Sanitary sewer construction with polypropylene pipe

Five months from start to finish: The interceptor project replaced 24- and 30-inch vitrified clay pipelines with 5,600 feet of 60-inch polypropylene pipe. Buried 8 to 22 feet down, the pipe — Advanced Drainage Systems' SaniTite HP — has maintained shape regardless of depth. Photos: Advanced Drainage Systems

Instead of precast concrete, ADS used the 60-inch pipe to fabricate manholes with H-20 load rating and fill heights. Once in place, each was encapsulated in concrete with a field-placed steel reinforcing cage.

About 200 feet of pipe in diameters ranging from 24 to 48 inches was used for laterals that were connected to the main trunk using Inserta Tee and fabricated fittings.
