Both SJWD and SCDHEC receive monthly updates which accurately flag any potential issues that may arise. For the regulator, this means enhanced data between inspections that enable correct dam classifications and safer dam infrastructure. South Carolina DHEC is provided with a greater level of confidence in the efforts taken to monitor assets that could have large potential impacts if not properly managed and maintained.
While for owner SJWD, public safety and efficiency can be drastically improved. Data on ground motion and seepage, as well as new housing developments, ensures engineer resources are directed to the right place at the right time. This not only saves on costs but helps to reduce the risk of dam failure.
Starting the monitoring program in December 2020, early results show the technology is helping SJWD to identify anomalies that would otherwise go unnoticed. For example, in one dam in particular, the technology identified an area that had stayed wet, typically suggestive of seepage. Another dam being monitored experienced a partial failure of the emergency spillway due to flooding in early February last year. Despite being a construction site during the early parts of the program, the Rezatec solution picked up these changes.
