The purpose of this project was to increase the capacity of the existing 42-inch effluent pipeline from 20 MGD to 40 MGD while also restoring its structural stability and maintaining the same outfall location as currently identified in the city’s discharge permit. This project included design, bid and construction phase services for the rehabilitation of approximately 1,300 linear feet of existing 42-inch concrete flex-joint effluent line and the installation of approximately 2,600 linear feet of new 42-inch line parallel to the Salt Flats Drainage Ditch from the New Broadway Wastewater Treatment Plant (NBWWTP) to the Port of Corpus Christi ship channel. The rehabilitation involved slip lining a 36-inch line (HDPE or Fusible PVC) through the existing 42-inch line and grout filling the annular space.
