Utilities & Off-Grid

Overview

The Wyoming parcel is off-grid — there are no public utilities (electricity, water, sewer, natural gas, or landline telephone) running to the property. Any development will require installing independent systems. This page summarizes the options for each utility, the typical costs, and the regulatory considerations.

For most Sweetwater County rural landowners, off-grid living is the standard. Solar power, well water, septic systems, and satellite internet are the typical solution. This approach offers energy independence, freedom from monthly utility bills, and resilience to grid outages.

Electricity

Grid Power

• Availability: No grid power runs to the property
• Nearest power line: Approximately 0.5-2 miles from the property boundary (verify with Rocky Mountain Power)
• Cost to extend grid: Typically $20,000–$50,000+ per mile, depending on terrain, distance, and required easements
• Service provider: Rocky Mountain Power (PacifiCorp territory)

Off-Grid Solar

• System size: 5kW–10kW typical for a modest cabin or home
• Annual production: 7,500–15,000 kWh (Sweetwater County is one of the sunniest places in the US)
• Battery storage: 20–40 kWh lithium-ion (Tesla Powerwall, Enphase, or similar)
• Generator backup: Propane or diesel generator recommended for winter and cloudy periods
• Estimated system cost: $25,000–$50,000 for a complete turnkey installation
• Incentives: Federal Investment Tax Credit (ITC) currently provides 30% credit for residential solar installations through 2032

Wind Power

• Small wind turbines: Viable in Sweetwater County's persistent winds
• Cost: $5,000–$20,000 for a residential-scale turbine
• Combined solar + wind: Common configuration for off-grid reliability

Water

Well Water

• Aquifer: The property is in the Greater Green River Basin, with varying aquifer depths
• Typical well depth: 50–300 feet, depending on location
• Water quality: Generally good — moderately hard water with some mineral content
• Estimated well cost: $15,000–$35,000 for drilling, pump, pressure tank, and controls
• Permits required: Wyoming State Engineer's Office well permit
• Water rights: For any use beyond stock watering, a water right is required from the Wyoming State Board of Control

Rainwater Harvesting

• Annual rainfall equivalent: 8–12 inches (most falls as snow)
• Roof catchment: Common for cabin use, sized to a 1,500–5,000 gallon cistern
• Snowmelt collection: Viable in spring
• Legal status: Wyoming allows rainwater harvesting for non-stock use without a water right (verify current law)

Water Hauling

• Cost: $0.10–$0.20 per gallon delivered in the area
• Tank size: 1,000–3,000 gallon tanks common for hauled water
• Truck access: Required year-round

Surface Water

• None on the property — there are no permanent streams, ponds, or springs on the parcel
• Nearest surface water: Green River, approximately 15 miles south
• Riparian areas: Not present on the property

Sewer

Septic System

• Required for: Any permanent structure with indoor plumbing
• System type: Conventional septic tank + drainfield, or aerobic treatment unit (ATU) for poor soil conditions
• Permits: Sweetwater County Department of Environmental Health
• Soil test: Percolation test required prior to design and installation
• Cost: $8,000–$20,000 for a conventional residential system
• Maintenance: Tank pumping every 3–5 years

Composting Toilet

• Viable alternative: For cabins used part-time
• No permits required in most cases (verify with county)
• Cost: $1,000–$3,000 installed
• Maintenance: Periodic emptying of compost

Greywater

• Allowed: For subsurface irrigation of landscaping
• Permits: Sweetwater County greywater disposal regulations apply

Heating & Cooling

Propane

• Source: Local propane companies in Rock Springs
• Delivery: Scheduled bulk delivery to on-site tank (typically 500–1,000 gallon)
• Cost: $2.50–$3.50 per gallon (varies seasonally)
• Tank ownership: Lease ($50–$100/year) or purchase ($2,000–$4,000)
• Uses: Cooking, water heating, space heating (propane furnace or stove), clothes drying, generator backup

Wood Heat

• Viable in Sweetwater County — juniper and pine available on and near the property (with proper permits)
• Cost: Low — labor for cutting and splitting; some property owners harvest their own
• Permits: May be required for commercial-scale cutting on BLM land

Passive Solar & Insulation

• Highly recommended for any structure
• Building orientation: South-facing for maximum winter solar gain
• Insulation: R-30+ in ceilings, R-20+ in walls recommended
• Windows: Low-E, double-pane minimum

Cooling

• Natural ventilation sufficient for most summer days
• Evaporative coolers (swamp coolers): Effective in high desert
• Air conditioning: Generally not required at 6,400 ft elevation

Internet & Cell Coverage

Satellite Internet

• Starlink (SpaceX) — primary option for Sweetwater County. Speeds 50–200 Mbps. Service has been rapidly expanding in rural Wyoming since 2022. Equipment cost ~$600, monthly service $80–$120.
• HughesNet — geostationary satellite. Slower (25 Mbps), higher latency. Available everywhere.
• Viasat — similar to HughesNet.

Fixed Wireless

• Limited availability in rural Sweetwater County
• Providers: Local WISPs (wireless internet service providers) may serve the area
• Speed: 25–100 Mbps typical where available
• Verify: Check coverage maps with local providers

DSL

• Not available at the property
• Verizon DSL service ends at most rural areas

Cell Coverage

• Verizon: Best coverage in Sweetwater County. Intermittent 4G/5G on the property.
• AT&T: Limited coverage. Generally weak signal.
• T-Mobile: Limited coverage.
• Signal boosters: Recommended for reliable cell service. Wilson Electronics, weBoost, and SureCall make popular boosters.
• Verify: Check coverage maps at the exact property location before relying on cell service

Phone Service

• Landline: Not available
• VoIP: Works over Starlink or other internet
• Cell phone: Primary voice service for most property owners
• Satellite phone: Available as backup for emergencies (Iridium, Inmarsat)

Trash & Recycling

• Curbside pickup: Not available
• Nearest transfer station: Sweetwater County solid waste facilities
• Self-haul: Property owners typically haul trash to the transfer station
• Recycling: Limited; metal recycling available locally

Mail

• Mail delivery: Not available at the property

• PO Box: Recommended for property owners who don't live on-site full-time

Security

• Property security is the owner's responsibility
• Trail cameras: Common for monitoring wildlife and detecting trespass
• Alarm systems: Available for cabins (cell-based or satellite)
• Wildlife conflicts: Bear-resistant food storage recommended if camping

Estimated Off-Grid System Costs

A complete off-grid setup for a modest cabin (1,000 sq ft, 2 bedrooms):

• Solar + battery: $30,000–$50,000
• Well drilling: $20,000–$30,000
• Septic system: $10,000–$15,000
• Propane tank + lines: $3,000–$5,000
• Starlink installation: $1,000–$2,000
• Cell signal booster: $500–$1,500
• Total: $65,000–$105,000 (before structure cost)

This is comparable to the cost of extending grid power over 1+ miles, and provides complete energy independence.
