The District's collection system is the network of underground pipes, manholes and pumping stations used to collect wastewater from businesses and residences. Once the wastewater has entered the collection system, this network transports it to either CTRWD's Michigan Road Wastewater Treatment Plant or to the City of Carmel Wastewater Treatment Plant near 96th Street and Hazel Dell Parkway where CTRWD owns reserved capacity.
The system has been under almost continuous expansion since the District was formed, primarily due to the explosive real estate market demand over the last decade for residential and commercial development in the southern part of Hamilton County.
The network is monitored through a SCADA (telemetry) system and allows remote access for monitoring and controlling system functions at lift stations and the District's treatment plant. The infrastructure is maintained with the help of an asset & work management software program provided by CarteGraph.

This video clip is an example of infiltration into a manhole in Austin Oaks. The sewer is flowing to the left, but you can see and hear the ground water shooting in from the left connection boot around the pipe. This manhole was repaired by using epoxy to plug the hole.
