Sanitary Sewer Basin Analysis + Interceptor

McAdams evaluated the build-out scenario of the sewer basin and presented the results to the Town of Knightdale. Based on the results of the analysis, McAdams designed 12,414 linear feet of 8-18-inch sanitary sewer that discharges to an existing interceptor downstream. One particular design challenge that McAdams successfully addressed was that this interceptor would pass under the future I-540 Northern Wake Expressway, and therefore, careful coordination with North Carolina Department of Transportation (NCDOT) was required so that the depth and alignment of the interceptor would coincide with the future I-540 design. Upon completion of the design efforts, McAdams staff obtained the necessary construction document approvals and permits from North Carolina Department of Environment and Natural Resources (NCDENR) and encroachment agreements from NCDOT. McAdams also prepared the easement plats for the interceptor easement. In addition, the McAdams design team conducted regular inspections of construction while providing guidance to the Town and contractor for successful completion of the project.
