Case Study: L.A. County Finds Reliable Pump Monitoring with

Posted on Fri, May 20, 2011 @ 12:03 PM

On July 15, 2006, a power outage at a Manhattan Beach, Calif., pump station resulted in the largest wastewater spill in a decade. Although the facility had a SCADA system in place, a combination of equipment and communication failures occurred, causing extreme flooding. Sanitation Districts of Los Angeles County officials knew that such an event could never occur again, so they turned to RACO for a solution.

Many cities and unincorporated areas in Los Angeles County are separated from the main metropolitan area by mountains, so communications options are limited. The current SCADA system used landlines, so a backup system would need to use either radio or wireless technology. RACO personnel visited the system’s most important pump stations and determined that the web-based would be best.

To get the Sanitation Districts of Los Angeles county started with the system, RACO personnel visited their offices to educate personnel on using the website. They also visited all of the pump stations to ensure each had the necessary signal strength and sent out test units for Sanitations Districts employees to try.

Today, all 53 pump stations in Los Angeles County use for alarm notification backup. An operations team runs a field office to monitor the system for the entire county, monitoring the pump stations and coordinating response teams any time an alarm occurs.

The system has proved its worth on many occasions, including an incident that occurred just hours after it was installed. A pump station on Pacific Highway #1 lost power, cutting out the SCADA system. was able to notify personnel, who were able to monitor the situation until power was restored.

The Sanitations Districts have been so pleased with the system for their wastewater management operations that they decided to implement it for their solid waste operations, too. An system recently was installed in an L.A. County landfill, one of the largest in the country.
