To the City of Palo Alto Regional Water Quality Control Plant and the Household Hazardous Waste Station.
You can help protect San Francisco Bay and local creeks every time you use a drop of water in or around your home.
Pool party! We love to swim and my family loves the Bay. We clean and maintain our pool so that water and pool chemicals stay out of stormdrains because they carry water right into our creeks and Bay.
Cars make air and water pollution so keep your car in good shape. Have it serviced at a Clean Bay Business autoshop.
Less is better when it comes to household chemicals. We avoid buying too many cleaners, pesticides and other chemicals. When we have something to get rid of we bring it to the Palo Alto Household Hazardous Waste Station.
Pesticides don't belong on kids, pets or in our creeks. Here's what local pest pros say to control ants and garden pests.
Toilets are not trashcans! Cotton swabs, dental floss, cat litter, wet wipes, sanitary products, and toys should not be flushed— even if the packaging says it’s okay. They can cause sewer backups into your house, onto streets or into creeks. See what Consumer Reports say about this!
When we clean out our medicine cabinet we bring unwanted medications to a drop off location in town. We never flush them down sinks or toilets or put them in the trash.
Microbeads are tiny bits of plastic that make thier way into the Bay from wind or wastewater. We don't need them and neither does the Bay so avoid soaps and shampoos that list plastic microbeads as an ingredient (look for ingredients labeled polyethylene or polypropylene. Learn more about microplastic pollution in the Bay.
My mom's a doctor and she keeps antibacterial soap and other antibacterial products out of our house because they're not healthy for people or the Bay.
Have you ever cleaned up a sink that's backed up into your kitchen? Not fun!! Keep grease and oil out of the sink (pour it into a can), send kitchen scraps to the compost or garbage, and recycle large amounts of cooking oil and grease.
Creek critters die in chlorinated water! Drain pools and fountains to a sanitary sewer cleanout and never to storm drains which lead to creeks.
Water used in and around homes in the RWQCP service area travels to San Francisco Bay. Sink, shower, and toilet water travels to the RWQCP for wastewater treatment where biological wastes are removed. Stormwater travels to creeks and the Bay without treatment.

No Drugs Down the Drain
U.S. Geological Survey studies have found hormone medications, antidepressants and antibiotics in San Francisco Bay coming from the disposal of unwanted drugs down sinks and toilets, and from human waste. Sewage treatment plants are not designed to remove all the substances contained in medications.
Next time you need to wash your hands, use soap instead of antibacterial products that contain triclosan or triclocarban. Triclosan is a registered pesticide and an emerging pollutant of concern in San Francisco Bay. Triclosan and other antibacterial agents are found throughout the environment in surface water, soil, fish tissue, and effluent (cleaned and treated wastewater discharged to the Bay).
The American Medical Association advises that people wash their hands for at least 20 seconds with soap (without antibacterial products) to remove germs. Avoid using personal care products containing triclosan or triclocarban listed on the label as an "active ingredient." Common products where triclosan is found include make-up, toothpaste, lotions, skin creams, deodorants, sanitizers and wipes. It is also found in toys, kitchen tools, sports equipment and athletic clothing.

Reduce Plastics in Our Creeks and San Francisco Bay
Plastic comprises 60% of the litter found in Santa Clara County creeks. Plastic bags, plastic foam products (such as Styrofoam™), beverage containers, and other plastic debris are carried by wind and storm drains into creeks, the Bay and Pacific Ocean.
Here's how you can help reduce plastics in our waterways:
- Use reusable shopping bags for all grocery store and retail shopping
- Use reusable water bottles and travel mugs
- Request that your local newspaper carrier use a plastic bag only when it rains.
- Learn more at plasticfreeguide.com
Palo Alto prohibits the use single-use plastic checkout bags and plastic foam products or packaging at all Palo Alto retailers and restaurants. For more information:
Less-Toxic Pest Control
Residential pesticide use by homeowners and pest control services is the main source of pesticide pollution in San Francisco Bay. Spray pesticides used for ant control are one of the largest contributors. These and other pesticides wash into storm drains and creeks during rain or when you water your garden.

Toilets Are Not Trashcans
The label on the baby wipes and kitty litter package claims that it's "Flushable," but is it really? Since cotton balls break apart, are they ok to flush down a toilet? None of these items should be flushed down a toilet.
"Flushable" wipes are usually made from plastic resins, don't disintegrate like toilet paper, and contribute to costly sewage back-ups. These can be harmful to the environment if the overflow reaches the street's storm drain. Cotton balls become soggy and get trapped in the pipes, causing serious backups as well. Only three things should be flushed: water, human waste and toilet paper!
Other items that should never be flushed:
- Hazardous wastes such as medications, paints, chemicals, pesticides and fertilizers
- Dental floss & band aids
- Kitty litter
- Feminine hygiene products
- Cooking grease and oil
- Cigarette butts
- Paper towels
- Disposable diapers
- All types of wipes including cosmetic, cleaning, "disposable" and "natural" types
Fats, Oils and Grease
Pouring fats, oils and grease (FOG) into the sanitary sewer system is an environmental and public health issue. FOG builds up in sewer lines and clogs pipes causing backups and raw sewage overflows onto streets, storm drains, and creeks.
To prevent sewer backups:
- Never pour grease down sink drains or into toilets.
- Scrape grease and food scraps from trays, plates, pots, pans, utensils, and grills and cooking surfaces into a can or the trash for disposal (or recycling where available).
- Don't pour grease or cooking oil down garbage disposals. Put baskets/strainers in sink drains to catch food scraps and other. solids, and empty the drain baskets/strainers into the trash for disposal.
Maintaining your pool, spa or fountain
- Clean regularly and maintain proper chlorine levels.
- Never clean pool filters in the street, gutter or storm drain.
- Rinse cartridge filter onto a dirt area and spade filter residue into the soil. Backwash sand and diatomaceous earth filters onto a dirt area. Keep backwash discharges out of the street and storm drain. Dispose of spent filter materials in the trash.
- Test water frequently and adjust the pH, total alkalinity, hardness and dissolved solid levels as recommended by your pool manufacturer. This is extra important during warm weather or heavy pool use.
- Ask your pool maintenance service to use an alternative to copper algaecides such as:
- Polymeric algaecide
- Sodium bromide
- Chlorine or chlorine-enhancers
- Hypochloritecontaining shock treatments
- If draining your pool is necessary, discharge the water to a sanitary sewer cleanout (never street, or stormdrain).The sewer line clean-out is usually located in the front landscaped area or near the sidewalk, and marked with an "S". The clean-out will have a small circular cap. How to find your clean-out.
- For septic systems, contact Palo Alto Water Quality Control Plant 329.2598.
Dumping sewage and/or wastewater from recreational vehicles onto streets or storm drains is illegal and harmful to public health and to the environment.
