DEHE Division of Environmental Health & Engineering ANTHC’s Division of Environmental Health & Engineering Division of Environmental Health & Engineering Public Sanitation Health Facilities and Clinics Operations and Maintenance (O&M) and Training Alaska Rural Utility Collaborative (ARUC) Environmental Health Rural Energy Initiative DEHE, a segment of ANTHC, is composed of many different programs, including sanitation, energy, environmental health, health facilities/clinics, ARUC and operations and maintenance and training.

The Energy Intensive Arctic Sanitation System ANTHC Rural Energy Initiative The Energy Intensive Arctic Sanitation System

Understanding the Arctic Water-Energy Nexus ANTHC Rural Energy Initiative Understanding the Arctic Water-Energy Nexus Breakdown of average operating costs for a water/sewer system in rural Alaska

ANTHC Rural Energy Initiative EPA Recommended Sustainability Threshold Lower 48 Average Water and sewer bills in rural Alaska range from $80 to $250 per month, and average 3-8% of median household income; this confluence of factors is a direct threat to the sustainability of public sanitation across rural Alaska.

Our Path: A Comprehensive and Collaborative Approach ANTHC Rural Energy Initiative Our Path: A Comprehensive and Collaborative Approach Onsite Assessment Collect Data Evaluate Operating Practices Assess Facility Energy Use Develop Energy Model Identify Potential Improvements Identify Cost to Implement Develop Training Plan Purchase Materials Implement Efficiency Retrofits Provide Operator Training Construct Renewable Energy Systems Monitor Energy Usage Evaluate Retrofit Effectiveness Energy Audit Analysis Implement Recommendations Savings

Energy Efficiency Retrofits – Pilot Station, Alaska ANTHC Rural Energy Initiative Energy Efficiency Retrofits – Pilot Station, Alaska Training and small scale improvements. Saves sanitation system over 1,000 gallons of fuel oil and 25,000 kWh annually Equates to 66% reduction in Fuel and 33% drop in electricity Combined annual savings of $11,090 BEFORE: Brushing & cleaning soot from boiler AFTER: Clean flue passage 4

Power Plant Heat Recovery – Savoonga, Alaska ANTHC Rural Energy Initiative Power Plant Heat Recovery – Savoonga, Alaska Utilize excess heat from diesel power plant to heat the community sanitation system. Reduces water plant heating fuel usage by 90% (8,800 gallons) annually Annual savings of almost $40,000 per year 4

Biomass Heating – Kobuk, Alaska ANTHC Rural Energy Initiative Biomass Heating – Kobuk, Alaska Replace diesel with locally harvested cord wood to heat community water system. Reduces heating fuel usage by 3,000 gallons annually Annual savings of almost $24,000 per year Creates local jobs for woodcutters and operators 4

Excess Wind-to-Heat – Mekoryuk, Alaska ANTHC Rural Energy Initiative Excess Wind-to-Heat – Mekoryuk, Alaska Utilize dispatchable wind electricity to provide heat to the sanitation system. Cost of $0.05 per kWh equivalent to fuel oil at $1.46 per gallon Projected annual savings of almost $40,000 4

Geothermal Ground Source Heat Pump – Metlakatla, Alaska ANTHC Rural Energy Initiative Geothermal Ground Source Heat Pump – Metlakatla, Alaska Vertical Well GSHP system will replace oil fired heating at the Lepquinum Pool & Wellness Center Heat Pump will cover 94% of yearly heating load Building heating system upgrades required 2 existing oil-fired boilers will remain as backup and for peak heating Energy Savings = $202,000 per year

ANTHC Rural Energy Initiative Current and Identified Projects Through 2018 We believe basic sanitation should be efficient, sustainable and affordable
