Week 4 - Participation 1
GIS 4102
GIS can be used in a number of different ways. The Town of Mooresville, North Carolina utilized GIS to assist them with a stinky situation. In 2010 the town discovered they were having a problem with an increasing number of overflows and stoppages in their Sanitary Sewer System.
The Mooresville Water/Sewer Maintenance Department (WSMD) reached out to their Engineering Department for a solution to meet the requirement set by the North Carolina Department of Environment and Natural Resources. This requirement involved the cataloging of the cleaning and maintenance of all sewer lines on a regular basis to identify troubled areas. Cataloging their findings in Excel spreadsheets, the WSMD logged the cleaning data for the entire month and dates for when the sewer features were cleaned. They gave each manhole a unique identifier to associate it with a matching manhole on the GIS map.
Then utilizing Python scripting, they were able to simplify the repetition of the steps required to create the cleaning data. Python script was made available to all ArcGIS users to do analysis on the data which allowed them to determine the number of sewer mains cleaned as well as the total lengths.
The analytical data that was collected was then used to determine “hot spots” that were cleaned seven or more times in the previous year. This allowed the WSMD staff to work with other departments to isolate and monitor locations that were repeatedly cleaned. Overall the WSMD saw an increase in productivity by 26% and a decrease of stoppages in gravity main lines throughout town. This in turn, through the use of technology and teamwork, has saved the WSMD money as well as cut down on overtime.
