GNHWPCA Large Diameter Pipe Cleaning Program

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.Work crews clean the pipe using high pressure water hoses, cleaning heads and vacuums to extract the debris. Video cameras are also used to inspect the pipe prior to and post cleaning of the sewer pipes. As such, residents may see activities related to the large diameter pipe inspections for several weeks leading up to the actual cleaning of the pipes.

Notices will be provided to residences and establishments in advance of any large diameter sewer cleaning work on their street.

GNHWPCA Pipe Lining Program

GNHWPCA Pipe Lining Program

Pipe lining is a trenchless rehabilitation process used to repair existing pipelines. Benefits include:

  • pipes can be rehabilitated without disturbing the surrounding neighborhoods and businesses,
  • lining is less expensive than replacing the pipe,
  • it allows for increased sewer flow capacity.
  • the process can be completed in one to three days.

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.

Notices will be provided to residences and establishments in advance of any sewer lining work on their street. Notices will be provided by the GNHWPCA’s contractor both 10 days prior to and 24 hours prior to the conduct of the expected work.
