City Of Concord: Concord Receives ARPA Grant

Press release from the City of Concord:

The City of Concord has been awarded $760,000 by the State of New Hampshire’s Department of Environmental Services for upgrades to the secondary clarifiers at the Hall Street Wastewater Treatment Facility. These grant funds are being provided through the American Rescue Plan Act of 2021 (ARPA) as a necessary investment in wastewater system improvements.

Work is anticipated to begin in the spring of 2023 to upgrade components to the three secondary clarifiers at the facility. Improvements will include new secondary clarifier suction pipe mechanisms with fabricated steel drives, a new bridge walkway for each clarifier, new weirs and scum baffles, new scum trough for each clarifier, new perimeter density current prevention baffles, new launder covers, and new scum hatches. These components are original parts from when the facility was built in 1979 and are due for replacement.

Total project costs are anticipated around $3,800,000. The ARPA grant will assist with these costs, while the cost difference will be sourced from local funding.

Secondary clarification is an important step in the wastewater treatment process as it provides necessary time for bacteria material to settle to the bottom of the tank and become separated from wastewater. These upgrades will improve system reliability and operations in maintaining sustainable resource recovery for public health and safety, with a safe return to our environment and protection of the water quality of the Merrimack River.
