Wastewater Interceptors and Trunk Line
Harker Heights, Texas

TCE’s contract with Harker Heights consisted of constructing three major wastewater gravity sewers totaling 9,000 L.F. Line size diameters ranged from 10 inches to 27 inches. Various pipe materials were used including PVC SDR 35 and large diameter PVC of PS 46 rating meeting ASTM F-794 requirements. The new larger diameter sewer lines replaced existing sewer lines and were designed and constructed to keep sewer collection facilities in service during construction. One new interceptor line was designed to relieve an existing lift station.
