In 2014, Castro Valley Sanitary District (CVSan) heard from residents that many dispose of just one small bag in the brown garbage cart each week.  A recent study found that nearly half the contents of Castro Valley garbage carts can be recycled or composted.

From June-December 2016, CVSan has been conducting a Less Than Weekly Garbage Collection Pilot in a few neighborhoods to help reduce this good stuff being sent to the landfill.  Good stuff such as food scraps decompose in a landfill and release methane gas, which traps heat in the atmosphere.

On December 6, 2016, CVSan mailed postcards to all households that are in the pilot study areas. 

NEW! A final online questionnaire is available here. Please visit the webpage by the deadline of December 31, 2016 and complete the survey to receive a $5 gift card to Starbucks or Pete’s ACE Hardware. Be sure to include your name and address so that we can mail you a gift card.  We value your feedback.

CVSan provided many free tools and resources for pilot households, including a food scrap pail, biodegradable bag liners, and Extra Service Tags during May 16-27, 2016.  Additional biodegradable bag liners were delivered during September 26-30, 2016.

CVSan has created an online space for pilot residents to share with us which tools work well, and which are less successful at

This is an optional pilot that households have been invited to participate in. This project is funded by a grant from Alameda County Waste Management Authority (StopWaste).

The recycling, organics, and garbage trucks will continue to drive by every week. Residents will still have the option of putting their garbage cart out each week.



The pilot program is designed to determine if every other week garbage collection is feasible in Castro Valley and if so, how that might affect future service rates.  We are performing this pilot so that we have that information leading into the next solid waste collection agreement scheduled to be in place in 2019.

Similar studies conducted in Portland, OR, Everett, WA, and currently in Mountain View, CA show that less than weekly garbage pick-ups often increase the recycling of paper, plastic & metal, and composting of food scraps & food-soiled paper.  We’re testing that here in Castro Valley.
