The Department of Water Management is beginning a project to develop a hydraulic model of the sewer collection system which drains to the South Durham Water Reclamation Facility (SDWRF). As part of the model development process, survey crews will access large-diameter sanitary sewer outfall easements in order to perform survey and assessment activities. This survey activity is expected to begin in November 2018 and last approximately five months. Crews will also install hydraulic flow meters in 26 locations throughout the sewer collection system which drains to the SDWRF. These meters will be installed from November 2018 to February 2019. Crews will return to these sites frequently to perform required maintenance and calibration activities.
