Descriptiontext

Oro Loma Sanitary District is a California special district (a form of local government entity organized under the California Health and Safety Code) that provides wastewater collection and treatment, solid waste collection, and recycling services to approximately 45,000 residents and businesses across San Lorenzo, Ashland, Cherryland, Fairview, and portions of San Leandro, Hayward, and Castro Valley in Alameda County. The district operates a wastewater treatment plant in the 5–20 MGD Medium Plant category, recognized by the California Water Environment Association as "Plant of the Year" for compliance and treatment innovation, and runs supporting infrastructure including lift stations, CCTV sewer inspection systems, and sewer cleaning operations. It also delivers nature-based infrastructure through the Horizontal Levee Project, household hazardous waste programs, public tours, and a Wastewater Surveillance Program; the district does not provide drinking water.

The district's revenue is generated entirely through recurring utility-style service charges and fees. It bills residential and commercial customers monthly for wastewater sewer service charges and solid waste collection, and collects additional regulatory fees and permits for industrial waste pretreatment and pollution prevention. Services are delivered via a direct-to-consumer utility model within the district's statutorily exclusive service territory, with 24/7 emergency response and community education channels including a website, newsletter, YouTube content, public tours, and the Recycle Coach sorting tool. The district is governed by an elected Board of Directors, operates a 2024–2034 Strategic Vision plan, and reinvests in infrastructure through a Sewer Pipeline Upgrade program and a 2027 Hazard Mitigation Plan update.

PR NewswireOro Loma Sanitary District Selects Jimmy T. Dang to Lead the District as New General ManagerThe Oro Loma Sanitary District Board has selected Jimmy T. Dang as the new General Manager, effective January 1, 2023, following a national search. Dang previously served as Interim General Manager since July 2022 and held various engineering and management positions at the district since 2011. He stated his goal to continue the district's reputation for innovation and deliver high-quality wastewater and solid waste services to customers in the unincorporated Alameda County communities it serves.PR NewswireGrand Opening of the 1st Full-Scale Sidestream Wastewater Treatment System in the U.S. Western RegionMicrovi announced the grand opening of its first full-scale MNE wastewater treatment system in the U.S. Western Region at the Oro Loma Sanitary District/Castro Valley Water Pollution Control Facility in the San Francisco Bay Area on December 8, 2021. The system, commissioned in late April 2021, converts ammonia to nitrite and nitrate through a proprietary biological process that produces no sludge and uses minimal aeration, achieving nitrogen discharge reduction of up to 400,000 pounds per year. The technology addresses urgent nutrient loading concerns in the San Francisco Bay, which receives some of the highest nitrogen loading of any U.S. estuary, with estimated retrofit costs for Bay Area facilities exceeding $8 billion.PR NewswireOro Loma Sanitary District Input for Disaster PlanningOro Loma Sanitary District in California is taking action to create a Local Hazard Mitigation Plan to prepare for natural disasters and climate change, and has posted a community survey to gather public input on potential hazards such as flooding and earthquakes. The plan, expected to be completed by December 2021, will qualify the District to receive state and federal hazard mitigation and disaster relief funds. The project is being funded through the District's general fund with technical assistance from the City of Hayward, East Bay Regional Park District, Alameda County Flood Control, and Hayward Area Recreation District.PR NewswireOro Loma Sanitary District Launches Strategic Sewer System Improvement ProjectThe Oro Loma Sanitary District Board of Directors has approved low-cost financing to replace approximately 40 miles of aging and defective sewer collection system pipelines over the next five years. The district will utilize pipe bursting technology, which it has refined over a decade, to rehabilitate the infrastructure at the lowest possible cost while minimizing environmental and community disruption. The $240 million project is funded through the Clean Water State Revolving Fund and Water Infrastructure Financing and Innovation Act programs, with the goal of reducing future operational costs and improving system reliability for customers in Unincorporated Alameda County.PR NewswireMicrovi Commissions First Commercial Sidestream Treatment System in the U.S. Pacific Coast Region at Oro Loma/Castro Valley Sanitary Districts' 12 MGD PlantMicrovi and Oro Loma/Castro Valley Sanitary Districts commissioned the first commercial sidestream treatment system in the U.S. Pacific Coast Region at a 12 MGD plant in San Lorenzo, California. The system uses Microvi's MNE technology to reduce nitrogen discharge to the San Francisco Bay by up to 400,000 pounds per year, achieving 25% energy savings and 40% carbon dosing reduction. The project, funded by the EPA and OLSD/CVSan, is expected to reduce the nutrient load by 8,000,000 lbs over 20 years and includes a local internship program for workforce development.PR NewswireOro Loma Sanitary District Commemorates Special Districts WeekThe Oro Loma Sanitary District in California is commemorating Special Districts Week by highlighting its continued essential services during the COVID-19 pandemic, including staggered work shifts, 24/7 sewer operations, and maintained wastewater treatment. The district's board president emphasized these measures ensure vital services continue despite difficult circumstances.

Glaze to BoardThe Oro Loma Sanitary District Board appointed Robert H. Glaze to fill a vacancy created by Director Roland J. Dias's retirement at its October 2, 2018 public meeting. Glaze, a longtime San Leandro resident who retired as Chief Information Officer from the City of Oakland after 40 years of service, brings extensive public service experience including over 15 years on the San Leandro City Council and nearly 20 years as an Alameda County Fire Commissioner.

The project, completed in April 2017 after construction began in 2015, uses vegetation on a gentle slope instead of a vertical wall to absorb wave and storm surges while supporting native wildlife and polishing cleaned wastewater from treatment plants. The district hopes the horizontal levee will serve as a prototype for future large-scale sea rise response projects along coastlines.
