Piedmont Sewer Repair Project Update: July 8, 2016

Piedmont Sewer Repair Project Update: July 8, 2016

Environmental Services continues construction on the Piedmont Sewer Repair Project. The project is repairing or replacing almost 11,000 feet (over 2 miles) of public sewer pipes in your neighborhood that are on average 90 years old and deteriorating due to age. The work also includes repairing or adding over 2,000 feet of service laterals that connect houses and businesses from the curb to the public sewer in the street. This project will help protect the public and the environment by reducing the possibility of costly breaks, leaks, blockages and sewage releases to homes, businesses and streets.


Cured in place pipe lining (CIPP) is scheduled to continue next week.

  • Crews are repairing main line public sewer pipe in several locations using the CIPP construction method.  Go to to view a map. Go to to view photos and learn more about cured in place pipe lining.
  • After all mainline CIPP repairs are complete, residents should expect a period of inactivity while quality control inspections are performed. Once it’s determined that the repairs meet city standards, crews will return to repair public sewer lateral pipes that connect homes and businesses to the mainline.


Preparation for pipe bursting on N Haight Avenue between Morgan and Bryant streets has been rescheduled for the week of July 18.



Construction hours are from 7:00 a.m. to 6:00 p.m. Monday through Friday. Below is the estimated construction schedule for the next two weeks.
