The City of Corpus Christi agreed to participate in the TCEQ Sanitary Sewer Overflow Initiative (SSOI) outreach program, which required the development and calibration of an all-pipes wastewater system hydraulic model for the entire collection system. The City acquired the services of LNV to develop and prepare a hydraulic model for three of the city’s six treatment plant service areas (Oso, Laguna Madre, and Whitecap). These three basins included approximately 54 lift stations, 10,700 manholes and 3.3 million feet of pipe.
