Abstract:

Water and wastewater treatment facilities typically represent one of the primary consumers of energy in a community. A progressive wastewater utility, the North Conway Water Precinct, reduced its energy costs in an environmentally responsible way by improving the energy efficiency of existing systems and incorporating new alternative energy technologies into its power supply portfolio. The precinct's Alternative Energy Systems project included the installation of 744 solar panels; 16 geothermal wells; heat pumps; and heating, ventilation and air conditioning (HVAC) improvements to reduce reliance on carbon-based energy sources and associated greenhouse gas emissions. This project serves as a model for wastewater facilities seeking to improve the sustainability of plant operations and reduce facility energy costs through the application of green technologies.
