On March 17, 2023, a pipe conveying sand filter backwash wastewater burst releasing about 500 gallons for about 30 minutes. The volume released to the storm drains is unknown. The discharger determined that a water hammer effect within the pipe caused it to break. It replaced the damaged pipe with a high-pressure flexible hose. On the same day, the discharger collected upstream and downstream receiving water samples within an hour of low tide. No oil sheen, fish kill, water discoloration, foam, or other indicators of contamination were observed at the outfall. |
As a corrective action, the Discharger will keep the high-pressure flexible hose section to dampen potential hammer shocks. It will establish a bi-weekly inspection schedule on plumbing components to ensure future spills are avoided. Additionally, it will remotely monitor the treatment system every 2 hours for signs of plumbing failure and perform weekly inspections on elbow joints and other weak points withing the system. |
