One System, One Plan, One Happy Town
The Belleville Conservancy District, located in southern Hendricks County, was formed in the mid-1980's to provide sanitary
sewer service to the small community of Belleville and the surrounding area. In 2006, a number of these facilities were
beginning to show their age and the flows into the wastewater treatment plant greatly exceeded its capacity. The nearby
Town of Plainfield offered to take over and incorporate it into the Town's existing wastewater system.
After making a number of immediate improvements, the Town began developing a long-range plan for upgrades and enhancements to
the Belleville system. GPS points were collected - including elevations - for major structures in the collection system. The
Town was then able to identify sewers that had too much or too little slope.
The Town also used SewerCam to collect video of the system. These images and videos were hyperlinked to corresponding
features in the Geographic Information System (GIS), and combined with existing surveyed information. With a wealth of
accurate information at their fingertips, the Town was able to effectively analyze and prioritize sewer defects based on
location, type, and urgency.
Results
By using GIS to tie the other disciplines together, the Town was able to:
- Generate a a precise and accurate inventory of the entire wastewater treatment system
- Gain extensive access to their inventory, including point-and-click access to the sewer videos
- Develop a logical, empirical method of prioritizing repairs and upgrades
- Perform computer modeling to develop an informed maintenance plan
