CVSan’s Earth Day 2017 Events

Mon, 04/03/2017 - 10:30am

For many of us, Earth Day is every day.  We work to conserve water and energy, use reusable shopping bags and water bottles, and recycle and compost to reduce what we send to landfill.  Every year Castro Valley Sanitary District (CVSan) hosts an Earth Day Clean-Up and Recycles Day to provide a local opportunity for volunteers to show their spirit.  Save the date for this year’s events on Saturday, April 29th.

Register online at by April 17th to participate in the Earth Day Clean-Up event.  Following a free continental breakfast, clean-ups will be held from 9:00 a.m. to 12:00 p.m. at Adobe Park, Cull Canyon Regional Recreation Area, Castro Valley Creek, Downtown Castro Valley, and Lake Chabot Regional Park. Additional clean-up events will take place at various Castro Valley schools. To register for a school clean-up, contact the school’s main office.

During registration Earth Day volunteers will have the opportunity to select a local charity to receive a $5.00 donation on their behalf.  This year’s charity groups include Castro Valley Sports Foundation, Dusty Paws Rescue, Inc., and Friends of San Lorenzo Creek.  These charities were selected by CVSan’s Community Advisory Committee, a ten-member volunteer group that represents the community’s interests by providing a voice directly to the CVSan Board of Directors.

The Recycles Day event will be held at Canyon Middle School from 8:00 a.m. to 2:00 p.m. for CVSan customers.  E-waste, used cooking oil, documents for shredding, and mattresses will be accepted. For a complete list of accepted items, visit Recycles Day participants can also receive three free bags of compost and a Construction & Demolition Voucher to drop off two cubic yards of materials at the Davis Street Transfer Station. Compost and vouchers will be distributed on a first come, first served basis.

CVSan Holds Second Annual Zero Waste Week for the Community

Thu, 02/09/2017 - 12:42pm

To help Castro Valley Sanitary District (CVSan) residents learn more about how to select their path to zero waste, CVSan presented the second annual Zero Waste Week (formerly entitled Commitment to Serve Week) to the Castro Valley community from Tuesday, January 17th to Saturday, January 21st

To kick off Zero Waste Week, CVSan installed the Museum of Bad Design at the Castro Valley Library.  This display showcases one-time use products that are harmful to the environment alongside reusable products that can be used instead.  The display is still available at the Library for viewing.

On Thursday CVSan hosted its first ever multilingual event – a Food Scrap Recycling Workshop in English, Cantonese, and Mandarin at the Palomares Hills Clubhouse. This event was presented in partnership with Pamela Evans, member of the Palomares Hills HOA Green Team. Approximately 30 attendees took home food scrap recycling pails and tips to help them compost at home.  Additionally on Thursday and Friday, CVSan collected clothing and shoe donations for Goodwill Industries.

CVSan hosted two events on Saturday, a screening of the movie, Clean Bin Project, and a Fixit Clinic at the Castro Valley Library. Twelve volunteer coaches (five from Castro Valley) were on-hand at the Fixit Clinic to help participants learn how to fix their broken items such as a paper shredder, belt sander, and electronics. 74 percent of the items were repaired and approximately 100 lbs. of potential waste was diverted from the landfill.   A special thank you to the five Castro Valley coaches: Dave Coleman, Charles Glorioso, Sarah Foster-Peck, Mike Barbaro, and Ron Eversole for donating their time!

CVSan Experiences No Sewer Overflows during January Rainstorms

Fri, 02/03/2017 - 9:22am

Despite increased rainfall in January, Castro Valley Sanitary District (CVSan) did not experience any sanitary sewer overflows (SSO). Castro Valley received 6.79 inches of rain during January, including 1.95 inches on January 10th alone. In comparison, Castro Valley received 5.25 inches during January 2016 and no rainfall during January 2015.

Achieving no SSOs during large rainstorms show that CVSan’s sewer system is performing well, and that continued maintenance has been an effective proactive measure. CVSan has continued to be SSO-free for over ten months, ensuring that local creeks and Lake Chabot remain free of unwanted sewage.
