Richmond’s NW 13th Street Interceptor Replacement Project
The NW 13th St. Interceptor Replacement Project was recently completed and involved upsizing 3.5 miles of aged gravity sanitary interceptor with new 24–36-inch diameter pipe using a combination of open-cut and trenchless construction. The project is an important component of the City’s goal to reduce overflows on the west side of Richmond and to comply with the City’s Long Term Control Plan.
This unique project involved many challenges such as (a) installing a 36-inch diameter siphon under the Whitewater River using horizontal directional drilling, (b) replacing two existing aerial sewer crossings across wooded ravines, (c) constructing sewers in Earlham Cemetery and Earlham College, (d) monitoring a railroad bridge for settlement, and (e) ensuring that future sewer improvement phases will be successful.
