Rush, Colorado Well Depth, Yield, and Cost Guide

How deep are wells around Rush?

How much water do wells make near Rush?

Rush well depths and the ground below

Rush wells have a median reported depth of 280 feet. The middle half runs from 175 to 360 feet, while the 90th percentile reaches 475 feet. That spread matters when you request a drilling bid: a lot with a 280-foot estimate should not be priced the same as one where nearby wells approach 475 feet.

Depth records are concentrated in the 100-to-300-foot and 300-to-600-foot ranges. The local permits identify 286 wells in unnamed or fractured-bedrock aquifers, with additional wells in Laramie Fox Hills and Pierre Shale. In this Denver Basin sedimentary-bedrock setting, drilling conditions can change across short distances. Neighboring well logs are the best first check, but a driller still has to price for uncertainty, casing, grout, and the final completion depth.

What Rush wells produce

Among the 194 Rush-area wells that report a pump yield, the median is 10.2 gallons per minute. The middle half is 9.2 to 12.0 gallons per minute, and 79% fall between 5 and 15 gallons per minute. Another 14% report more than 15 gallons per minute.

No recorded wells in this set report less than 1 gallon per minute, while 7% report 1 to 5 gallons per minute. That is encouraging for household planning, but a pump test is still more useful than a countywide summary. Ask whether the reported figure is a short test or a sustained production rate, and confirm storage-tank sizing if the home, stock use, or irrigation demand will be significant.

Rush water levels and the recent measurement trend

The median static water level is 202 feet below the ground surface, with the middle half between 134 and 228 feet. That measurement is not the same as total well depth: a 280-foot well may have water substantially above its bottom, and pump placement must account for drawdown and recovery.

The decade medians show 165 feet below surface for measurements in the 2010s and 214 feet for measurements in the 2020s. That pattern suggests deeper measured water levels in the newer decade, but only 60 wells report static water levels, and the wells measured may not be the same wells or aquifers. Treat it as a reason to investigate, not proof of a uniform water-table decline across every Rush property.

Who has drilled around Rush, and when

The permit history shows steady activity over many decades, with the newest permit year in 2025. The records contain 439 permitted wells, including 323 recorded as constructed. Permit counts rose from earlier decades, reached 84 in the 1990s, and include 60 permits in the 2020s.

Kunau Drilling LLC, associated in the records with Timothy R. Kunau, is the most frequent listed driller with 122 wells. Hamacher Well Works Inc., associated with Alan Ray Hamacher, appears on 100. Kunau Drilling & Excavation, associated with Harvey Kunau, appears on 28. These names show local permit history, not a recommendation. For a new project, confirm licensing, insurance, references, construction methods, and who will handle the permit and pump installation.

What a new Rush well may cost

For Rush ground identified as Denver Basin sedimentary bedrock, the drilling rate model is $50 to $70 per foot. At the 280-foot median depth, the drilled hole works out to about $14,000 to $19,600.

A finished well with pump, pressure tank, trenching, and electrical is modeled at about $20,000 to $31,600. That is a planning range, not a guaranteed bid. A deeper hole, difficult access, extra casing or grout, longer utility runs, a larger storage system, or unexpected formation conditions can move the final price. Ask each bidder to separate drilling, casing, grouting, pump equipment, electrical, trenching, testing, and permit-related work so proposals can be compared honestly.

Rush risks to check before building

Five PFAS sampling or contamination sites are mapped within about ten miles of Rush. That does not establish contamination at a particular well, but it is a reason to test existing water and review the location of any environmental site relative to the property. The records show no historic mine features and no EPA Superfund or cleanup sites within that mapped area.

Low-yield and dry-hole risk cannot be ruled out by a median. Confirm the well location, aquifer, construction report, pump test, and static water level before relying on a neighbor's result. Septic setbacks, driveway access, electrical routing, and building envelopes also need to be laid out together. Have the proposed septic system and well locations reviewed before excavation or a house plan is finalized.

A practical plan for buying land near Rush

Start with the DWR permit records for the lot and nearby parcels, then compare total depth, aquifer name, static water level, yield, and use. The local use mix is heavily domestic or household, with stock use also common, so confirm that the existing permit supports the use you intend. Irrigation is uncommon in this record set.

For a vacant lot, get a driller's site review before closing if the well location is uncertain. Budget using the local depth and cost ranges, but keep room for a deeper completion and site work. Colorado permits control what an exempt household-use well can do, including the 35-gallon-per-minute pumping limit, and over-appropriated basins may require an augmentation plan. Verify current rules with DWR and your water attorney.

Well permits by decade near Rush

What a new well costs in Rush, 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 (360 ft) would run roughly $24,000–$37,200. 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 Rush? 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 Rush 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.
