Document Description
The Proposed Project would consist of the replacement of approximately 5,500 linear feet of existing 20- to 24-inch diameter sewer trunk main with new 27- to 36-inch diameter pipelines. The purpose of the Proposed Project is to replace or rehabilitate the trunk sewer while meeting capacity requirements and allowing for future maintenance. In general, due to physical constraints such as property ownership, wetland locations, deep pipe and adjacent trees and retaining walls, the trunk sewer will be replaced in the existing horizontal alignment except where this is not feasible or practical.
