Sterling, CO Well
Drilling Cost

Sterling well drilling economics are shaped by the South Platte alluvial aquifer, not the Ogallala

Most eastern Colorado well drilling content assumes you’re drilling into the Ogallala Aquifer. Sterling sits at the transition zone — the South Platte River alluvial aquifer dominates the Logan County water table in the northern half of the county, and the Ogallala takes over further south and east. That matters for your quote in three specific ways:

1. Alluvial wells are shallower and cheaper. Sterling residential wells average 180 feet vs 250-300 feet in deeper Ogallala country like Yuma County. That’s real cost savings — roughly $2,000-$4,000 less per well.
2. Water rights are more complex. The South Platte is one of the most-regulated river systems in the country. Non-exempt wells almost always need an augmentation plan (replacement water) to comply with Prior Appropriation rules.
3. Water quality issues are different. Alluvial water tends toward higher nitrate and calcium hardness; deep Ogallala tends toward higher iron and manganese. Test panels should reflect this.

Sterling well cost at a glance (2026)

Sterling residential wells average about $8,900 complete, materially below the Colorado state average of $10,500 driven by shallower alluvial drilling.

What makes Sterling drilling different from other Colorado markets

1. The South Platte alluvial advantage

The South Platte River runs east-northeast through Logan County, and its alluvial aquifer extends 1-8 miles wide along the river valley. Properties within this alluvial band typically hit adequate water at 100-180 feet — half the depth of properties on the uplands south of the river or east near the KS border.

For a residential well, that means:

• 150-foot wells are common (vs 250-350 feet in Ogallala-only areas)
• Cost per foot runs $26-$40 in soft alluvial materials (vs $35-$55 in Ogallala/shale)
• Yield is generally strong — 15-40 GPM typical for a properly-completed residential well

Ask your driller specifically: are we drilling South Platte alluvial or Ogallala? If they don’t know, they’re not familiar with Logan County geology.

2. Colorado Water Division 1 augmentation reality

Sterling is in Colorado’s Water Division 1 (South Platte River basin), which is one of the most tightly-regulated groundwater basins in the state. For any non-exempt well (city of Sterling, most residential subdivisions):

• Augmentation-share membership is required — you pay a water provider to replace the water you consume
• Typical augmentation shares in Logan County: $800-$3,500 upfront for the share, plus $150-$450/year in assessments
• The augmentation cost is NOT usually in your driller’s quote — it’s a separate agreement with a water provider or subdivision water court decree

Before signing a drilling contract in Sterling, verify:

1. Is your parcel in an exempt zone (35+ acres, or unincorporated with specific size rules)?
2. If non-exempt, what augmentation plan applies to your parcel?
3. What are the ongoing augmentation costs?

Check your parcel status at Colorado Division of Water Resources. This can add $2,000-$5,000 to your all-in well cost that no driller will mention.

3. Sterling water quality: what to test for

Sterling-area groundwater has specific concerns different from deep Ogallala:

• Nitrate: Common in alluvial aquifers near agricultural land. Test at completion; retest annually. Elevated nitrate ($40+ ppm) requires RO or ion-exchange treatment.
• Calcium hardness: Typically 200-400 ppm. Requires a water softener for household use ($1,200-$2,500).
• Iron and manganese: Moderate concern. Some Sterling wells need an iron filter ($1,500-$2,800).
• Uranium: Naturally elevated in some Cretaceous sandstone contact zones. Test if drilling below 300 feet.
• Selenium: Regional concern in irrigation-return water; test if property is near active row-crop operations.

Get a comprehensive water panel test 30-45 days after drilling from a state-certified lab. Cost: $150-$350. Highest-ROI $200 you’ll spend on your well.

Sterling area contractors and market

Sterling is served by:

• Newbanks Pumps (Otis, CO — about 40 miles southeast) — actively serves Sterling area for pump installation and well work
• Northeastern Colorado well drilling specialists based in Sterling itself
• Some Wyoming-based drillers extending south during peak season

When comparing quotes:

• Alluvial vs Ogallala experience — different geology, different drilling approach
• Augmentation plan experience — reputable Sterling drillers help homeowners navigate augmentation rather than leave it as your problem
• Turnkey vs itemized pricing — get itemized breakdowns
• DWR reporting — verify your driller files the well construction report with Colorado DWR (required within 60 days of completion)

Real permit costs

Total permitting for a typical Sterling residential well: $275-$500 for exempt wells, $500-$1,000 for non-exempt.

When to drill in Sterling

• Best drilling months: April-October. Ground freeze from mid-November through March limits drilling to specialty crews with heated equipment.
• Get quotes in: January-March for spring drilling, or May-August for fall drilling
• Peak-season contractor availability: April-August contractors are booked 4-8 weeks out
• Total timeline (from initial quote to functional well): typically 8-14 weeks including permit review, drilling, pump installation, and water quality settling

If you’re building or buying property in Logan County with intent to drill, start the well conversation 3-4 months before you need water.
