Utilities & Off-Grid

Power, water, sewer, internet, and connectivity for the Wyoming parcel.

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, typical costs, and 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 is typical for a modest cabin or home.
• **Annual production:** Roughly 7,500–15,000 kWh — Sweetwater County sees abundant sunshine.
• **Battery storage:** 20–40 kWh lithium-ion (Tesla Powerwall, Enphase, or similar).
• **Generator backup:** A propane or diesel generator is recommended for winter and cloudy periods.
• **Estimated system cost:** $25,000–$50,000 for a complete turnkey installation.
• **Incentives:** Federal tax credits for residential solar may be available; check current law at the time of installation.

Wind Power

• **Small wind turbines:** Viable in Sweetwater County's persistent winds.
• **Cost:** Roughly $5,000–$20,000 for a residential-scale turbine.
• A combined solar-plus-wind configuration is common 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 permits rainwater harvesting for non-stock use (verify current law).

Water Hauling

• **Cost:** Roughly $0.10–$0.20 per gallon delivered in the area.
• **Tank size:** 1,000–3,000 gallon tanks are 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. The nearest surface water is the Green River, approximately 15 miles south.

Sewer

Septic System

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

Composting Toilet

A viable alternative for cabins used part-time. No permits are required in most cases (verify with the county). Installed cost is typically $1,000–$3,000, with periodic emptying of compost.

Greywater

Greywater may be used for subsurface irrigation of landscaping, subject to Sweetwater County greywater disposal regulations.

Heating & Cooling

Propane

• **Source:** Local propane companies in Rock Springs.
• **Delivery:** Scheduled bulk delivery to an on-site tank (typically 500–1,000 gallons).
• **Cost:** Roughly $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, clothes drying, generator backup.

Wood Heat

Viable in Sweetwater County — juniper and pine are available on and near the property (with proper permits). Cost is mainly labor for cutting and splitting. Permits may be required for cutting on BLM land.

Passive Solar & Insulation

Highly recommended for any structure: south-facing orientation for maximum winter solar gain, R-30+ insulation in ceilings, R-20+ in walls, and low-E double-pane windows at a minimum.

Cooling

Natural ventilation is sufficient for most summer days. Evaporative coolers (swamp coolers) are effective in the high desert. Air conditioning is generally not required at 6,400 feet elevation.
