Concord General Services Department – Concord, NH

Concord General Services – Wastewater and Public Properties

The Concord General Services Department operates a critical facility at 125 Hall Street, primarily housing the Wastewater Treatment Division and the Public Properties Division. While the department’s administrative headquarters is located on North State Street, this Hall Street location serves as the operational hub for maintaining the city’s essential sanitation infrastructure and municipal buildings. The facility plays a vital role in protecting public health and the environment by managing the collection and treatment of wastewater from Concord and portions of neighboring communities like Bow and Boscawen. It is also the base of operations for the teams responsible for the upkeep, repair, and maintenance of all city-owned facilities, ensuring they remain safe and functional for public use.

Wastewater Treatment Operations

The Hall Street Wastewater Treatment Facility is the city’s primary plant for processing sewage and wastewater. It utilizes advanced treatment processes to remove contaminants before discharging treated water back into the Merrimack River, strictly adhering to state and federal environmental regulations. The division manages a vast network of sanitary sewer lines and pump stations throughout the city. Staff at this location oversee the 24/7 operation of the plant, monitor water quality, and handle the processing of biosolids. This facility also accepts specific types of waste, such as septage from local haulers, playing a key region-wide role in waste management.

Public Properties Maintenance

Sharing this location is the Public Properties Division, which is tasked with the comprehensive maintenance of Concord’s public infrastructure. This includes the City Hall, libraries, fire stations, police headquarters, and community centers. The skilled tradespeople based here—including electricians, plumbers, and carpenters—respond to work orders and perform preventative maintenance to preserve the city’s physical assets. They are also responsible for the maintenance of the Douglas N. Everett Arena and other recreational facilities. During winter months, crews from this location assist with snow removal efforts around public buildings, ensuring safe access for residents and employees.
