The Districts are responsible for maintaining an interior drainage system of sloughs and ditches to remove stormwater. In order to do this, the Districts maintain and operate 10 pump stations via one centralized Supervisory Control and Data Acquisition (SCADA) system.

The current SCADA system was installed between 2001 and 2002 and needs upgrades due to frequent system crashes, false alarms, low speed connection, and inaccurate data. The purpose of this project is to upgrade the current system to provide more functionality, reliability, and performance for MCDD staff to manage its stormwater conveyance system.
