  2. Before visiting the HHW facility, place your waste in the trunk or hatchback of your vehicle or the bed of your truck. HHW staff will not collect waste that is in the front or back seat.
  3. Face coverings and social distancing are required at all times while visiting the HHW facility, including while you are in your vehicle.
  4. HHW staff will retrieve the waste from your vehicle. Please remain in your vehicle unless staff ask you to exit the vehicle to open or close the trunk or tailgate. 

The Solution to Pollution

In 1997, Central San and Mt. View Sanitary District teamed up to build the first permanent Household Hazardous Waste (HHW) Collection Facility in the county. Residents may drop off household hazardous waste at no charge. Small businesses pay a small fee to dispose of their hazardous waste. In its first 20 years, the facility collected more than 36 million pounds of hazardous waste.

Hazardous waste generated by residents and businesses can reach our waterways through runoff, sanitary sewers, storm drains, landfills, and can pollute our local water environment. The Household Hazardous Waste Collection Facility helps prevent this pollution through reuse, recycling, and proper disposal of hazardous waste.

  • Central San teamed up with Mt. View Sanitary District (MVSD) in 1997 to build and operate the first permanent Household Hazardous Waste (HHW) Collection Facility in Contra Costa County.
  • The HHW Collection Facility is located adjacent to Central San wastewater treatment plant in Martinez, west of Solano Way from Highway 4.
  • In its first 10 years, the HHW Collection facility kept more than 16 million pounds of hazardous waste out of the environment. 
  • Hazardous waste generated from households in the central Contra Costa County area is accepted at no charge upon drop-off.
  • Small businesses are charged an administration fee of $20 and a nominal disposal fee, based on the type and quantity of waste to be disposed. For more information take a look at our Small Business Brochure or call 1-800-646-1431.
  • To keep hazardous waste disposal to a minimum, and to assure products are used up as they were intended, the HHW Collection Facility offers a Reuse Program that allows residents and businesses to take usable products, for example, paint, automotive products, and household cleaners at no charge. 
  • To help “close the recycling loop,” the facility was constructed by using materials containing recycled content — such as newspapers, plastic, and glass — from community recycling programs.

Fats, Oils and Grease (FOG)
How to Prevent FOG from Damaging Your Home and the Environment

Fats, Oils and Grease (FOG)

Fats, oils, and grease aren’t just bad for your arteries and your waistline; they’re bad for sewers too.

Sewer overflows and backups can cause health hazards, damage home interiors, and threaten the environment.

The second leading cause of all sewer overflows is grease blockages. Grease can get into the sewer from household drains as well as from poorly maintained grease traps in restaurants and other businesses.
