The City of Morristown, in accordance with a Tennessee Department of Environment and Conservation Order embarked on a major field investigation effort. The purpose of the field investigation was to develop an accurate condition assessment, location, and rehabilitation recommendations for over 250 miles of infrastructure. The City had an existing Geographic Information System (GIS), but there were few attributes and conditions associated with the system. LDA partnered with City staff forming 4 field crews to investigate the data. A new unique naming convention was developed, and then the system was broken down into individual basins. The known “problem” areas were investigated and characterized first, allowing for rehabilitation efforts to run concurrently with field operations.
LDA investigated infrastructure noting construction, condition, and location within the field databases. These databases automated a “scoring system” which could be used for determining basin characterizations. Field crews also collected pictures, videos, and “on the ground” measurements which were added to the field sketches. Also, LDA coordinated with several outside contractors to gain additional field information including CCTV.
All field investigative information was compiled to a geodetabase and entered into the GIS system. LDA used this information, as well as current flow data to develop a hydraulic model of the entire system. The GIS system was separated into basins and map books initially, which allowed for immediate generation of rehabilitation plans. In addition, LDA was responsible for creating a SORP, comprehensive Management, Operations, and Maintenance Program, and Phase I&II collection system CAP/ER. LDA then assisted the City in forming a GIS co-op to share data with multiple entities within the County.Back to Projects
