Not...Wipes, Diapers, or Feminine Hygiene Products

Please never flush wipes, diapers, or feminine hygiene products, even if they are labeled “flushable.” These products do not disintegrate in water as quickly as toilet paper and often cause clogs in public sewer mains. Put these items in the trash, not the toilet.

See the results when Consumer Reports and the Water Environment Federation tested so-called flushable products. If wipes can clog large sewer mains, they can definitely clog your home’s sewer lateral, requiring you to pay a plumber to clear the blockage.

Not...Medications

Please do not dispose of expired or unused medications in the sink or toilet. Wastewater treatment does not completely remove drugs and traces will end up in the San Francisco Bay. Our community offers many safe disposal options for drugs that protect you, your family, and our waterways.

Combine pills and capsules and seal in a plastic bag. (Recycle the empty bottles in your home recycling cart.) Leave liquids and creams in their original containers (black out personal information) and seal in a plastic bag.

These locations accept both controlled* and non-controlled drugs.

Not...Sharps

Never flush sharps because they can injure wastewater workers. Collect syringes, lancets, and Epi-pens in an approved sharps container (sold at pharmacies and available online). Safe disposal options include:

These options are for home-generated drugs and sharps only. State law requires businesses to use a licensed medical waste hauler.

  • Batteries, fluorescent lights bulbs and tubes, mercury thermometers, and thermostats
  • Solvent-based glue, paint, strippers, wood preservatives, and nail polish
  • Antifreeze, engine cleaners and degreasers, gasoline, and motor oil
