Supervisory Control and Data Acquisition

(SCADA) Project

 

The Supervisory Control and Data Acquisition (SCADA) project consists of replacing a land-line based alarm monitoring system with a wireless radio-based system. The project includes both a water and wastewater segment. This is a Priority 1 Capital Improvement Project that will resolve an urgent health/safety need in the CCSD's infrastructure. Cost projections for the combined water and wastewater segments are $417,000. The project is estimated for completion will depend upon financial capabilities of CCSD.

 

Water Segment

The water portion of the SCADA project will be applied to critial infrastructure components within the water distribution system including wells, remote pumping stations, emergency power generators and storage tanks. The use of land lines for remote monitoring and alarms has proven to be unreliable due to most of the lines running overhead and being subject to failure during storms and fire events. Such failures can come at the most critical times, which would be particularly true during a major fire. Past failures of the land lines have also resulted in tanks overflowing or not fill properly.

 

The new radio-based system will improve overall system reliability while also reducing monthly land-line lease expenses. The system will provide better control of the distribution system operations, while also serving to protect the existing water infrastructure.

 

Wasterwater Segment

The wastewater portion of the SCADA project will be applied to a backbone system that will link the main wastewater treatment plant equipment and processes. The remaining project work will link remote lift stations to the Wastewater Tretment Plant operations center.

 

Failures of the land lines during storm events may lead to sewer overflows if operators are not notified of lift station malfunctions or related equipment failures. The new radio-based system will improve overall system reliability while also reducing monthly land-line lease expenses. The system will provide better control of the Wastewater Teatment Plant processes and remote sanitary collection lift stations.
