Project Overview

Environmental Services is nearing completion on the Humboldt neighborhood, the work includes repairing over 17,000 feet of public sewer pipes, that are on average 90 years old and deteriorating due to age. This work will include repairing or adding service laterals that connect houses and businesses from the curb to the public sewer in the street/alley. Taking these actions now will help protect the public and our environment by reducing the possibility of costly breaks, leaks, blockages, and sewage releases to homes, businesses, and streets.


Major sewer construction and street restoration as part of the Humboldt Sewer Repair Project are complete.

  • Remaining work  includes completing miscellaneous outstanding items such as spot paving, additional manhole repairs, moving materials and equipment from the area, and cleaning. 
  • Completion of outstanding items may extend into June. 


The map indicates locations where work will occur, and the construction method that will be employed. You can learn more about construction methods HERE.
