Castro Valley Sanitary District single-family residents (4 units or less) are eligible to receive a $50.00 credit on their next recycling & garbage bill by reducing their waste and garbage cart down to a 20-gallon.  Residents, on their honor, are encouraged to commit to the smallest garbage cart for at least a year. 

Bill payers may now request a downsize by calling the (510) 613-8745 message center with required account information or by completing the online form.  Cart exchanges will be scheduled by appointment.  Read on or call (510) 537-5500 for program details, eligibility guidelines, and the required account information to be left on the message center.

By reducing your garbage cart to a 20-gallon, you will be:

• “Right-sizing” your garbage cart to better represent what you actually send to landfill.

• Saving approximately $12.00 per month on your bill, or $144.00 per year (per 32 to 20-gallon cart migration).  Your next bill will be prorated from the date your request was confirmed with Waste Management of Alameda County, Inc. (WMAC).

• Receiving a $50.00 credit on your next WMAC bill.
