investigate the property’s direction from known sites. A certified laboratory can test for common household concerns and site-specific contaminants.

Also verify the well permit, construction report, casing and grout details, pump equipment, pressure tank and recent service history. A shallow water level may complicate septic and foundation work if excavation reaches groundwater. Check septic setbacks, replacement-area requirements, drainage, access for a drilling rig and the proposed building location before finalizing plans.

What to do before buying a Delta lot

Start with the exact parcel, then compare nearby permitted wells rather than relying on the town-wide median. Records from Orchard City, Olathe, Cedaredge, Lazear, Hotchkiss and Montrose can provide broader regional context, but the closest wells are usually more useful for estimating depth, aquifer behavior and construction conditions.

For an existing home, make the purchase contingent on reviewing the permit, testing the water and checking pump output under use. For vacant land, have a driller review access, likely well location, septic layout and power route before you set a house plan. Confirm whether the intended domestic, stock or irrigation use is allowed. If the basin is over-appropriated, ask Colorado DWR or a water attorney whether an augmentation plan is required.

Well permits by decade near Delta

What a new well costs in Delta, 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 (52 ft) would run roughly $8,600–$15,900. 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 Delta? 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 Delta 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.
