The devastating water incident in Flint Michigan, the California water crisis, and unforeseen events like hurricanes Sandy and Matthew increasing the wastewater/sewage population in NJ and NC, highlight key issues within the water and wastewater industry. Though these complications lay in the lack of Renewal & Replacement (R&R) of aging water and wastewater infrastructure and the poor financing for capital improvements, it is unplanned downtime that remains a significant issue within the water industry. The failure of SCADA control causes multiple issues, such as:
- An inability to control remote locations
- Loss in integration with reliability systems
- Loss of data/report generation
- “Blindness” from the plant level to the entire district
However, Updating Aging Water/Wastewater Control Systems Can Yield Quick Returns and Prepares for Future Applications
The challenges with traditional water/wastewater supervisory and control systems lay in hardware, antiquated/outdated operating systems & software, and personnel. The traditional hardware typically has multiple single points of failure, with the failure rate and supporting costs increasing exponentially after five to seven years. Antiquated/outdated operating systems & software usually contain cyber-security vulnerabilities, are subject to extended downtime and are difficult and expensive to upgrade. Personnel challenges include institutional knowledge held by an aging infrastructure.
The solution to these challenges lies in virtualization – which is a key component for L2/L3 modernization. Implementing virtualization technology to run on SCADA systems reduces the number of hardware platforms holding multiple applications. In addition, it provides cost-saving benefits, operational improvements, and increased productivity.
However, though virtualization is widely accepted in the IT world, OT personnel within the automation space are not as quick to adopt. This is because, with a traditional architecture, hardware failure in virtualized systems is catastrophic.
So how can this be prevented? There are many services that protect virtualized systems, however, Stratus provides solutions that are continuously available, operationally simple, and cost-effective. Stratus’ ftServer offers an automated uptime layer and fault detection isolation. Both layers of the platform run in absolute lockstep – still working seamlessly if one layer were to fail – with no data loss. Stratus also offers 24/7 service support which includes in-depth system health monitoring, dedicated availability experts, and system monitoring and diagnostics and more.
