Central St. Water and Sewer Rehabilitation/Replace
The sewer pipe on Central St. is a clay pipe installed in 1938. The water pipe is cast iron pipe installed in 1906. The sewer pipe is mostly located in the street but crosses through two off-road areas which make access for maintenance difficult. Both pipes, due to age and material, present a significant risk for failure. The sewer pipe between Highgate Rd. and Purchase St. will be evaluated, while the water pipe between Edgell Rd. and Purchase St. will be evaluated.
Design efforts will begin with CCTV evaluation of the condition of the existing sewer and drainage pipes to determine if trenchless CIPP lining is an appropriate approach. CIPP lining would reduce the extent of excavation and disturbance to the street and would be a less expensive option for the repair of the sewer pipe. Other initial design efforts will include survey, geotechnical testing, and evaluation of relocating the pipes in the off-road areas back into the street. This work began in the Spring of 2019. Funding is now approved for the design of water and sewer rehabilitation.
The project includes the replacement or rehabilitation of approximately 2.5 miles of water main and 2 miles of sewer main on Central Street. Also, the replacement of water main on Kellogg St. The goal of the project is to improve service conditions (e.g., fire flows) and reduce maintenance issues due to old infrastructure.
Initial design efforts included a condition assessment of sewer and drainage pipes, survey, geotechnical evaluation, and research of historical data. This work began in the Spring of 2019. Funding is available for the design of water and sewer rehabilitation, and design work will continue through 2020.
Preliminary design work is complete and included soil and pavement borings, geotechnical evaluations, wetland delineation, CCTV of sewer and drainage pipes, and survey of the entire corridor. The design of water and sewer rehabilitation or replacement has progressed to 30%.
Currently, there is no funding for drainage, sidewalk, or roadway improvements. However, future improvements to the drainage will be factored into the sewer and water design to avoid utility conflicts. Construction is contingent upon funding and will be completed in phases due to the scale of the project and to mitigate impacts to residents.
