CVSan Recognizes Castro Valley High School Custodians with Award

School Custodians go above and beyond to help schools reduce waste. Schools in Castro Valley have high recycling and composting, or “diversion” rates, in large part due to the efforts of custodians. Castro Valley Sanitary District (CVSan) recently recognized school custodians with its Ninth Annual CVSan Custodian Recognition. This year, the Dan Curry Custodian Program of the Year Award was given out to the custodial team at Castro Valley High School (CVHS).
