YARMOUTH — The town has received a $55,344 grant to upgrade the wastewater treatment plant.

The grant was awarded by Efficiency Maine through federal energy funding. The money will be used to make the electric aerator motors at the plant more energy efficient. The Yarmouth Energy Savers Committee and town officials applied for the grant in November. The project will also receive $5,600 from the town and a $500 in-kind donation.

The plant accounts for 40 percent of municipal energy used in Yarmouth. In a news release, town engineer Dan Jellis said the project has the potential to reduce the motor’s energy use by 15 percent and save Yarmouth $8,284 each year.
