HomeMy WebLinkAboutGM Update Report-September 2026 September 16, 2026 TO: Chair and Members of the Board of Directors FROM: Robert C. Thompson General Manager SUBJECT: September Status Report The following report provides an update on key organizational accomplishments and activities. 1. Public and Environmental Health Winter Weather/Wet Season Preparation OC San is preparing for the 2026–2027 wet weather season to ensure continued treatment reliability during periods of elevated flows or other abnormal conditions. The Operations and Maintenance Department is focused on maintaining the readiness of major equipment, ensuring adequate chemical inventories, and confirming the availability of portable response equipment. Weather forecasts and plant conditions are closely monitored throughout the season, allowing staff to take timely actions to maintain reliable operations and protect public health and the environment. 2. Sound Finances and Increasing Efficiency Annual Report: Connection - People, Projects, and Purpose The Fiscal Year 2025-26 Annual Report, which focuses on the year’s accomplishments highlighting the connection between people, projects, and purpose, will be showcased at the State of OC San. The report will be available on OCSan.gov following the event. 3. Recovering Valuable Resources Resource Recovery Helps Power OC San OC San maximizes resource recovery by using biogas generated through the wastewater treatment process as a renewable fuel for Central Generation (Cen Gen). In Fiscal Year 2025-26, Cen Gen produced approximately 86,492 megawatt-hours of electricity, supplying roughly two-thirds of OC San’s electrical power needs for Reclamation Plant Nos. 1 and 2. In addition to electricity generation, recovered heat from Cen Gen supports digester operations necessary for permit compliance and Chair and Members of the Board of Directors September 16, 2026 Page 2 of 3 provides hot water for select facilities, further improving OC San’s efficiency and beneficial use of renewable resources. 4. Community Outreach and Transparency Engaging with our Public OC San hosted facility tours for Cypress High School, Whittier Christian High School, new OC San employees, and members of the public. Additionally, I provided a tour for the Orange County Grand Jury. OC San is also participating in two community events: the Cypress Community Festival and Coastal Cleanup Day. Staff will also be attending and hosting a booth at the OC Water Summit, participating in the Healthy Living Expo in Irvine, joining the OC Water Association-Women in Water Panel, and organized a Careers in Wastewater Day at the City of Orange library. Community Connection Newsletter OC San will release the fall issue of the community newsletter at the end of September. This issue will highlight important seasonal topics, including fats, oils, grease and What2Flush, with helpful reminders as we head into the holiday season. It will also feature updates on major construction projects, including the progress on the Santa Ana Sewer Rehabilitation Project and an update on the Huntington Beach Wall Project. The newsletter will be shared with the community through the OC San website, social media, and email. Previous issues can be found at www.ocsan.gov/newsletter. 5. Legislative and Industry Affairs Legislative Update • Federal Congress returned to session on September 14 for approximately ten legislative days before recessing again ahead of the midterm elections. This schedule means that the majority of outstanding legislative business will happen during the post-election Lame Duck session. • State California’s 2026 legislative session concluded on September 1, with lawmakers working through a highly compressed final stretch to address more than 1,200 active measures, including fiscal committee hearings, floor votes, concurrence decisions, and late-stage negotiations. As of September 8, approximately 900 bills remain on the Governor’s desk, with Governor Newsom having until September 30 to sign or veto the remaining legislation. Chair and Members of the Board of Directors September 16, 2026 Page 3 of 3 6. Workforce and Administration Employee Development Week OC San is launching its inaugural Employee Development Week, “Fuel Your Future,” the week of September 28 reinforcing the agency’s commitment to developing internal talent and preparing for future workforce needs. The week will feature employee career perspectives, development planning resources, professional headshots, and information on OC San’s tuition and certification reimbursement and development pay programs. This initiative builds on OC San’s year-round workforce development efforts by increasing awareness of available resources, encouraging professional growth, and supporting a skilled and prepared workforce.
