The Edgartown Wastewater Facility has been named the recipient of the New England Water Environment Association’s 2011 Energy Management Achievement Award for its efforts to reduce energy use in the treatment of wastewater.

Facilities manager Joe Alosso has utilized more than $300,000 in state and federal grants to fund cost-saving improvements at the treatment plant.

The upgrades, which include the installation of rooftop solar panels, the replacement of low-efficiency heating systems, motors and lighting fixtures, and the installation of an automatic dissolved oxygen system, should save Edgartown residents and taxpayers approximately $30,000 per year.
