    Castro Valley Sanitary District (CVSan) hosted its 12th annual Earth Day Clean-Up event in April 2014.  For the third year in a row, CVSan provided each volunteer an opportunity to select 1 of 3 local charities to receive $5.00 on their behalf.  CVSan is proudly donating a total of $1,635.00 to local charity groups based on each volunteer’s selection. 

    Kiwanis representative, Bill Mulgrew, attended CVSan’s July Board meeting and was presented with a donation of $275.00.  Mr. Mulgrew thanked CVSan’s Board of Directors for their generous donation.  He shared the donation will go towards two of the causes supported by Kiwanis Hayward-Castro Valley Chapter.  Kiwanis International is working to eradicate neo-natal tetanus in partnership with UNICEF.  There are 24 countries left with this disease and every 9 minutes a baby dies from it.  Additionally, the Kiwanis Hayward-Castro Valley Chapter plans to assist Castro Valley Relay for Life who hosts a hot breakfast for approximately 150 volunteers.

    The Castro Valley Sanitary District (CVSan) has acquired the California Department of Transportation (CalTrans) property near the intersection of Castro Valley Blvd. and Center Street.  This property was surplused by the State of California.  CVSan purchased the 73,000 square feet site for $1,500,000.

    “This property is almost three times the size of CVSan’s current offices and can offer many opportunities for more efficient operations in the future” said General Manager Roland Williams.

    CVSan could benefit from the following:

    • Consolidated operations at one site.
    • Purchased property below market value.
    • Beautification of a blighted and underutilized area in Castro Valley.

    The site will be integral in CVSan’s long-term strategic plans.

    School Custodians go out of their way to help schools reduce waste.  Schools in Castro Valley have high recycling and composting or “diversion” rates (average 76%) in large part due to the efforts of custodians.  Castro Valley Sanitary District (CVSan) recognized school custodians during the 3rd CVSan Custodian Recognition Luncheon at Canyon Middle School on Tuesday, June 17, 2014.  All Castro Valley School Custodians and School Administration were invited.   

    Awards were given out to the following Custodians:

    • The Dan Curry Custodian Program of the Year Award:Tim DeForest of Creekside Middle School (see photo below).

    “Helping schools reduce the amount of waste sent to landfill and educating students about recycling and composting are important parts of our mission at CVSan.  Without the dedication and support from school custodians, we wouldn’t be where we are today—recycling and composting 76% of what used to be thrown away as garbage,” said General Manager, Roland Williams.

    Castro Valley Sanitary District (CVSan) is pleased to announce the two winners of the 2013/14 CVSan Environmental Leader in Waste Reduction Scholarship: Madeline Hahn and Suzanna Chak.  This is the first year CVSan offered the scholarship to high school seniors.  The scholarship is a way to recognize those students who are taking action and encouraging environmental awareness through waste reduction within their school and community. 

    The two scholarship winners were invited to CVSan’s Board of Directors meeting on May 6, 2014.  Environmental leadership was demonstrated by the scholarship winners through participation in CVSan’s Community Advisory Committee and participation in environmental clubs at Castro Valley High School.  Madeline Hahn described the motivation to become an environmental leader in her essay:

    I don’t think I even realized how much of an impact each person has on our environment until I attended a Davis Street Transfer Station tour sponsored by the Castro Valley Sanitary District.  We looked at compost, recycling, clothes, but the image that stuck with me the most was looking into the massive warehouse full of “trash”.  Things that weren’t put into the recycling or compost. I then imagined almost half of the “trash” in there disappearing.  It could’ve turned into mulch to grow plants or trees to grow paper.  The possibilities are endless for each small act of environmental awareness.

    CVSan’s Environmental Leader in Waste Reduction Scholarship award winners each receive a $500 scholarship.  Please see below for photos from the May 6th Board Meeting:

    The Castro Valley Sanitary District (CVSan) is pleased to report that Stacy Marcoux, Administrative Assistant, completed the California Special Districts Association’s (CSDA) Board Secretary/Clerk Certificate Program. 

    The board secretary/clerk in a special district plays a multi-faceted role that is also one of the most highly visible in CVSan. Board members, the public and staff turn to the board secretary/clerk as a resource for information and assistance. In addition, the board secretary/clerk must understand CVSan’s extensive legal requirements, handle a wide variety of situations, respond to the needs of board members and the public, and document board activities and decisions.

    This certificate program was developed by CSDA in order to expand educational opportunities for individuals who hold this important position in special districts. The Board Secretary/Clerk Certificate Program recognizes individuals who invest the time in becoming trained in the various components of this essential and often complex job.

    In order to become certified under the program, Stacy Marcoux attended two workshops developed specifically by CSDA for board secretaries/clerks, and four elective webinars covering topics ranging from proper records retention and management to how to assist in running an effective board meeting to understanding board member and district liability issues.

    This specially designed CSDA program is an excellent opportunity for board secretaries/clerks to further their education, gain a better understanding of the role they play in their special district and discuss issues important to the effective performance of a board secretary/clerk.

    Congratulations to Redwood High School for completing Redwood’s first waste audit! Organized by high school counselor, Ninah Asuncion, the audit was conducted as part of CVSan’s Green Ribbon Schools Program. The waste audit helped identify how well Redwood students and staff are recycling and composting, and highlighted which areas could be improved upon. 

    The waste audit was held after school on Wednesday, February 5, 2014. Three students volunteered their time to sort through one day’s worth of garbage - 28.5 gallons!

    The results of the waste audit showed that 33% of the materials sorted in the waste audit was actual garbage. Recyclable materials made up 50% of materials sorted and the remaining 17% was compostable material. Considering that Redwood’s food scrap recycling (organics) program began nine months ago, the waste audit results show that students and staff are doing a great job sorting their organics materials! Ongoing improvements to the organics and recycling programs at Redwood will surely further waste reduction for the school.

    Great job Redwood High School for committing to see what’s in the garbage and continuing to reduce waste at school!  A special thank you goes to Ninah Asuncion, Dan Poulos, and the three students for a successful waste audit!

    Below are a few photos of the day’s activities.

    Most businesses in Castro Valley generate at least a small amount of organics to make service worth the small effort but restaurants and schools have even more organics than garbage!  With food scraps, food-soiled paper, and paper towels or facial tissues, there are plenty of opportunities to collect organics and save money. Now over 100 businesses in Castro Valley are saving with organics!

    How do businesses that participate in organics save money?  In CVSan, collection rates for organics cart service are less than the cost of garbage cart service, which adds up to a lot of savings. To reward businesses for their efforts to participate in organics collection, CVSan implemented the 4R Business, 4R Planet Recognition Program in 2009 to certify 4R Star businesses that complete activities in each of the 4R categories.  Those categories are more simple than you might think: Reduce (buy less, buy in bulk, etc.), Reuse (use reusable utensils or cups, etc.), Recycle, and Rot (organics).  

    Certified businesses receive a cash award up to $525!  Over 70 businesses have now been certified and received their 4R Star award and recognition.  For more information, please visit our website at  Go to the complete directory of 4R Stars in Castro Valley.  To inquire about starting organics service, contact CVSan at (510) 537-0757. 


    The Burrito Shop (shown above) has been a CVSan 4R Star since May 2013 and customers and staff participate in the recycling and organics programs every day.
