Abstract

Migrating storm and sanitary sewer infrastructure into GIS
Track: Water, Wastewater, and Storm Water
Authors: Brian Waldron, Aaron Robinson, Ryan Csontos

A GIS solution was developed to digitize the storm water and sanitary sewer infrastructure within the City of Memphis. The two efforts utilize a versioned geodatabase architecture that takes advantage of geodatabase topology and subtype/domain functionality. These functions help provide a real-time QA/QC. Undergraduate and graduate students at the University of Memphis interpret data such as geo-rectified and geo-located engineering drawings depicting complex engineering infrastructure, utilizing aerials, Pictometry, digital elevation models, and other relevant data. The approximate 50,000 engineering drawings were geo-rectified or geo-located prior to digitizing the infrastructure. Project progress is illustrated using ArcGIS Server web services. Migrating this 100 year-old paper dataset into GIS will improve workflow efficiencies, provide greater sharing of information across city divisions, and reduce line breakage on construction sites. At present 10-20% of the City of Memphis' sanitary and storm water infrastructure is completed, with plans to complete the project within 5 years.
