Developing a Proactive City-Wide Stormwater CCTV Master Plan and Condition Assessment Program San Antonio, TX

Aging stormwater infrastructure is one of the biggest challenges facing communities today. With portions of the City of San Antonio’s (City’s) stormwater collection system approaching 100 years old, a comprehensive understanding of the condition and location of the existing system was needed. This paper will provide an overview of the multi-year Stormwater System Televising, Mapping, and Condition Assessment project initiated by the City in 2015; the Stormwater CCTV Master Plan development; and information about technologies used to complete the project, including: (1) mobile LiDAR for above ground survey; and (2) InfoMaster Sewer to transform the asset condition data and defect codes into GIS, conduct the system defect analysis, and develop a City-wide CCTV Master Plan for San Antonio This 6-year project provided a procedure to accurately inventory the system and understand the condition of the assets. The use of these advanced data collection and analysis technologies made it possible to complete the project according to the accelerated timeline and provided the City with detailed and useful data deliverables.
