Upgrading aging infrastructure without breaking the bank
Like many municipalities, the Town of Clarkstown was starting to face a number of challenges due to aging infrastructure: sewer overflows due to failing equipment and a lack of emergency power generation; stormwater inflow from surface runoff; and groundwater infiltration through cracked pipes and leaking joints.
With financial assistance from the Rockland County Sewer District, the Town of Clarkstown established a capital improvements program to replace outdated technology and bring the Town’s pump stations into compliance with the most current Ten States Standards.
Reducing stormwater inflow and infiltration in gravity sewers reduces the demand on pump stations and receiving sewage treatment facilities. H2M is currently upgrading nine of Clarkstown’s sanitary sewage pump stations to include new pumps and controls, valves, and force main piping to connect to existing force mains. We are utilizing precast structures such as wet wells, valve vaults, and control buildings to minimize on-site construction, and we’ve selected architectural finishes, fences, and landscaping to incorporate the pump stations into the local residential neighborhoods.
Emergency standby generators will be supplied to all nine pump stations to ensure that equipment will continue to operate in the event of a power outage.
