I don’t receive a bill from Castro Valley Sanitary District (CVSan), do I?

No, you don’t receive a bill from CVSan for solid waste (recycling, organics & garbage) services, because CVSan contracts with Waste Management of Alameda County, Inc. (WMAC) for solid waste services.  You receive a quarterly bill from WMAC.
