Rollinsville Colorado Well Depths, Yields, and Costs

Rollinsville well depth: plan for fractured mountain rock

The median well depth around Rollinsville is 220 feet. The middle half runs from 120 to 352 feet, so a driller’s bid based only on the median may not cover the conditions on your lot. One well in the records reaches 1,202 feet, and 4% are deeper than 600 feet.

Depths vary because the local permits primarily identify unnamed or fractured-bedrock aquifers. The records include 3,138 wells in that category, along with 30 in Fractured Crystalline and 15 in Fractured Granite. For budgeting, ask the driller to show the per-foot rate, the assumed drilling depth, and what happens if the hole must continue.

Nearby records from Nederland, Bonanza Mountain Estates, Eldora, and St. Ann Highlands can help establish local context, but the closest comparable wells are the most useful.

What Rollinsville wells produce

Among wells reporting pump yield, the median is 7.0 gallons per minute. The middle half produces 4.0 to 10.0 gallons per minute. A large share, 64%, falls between 5 and 15 gallons per minute, while 25% produce between 1 and 5 gallons per minute.

Only 2% report less than 1 gallon per minute, but that small percentage matters when you are comparing individual properties. A lower-yield well may still work with adequate storage and a properly designed pump system, but it can affect household use and recovery between uses. The records show 8% above 15 gallons per minute.

Most permits are for domestic or household use, accounting for 94% of the records. Confirm the permitted use and pumping limits before assuming the well can support irrigation or other demands.

Water levels around Rollinsville and what the record shows

Reported static water levels have a median depth of 40 feet below the surface, with the middle half between 20 and 61 feet. That is the water level while the well is at rest, not the pumping level. A contractor still needs to evaluate drawdown, recovery, pump setting, and storage.

The decade series does not show a simple, steadily dropping water table. Median reported depth to water was 32 feet in the 1960s, 25 feet in the 1970s, 50 feet in the 2010s, and 40 feet in the 2020s. Measurements are available from only 188 wells, and the wells measured in each period may not represent the same locations.

Use the nearby measurements as clues, not a guarantee. A well close to your lot, in similar ground and at a similar elevation, is more informative than a regional average.

Who drilled near Rollinsville, and when

Permit activity spans several generations. The records show 38 permits from the 1950s, 197 from the 1960s, 584 from the 1970s, 393 from the 1980s, 666 from the 1990s, 448 from the 2000s, 237 from the 2010s, and 148 from the 2020s. The newest permit year is 2025.

The most frequently represented drillers are Ground Water Systems Inc (Wilson, Richard R.) with 573 records, C. R. Smith Drilling (Smith, Calvin R.) with 478, and C R Smith Drilling Inc (Smith, Frank) with 450. A permit listing shows historical activity, not a recommendation or a guarantee that a company is currently available.

When reviewing a property, pull the original permit and construction record. Compare the listed depth, casing, grout, pump yield, and static water level with the seller’s description.

Rollinsville well drilling cost at the median depth

Rollinsville drilling is priced around fractured mountain bedrock, including granite and gneiss. The typical drilling rate used for this area is $65 to $100 per foot. At the 220-foot median depth, the drilled hole estimates to about $14,300 to $22,000.

A finished system with the pump, pressure tank, trenching, and electrical is estimated at about $20,300 to $34,000 at that median depth. This is a planning range, not a fixed bid. A deeper hole, difficult access, casing or grouting requirements, pump changes, or additional trenching can move the final price.

Request an itemized proposal before building your budget. It should separate drilling, casing, grout, development, pump equipment, storage, trenching, electrical work, testing, and permit-related services so you can compare bids accurately.

Risks to check before buying or building

Fractured rock can produce a good well on one parcel and a poor result nearby. Review the 3,253 wells in the local permit scope, paying particular attention to the 1,045 that report pump yield and the 188 that report static water level. A dry hole or low-yield result is not ruled out by a strong median.

Water quality also deserves its own investigation. Within about 10 miles, the map includes 17 PFAS sampling or contamination sites, 2,446 historic mine features, and 11 EPA Superfund or cleanup sites. Those mapped features do not prove contamination at your property. Test the actual well, and discuss appropriate testing with a qualified water professional.

Check septic setbacks, replacement-area options, slope, access for a drill rig, and the proposed building location. A well and septic system need to work together with the house site.

A practical Rollinsville lot-buying plan

Start with the Colorado DWR permit record for the property and nearby parcels. Compare depths, yields, static levels, construction details, and permitted uses. Look first at wells near the lot, then expand toward Coal Creek and Black Hawk only when you need more context.

For an existing home, obtain a recent flow or yield evaluation, static and pumping water levels, and a laboratory water test. For vacant land, have a driller review access, geology, likely depth, and the location of the house and septic system before you make a final site plan.

Remember that an exempt household-use well has a 35-gpm pumping limit, and over-appropriated basins may require an augmentation plan. Confirm the actual water right and allowed uses with Colorado DWR. Good records reduce surprises, but they cannot guarantee the result on a new hole.

What a new well costs in Rollinsville, 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 (352 ft) would run roughly $28,880–$47,200. See the full Colorado well cost guide.

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 Rollinsville? 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 Rollinsville 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.
