Order Conditions |
During the reporting period, the South County Regional Wastewater Authority experienced a violation of the
recycled water total coliform effluent limitation at Monitoring Location EFF-003 (Discharge Point 003).
Specifically, the 7-day median total coliform concentration exceeded the permit limit of 2.2 MPN/100 mL, with
a measured value of 4.1 MPN/100 mL during the monitoring period of May 12, 2026 through May 18, 2026. |
The cause of the exceedance was determined to be fouling within the UV disinfection channels, which reduced
disinfection performance. Corrective actions included cleaning the UV channels and increasing inspection and
maintenance frequency of the UV system. |

On August 5, 2025 at 11:53am our UV system had a flow exceedance. This lasted for 30 seconds. The UV system is rated for 4.5MGD and we saw a peak flow of 5.8MGD |
Operations staff responded immediately to
the alarm and verified that the flow returned to normal within seconds.
The incident was logged and reviewed internally.
Preventive Actions Implemented
Staff have adjusted the effluent valve control logic to limit the speed of valve opening rates.
A procedural update has been issued requiring manual verification of valve positions before bringing filters online.
Additional training has been provided to operations staff on surge mitigation during filter transitions.
