Installation of Catch Basin on Prospect Street

GNHWPCA Large Diameter Pipe Cleaning Program :
GNHWPCA’s large diameter sewer pipes range from 30 inches in diameter to 84 inches in diameter. Most of these large diameter sewer pipes are main interceptor sewers located in the City of New Haven that transport combined flow to the ESWPAF for treatment. Periodic cleaning of these interceptor sewers is required to remove sand, grit, rocks, and other heavy debris that can accumulate in the pipe over time


GNHWPCA Pipe Lining Program :
Pipe lining is a trenchless rehabilitation process used to repair existing pipelines.
Prior to lining the existing sewer, crews clean the pipe using high pressure water hoses and video cameras to inspect the pipe condition. They may also conduct dye testing to confirm connections between buildings and sewers. As such, residents may see activities related to the sewer relining for several weeks leading up to the actual lining. 


Is Green Infrastructure Coming to Your Neighborhood? : 
As part of the implementation of the City of New Haven's Long Term Control Plan, many green infrastucture (GI) projects are being constructed in rights-of-way on City streets, sidewalks, and on other municipal properties.  GI uses vegetation, soils, and other elements and practices to restore some of the natural processes required to manage water and create healthier urban environments.


East Haven Pump Station Resiliency Implementation : 
The GNHWPCA applied for and received funding from the Federal Emergency Management Agency (FEMA) Hazard Mitigation Grant Program (HMGP) to implement resiliency improvements at four coastal pump stations located in East Haven, CT.  The intent of the East Haven Pump Station Resiliency Implementation Project is to implement resiliency improvements at GNHWPCA's Cosey Beach, Minor Road, Meadow Street, and Farview Road Pump Stations to reduce/eliminate the long-term risk of flood damage to these pump stations.
