Riviera Utilities experienced a Sanitary Sewer Overflow (SSO) on October 14 at the Wolf Creek WWTP. The clarifier experienced a hydraulic overload during a rain event. Partially treated sanitary sewer flowed through the UV disinfection system and reached Wolf Creek. Once the overflow was discovered, flows were diverted to the lagoon to temporarily reduce the flows to the WWTP. The secondary UV system was activated in order to aide with disinfection.
