What Mosca Wells Cost, Produce, and Require

How deep are wells around Mosca?

How much water do wells make near Mosca?

Mosca well depth depends on the local ground

Mosca wells are commonly shallow in the available records. 66% are under 100 feet, while 26% fall between 100 and 300 feet. The middle half of reported depths, from 60 to 108 feet, is the most useful range for an initial drilling conversation.

Still, the record includes wells as deep as 2,563 feet, with 4% deeper than 600 feet. That spread means a median-depth estimate is not a promise. Mixed sedimentary and alluvial ground can change from one parcel to the next, and some permits identify unnamed or fractured-bedrock aquifers. A driller should review nearby logs, access, casing and grout requirements before giving a firm bid.

Reported Mosca yields are strong, but verify the test

Among the 352 wells reporting a pump yield, the median is 300.0 gallons per minute, with the middle half from 15.0 to 500.0 gallons per minute. The record shows 86% above 15 gallons per minute, 14% from 5 to 15 gallons per minute, and 1% under 1 gallon per minute.

Those figures are not a guaranteed household supply. Many records are irrigation wells, and a pump-yield entry may not match a sustained household test. Ask for the well completion report and pumping information for the specific parcel. An exempt household-use well is generally limited to 35 gallons per minute under Colorado rules, so a high-yield irrigation record should not be treated as the allowable household pumping rate.

Mosca water levels look shallow without a clear decline

Only 93 records report a static water level, so the water-level sample is much smaller than the depth sample. The median static level is 12 feet below ground, with the middle half between 10 and 14 feet. That is a shallow measured water level, but it is not the same as total well depth.

Measurements by decade were 12 feet in the 1980s, 14 feet in the 2010s, and 13 feet in the 2020s. This series does not show a consistent dropping water table. Seasonal conditions, pumping, measurement method, and the small number of reported levels still matter. Have current water levels checked when evaluating a property, especially if irrigation wells operate nearby.

Mosca has a long permit history and several drillers

Permitting in the Mosca area extends from the 1950s through the newest permit year, 2025. The busiest period in these records was the 1970s, with 292 permits, followed by the 1990s with 264. There were 130 permits in the 2020s so far, so recent activity is still present.

The most active listed drillers are Rocky Mountain Waterworks Llc (Phythian, Donald L.) with 97 records, Biggs And Freel (Biggs, Elmer E) with 93, and Nwp Drlg & Consul (Newmyer, Halsey R.) with 67. These names describe permit history, not a recommendation. Confirm current licensing, availability, and whether a contractor will handle the pump, electrical, trenching, and paperwork.

A typical Mosca well starts near $10,000 finished

For Mosca’s mixed sedimentary and alluvial ground, the drilling model uses approximately $50 to $75 per foot. At the local median depth of 80 feet, the drilled hole is estimated at about $4,000 to $6,000. That is only the hole, not the complete water system.

A finished well with pump, pressure tank, trenching, and electrical is modeled at approximately $10,000 to $18,000. The final price can move outside that range if the site requires unusual casing or grout, difficult access, extra trenching, treatment, or a deeper-than-typical hole. Get a written scope that separates drilling from pump installation and site work, and ask what happens if the first hole has inadequate production.

Check water quality, dry-hole risk, and the building site

Low yield is uncommon in the reported sample, but it is not impossible. A small portion of wells report less than 1 gallon per minute, and many wells have no yield entry at all. A buyer should also understand that permit records do not prove water quality. Within about 10 miles are 1 PFAS sampling or contamination site and 1 EPA Superfund or cleanup site. There are 0 historic mine features mapped in that area.

Test an existing well for the intended household use and ask about septic setbacks, well access, flood or drainage conditions, and space for a replacement system. Confirm the DWR permit and permitted use before building. Irrigation, stock, and domestic permits do not automatically provide the same rights or flexibility.

Use nearby records before buying a Mosca lot

Start with wells closest to the parcel, then expand the comparison toward Hooper, Alamosa East, Alamosa, Center, Monte Vista, and Blanca when the local geology and aquifer information are comparable. Look for reported depth, construction details, static level, yield, and permitted use rather than relying on a single neighbor’s experience.

For a new build, make the well location, septic layout, driveway access, electrical route, and house site work together. In an over-appropriated basin, an augmentation plan may be required for some uses. Have the DWR permit reviewed before closing, obtain a drilling estimate based on the actual parcel, and reserve money for a pump system and testing beyond the drilling price.

What a new well costs in Mosca, 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 (108 ft) would run roughly $11,400–$20,100. 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 Mosca? 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 Mosca 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.
