“This is the first time Central San has hosted a public Open House like this, and we’re very excited,” said our General Manager, Roger Bailey. “In addition to commemorating our 70 years of service and showing people what we do, the Open House is a way for us to thank our customers for their support. Whenever they prevent grease from going down the kitchen sink, put disposable wipes in the trash instead of the toilet, or bring chemicals and other hazardous wastes to our collection facility rather than pouring them down the drain, they are helping us to protect public health and the environment. We couldn’t accomplish our mission without their assistance, and we want to show our appreciation by inviting them to our ‘house’ to have a great time and learn more about the services we provide.”

PLEASE NOTE: Our Household Hazardous Waste Collection Facility and Residential Recycled Water Fill Station will NOT be open for business on July 16 due to the Open House. However, attendees will be able to get a rare behind-the-scenes look inside the HHW Facility to discover what really happens to all the materials people bring in for disposal!

The Open House is sure to be a hit with the whole family!

Truck displays
Kids of all ages love our big truck displays!

If you go to the Open House and post pictures of it on Facebook or Twitter, please use #CentralSan70th. You might even win a prize! We’ll randomly select five posters who use that hashtag to receive a cute toilet mug! 

See you on July 16!

Sewer Construction in Your Neighborhood?

Here’s What to Expect

Sewer construction

The single largest asset of the Central Contra Costa Sanitary District is our sewer system, which consists of 1,500 miles of pipes and transports millions of gallons of wastewater every day to our treatment facility in Martinez.

Maintaining this huge system to ensure reliable service for our customers requires construction projects to renovate or replace aging pipes. Since these pipes spread throughout our entire service area, this activity is bound to have an impact on our residential and business customers.

Here’s how we communicate with customers who are likely to be affected by the construction:

Before Construction

• Nine-to-twelve months before construction activities begin, we mail letters notifying people of design activities that will be taking place in their area over the next several months. These activities include marking utility and sewer locations, surveying, and inspecting the area in order to draw up the best construction plan for the project.

• Once we have that plan, if work will be required within easements on private property, we contact those customers individually to discuss the construction and restoration activities.

• As the project nears the bidding phase, we invite all customers in the project area to a public meeting where we share our plan, answer questions, and discuss any issues of concern so we can make changes to the plan, if appropriate.

• Once the project is awarded to a contractor, we send another letter to all customers in the project area announcing when construction is expected to begin and end. A typical project can last six-to-nine months.

• As the project progresses, the contractor notifies customers one week in advance of any construction in their neighborhood.

• Signs are posted in the area which include the project duration and a contact number to call for more information.

Sewer Construction

During Construction

• During construction, one of our inspectors will be on-site to monitor the project and ensure the contractor is meeting our specifications. This includes not only the specifics of pipe installation, but also safety, cleanliness, traffic control, and property restoration.

• Customers with questions or concerns about the project can approach the on-site inspector or call our Community Affairs Representative, Chris Carpenter, at (925) 229-7200.

After Construction

• Once the project is complete, we send a survey to all customers in that area. This survey provides us with valuable feedback: people can make us aware of any issues that may have been overlooked, and let us know how they felt the project was handled. The questions cover the courtesy and responsiveness of staff, timeliness of notices, traffic impacts, and how promptly issues were resolved. Each item is rated on a scale of one to five, with five being outstanding. To date, we are maintaining an average four-plus rating for all aspects on all projects.

We understand that construction can cause inconveniences for our customers. We will continue to keep you informed of work in your neighborhood, and design projects to reduce the negative impacts where possible, all while maintaining a reliable and effective sewer system that protects public health and the environment.

You can find information about current construction projects, including project maps, at — click on “Construction Zone” in the lower right of the home page.

How to Bring Items to Our HHW Facility

Planning to bring items to our Household Hazardous Waste Collection Facility? Here’s how to have a safe trip.

HHW Packing
Pack your items carefully before transporting them to the facility.

Are you planning to bring paint, batteries, bleach, cleansers, motor oil, pesticides, fluorescent bulbs or other items to our Household Hazardous Waste Collection Facility? First, think about that word, “hazardous.” Now think about the interior of your vehicle. Think about you being inside the vehicle with something hazardous… driving on roads shared by people who might be distracted.

Frightened? Don’t be! The last thing we want to do is scare you away from using our facility!

But we DO want you to be careful about how you pack and transport the items you bring. Check out this video, and/or read the tips below.

Here’s how to SAFELY transport household hazardous waste to our facility:

NOTE: State regulations limit the transportation of hazardous waste to 15 gallons or 125 pounds per trip, and individual containers are limited to 5-gallon capacity.

• Get a cardboard box (or plastic bin) sturdy enough to support the weight of the contents. Reinforce the bottom of the cardboard box with tape.

• Line the box with a plastic garbage bag (to catch spills). Fold the flaps of the box inward, place the bag inside the box, and drape it over the sides. Do NOT close the bag (our staff need to easily see what’s inside).

• Make sure all items you’ll be bringing to the facility have tightly closed lids. NEVER transport open containers!

• Keep items in their original packaging, if possible – especially with easily breakable items like fluorescent light bulbs. If you don’t have the original packaging for fluorescent bulbs or tubes, wrap a rubber band around them to keep them from rolling around in your vehicle.

• If an item is leaking, seal it within a Ziploc-style plastic bag.

• Place the items inside the lined box.

• Pack mercury-containing items (fever thermometers, thermostats, fluorescent light bulbs) carefully and keep them separate from other items that might break them if jostled.

• Put the box in your trunk or truck bed – never inside the passenger cabin. Secure the box to prevent movement.

• Drive to the facility and let our friendly staff remove your items while you remain comfortable inside your vehicle.

It really is worth the effort. Bringing your household hazardous waste to our facility helps to keep harmful materials out of our local waters and landfills.

There is no drop-off fee and no appointment necessary for residents of central Contra Costa County. Small businesses require an appointment and are charged a nominal fee.

Please call  1-800-646-1431 or view our Household Hazardous Waste Facility page for more information.

Sewer Facts vs. Fiction

Can you separate fact from fiction when it comes to what’s good — and bad — for sewers? Here’s a list that will increase your sewer IQ, and possibly help you to avoid an expensive plumbing bill!


Containers for Recycled Water

If you are interested in getting free recycled water from our Recycled Water Fill Station, you have to bring your own containers. The maximum fill per trip is 300 gallons. There is no limit on number of trips.

Container requirements:

  • Must be a minimum size of one gallon
  • Must be specifically designed to hold liquids (e.g., no trash barrels!)
  • Must have watertight lids
  • Must be secured for safe transport

Central San does not endorse any particular brand of container, but here are some ideas (not to scale):

275-Gallon Tote
275-Gallon Tote


55-Gallon Drum
55-Gallon Drum


7.5-Gallon Container
7.5-Gallon Container


5-Gallon Container
5-Gallon Container


1-Gallon Container
1-Gal. Container

Please Note: Water is heavy! Ten gallons weigh more than 80 pounds; 100 gallons weigh more than 800 pounds. When driving vehicles with such heavy loads, expect less stability and be sure to allow for additional stopping distance.

We do not sell containers. Depending on your needs, you may be able to find something at a local hardware store. Many people have also used Craigslist, EBay, and Amazon to find containers.


Keep Your Butts Out of the Bay

Cigarette butts are the most common item of trash collected during beach clean-up events. They also comprise an estimated 30-50% of all trash collected from roads and streets.

But they’re more than just a litter problem. When you throw cigarette butts on the ground or flush them down your toilet, you’re polluting the Bay.

cigarette butt pollution
Please keep your butts out of the Bay!

When butts are dropped on sidewalks, parking lots, streets or into gutters, they are often swept down storm drains with rain or irrigation runoff. Our storm drains flow untreated into local creeks and the Bay.

When you flush butts down the toilet, they travel through sewers to the wastewater treatment plant. Treatment plants are designed to remove human biological wastes. They cannot remove all traces of toxic chemicals.

Yes, cigarette butts are loaded with toxic chemicals!

The purpose of a cigarette butt (filter) is to trap the toxic chemicals created in the smoke when the cigarette burns. Nicotine is the chemical most people associate with cigarettes, but that’s only one of the toxins captured by the filter. “Tar” refers to more than 3,500 chemical particles (including arsenic, vinyl chloride, benzene, hydrogen cyanide, mercury and lead) generated by a burning cigarette.

Those toxic chemicals, many of which are especially lethal to aquatic life, leach out of the butts when exposed to water.

But that’s not the only problem with cigarette butts. Most are made of cellulose acetate, a form of plastic. Plastic is not biodegradable, but it does eventually break down into small pieces. Fish and birds mistake these pieces for food and eat them, often with fatal consequences and long-lasting damage to the ecosystem.

This is one type of pollution that is easily preventable.

If you smoke, please dispose of your butts properly. Don’t throw them on the ground. Don’t flush them.

Otherwise, that little flick of your wrist can do serious harm to our water environment.

Grease is Gross! (Especially for Sewers)

If you do this:

Please don’t do this:

Never pour grease down the drain
Never pour grease down the drain!

Pouring grease down the drain is one of the worst things you can do to your home’s plumbing — and the public sewers.

Some people think it “goes away” when they wash it down the drain with hot water. It doesn’t. Grease quickly cools, hardens, and then clings to the inside of pipes. It forms a gross, sticky blob that grows over time. Eventually the pipe can become totally clogged, and sewage can backup and overflow in your home, or in the streets.

Instead of pouring it down the drain, put cooled grease (and fatty food scraps and used cooking oil) into a disposable lidded container. Store it in the freezer to harden, and then put it in the trash.

Bring large quantities of grease and oil (such as from a turkey fryer) to the Household Hazardous Waste Collection Facility for recycling into biofuels.

The Scoop on Pet Poop

puppy and kitten

We know they’re cute. They’re loyal and loving, and who can resist those adorable furry faces? But there’s another side to cuddly cats and dogs: the back side that produces poop pollution!

From Your Lawn to the Bay

According to the EPA, pet waste is a significant cause of water pollution.

When left on the ground, pet waste can be washed by water from sprinklers and rain into gutters and storm drains. Storm drains in our area are not connected to the sewer system; they funnel water directly into creeks, streams and the bay without treatment.

In water, the bacteria in decaying pet waste consume oxygen and release ammonia. Low oxygen levels and ammonia can be harmful to aquatic life. Pet waste also contains nutrients that promote excessive weed and algae growth, making water cloudy, green, and unhealthy.

Perhaps most importantly, pet waste contains bacteria, viruses and parasites that can make water unsafe for swimming or drinking.

The Solution Is As Simple as 1, 2, 3

It’s easy to prevent pet poop from polluting our water environment. Just follow these three steps:

1. Pick it up
2. Put it in a bag
3. Put it in the trash (never in the yard waste or compost bins!)

Landfills are designed to handle that type of waste.

Can You Flush It?

Please do NOT flush pet waste.

• Out treatment plant was designed to serve the human population of central Contra Costa County, not accounting for pets. Right now there are nearly 470,000 people in our service area. We don’t know the pet population, but if 50% of our customers have one pet, that’s about 235,000 additional little (or big) poopers. If all that pet waste were to be flushed, it would put an additional load on our system and could make it more difficult for our treatment plant to treat the human waste for which it was designed.

• Please do not flush Flush Puppies® or other brands of “flushable” dog poop bags. They may be biodegradable, but that doesn’t mean they dissolve quickly in water (one manufacturer admits this can take up to 96 hours). Even though they go down your toilet, they can clog sewer pipes!

What About Flushing Kitty Litter?


Typical kitty litter is made of clay. Clay mixed with water makes something close to cement which can clog your pipes. Even if it isn’t made of clay, nearly all litter is designed to absorb liquid, and when that happens, the particles expand; your pipes don’t. “Flushable” kitty litter may be more biodegradable, but can still clog your pipes. Sewer (and septic) systems just aren’t designed to handle kitty litter, no matter what it’s made of.

Aside from the litter itself, what’s in the litter – cat poop – may contain the Toxoplasma gondii parasite, which can survive the treatment process and is known to kill marine mammals like sea otters. That’s why all cat litter sold in California is required to have a label warning people not to flush it down the toilet.

Put the litter into a bag, seal it, and put it in the trash.

How to Make Greener Cleaners

Winter is over, and for many homeowners that means it’s time for spring cleaning. Unfortunately, many cleaning products contain metals, solvents, and toxic chemicals. If poured down your drain, these can pollute Suisun Bay because our wastewater treatment process is designed to treat biological wastes; it cannot remove all traces of those pollutants before the treated water flows into the Bay.

Many cleaners also contain unnecessary antibacterial agents (which are technically pesticides) that can make bacteria more resistant to antibacterial drugs!

But don’t worry, we have alternatives for you that use baking soda, borax, lemon juice and other ingredients that are friendlier to our water environment. These homemade solutions are also less expensive than commercial cleaning products.

Natural cleaners
Natural DIY cleaners are safer for the environment and easier on your wallet!

All-purpose cleaner: Baking soda mixed with a little water (paste consistency). For stubborn stains, work it in and let it sit for a while before you remove with a damp cloth or sponge.

Disinfectant: Full-strength white distilled vinegar. Spray or rub on surfaces, door knobs, etc. Alternative: ½ cup Borax in 1 gallon hot water.

Drain cleaner: Baking soda, salt, vinegar, boiling water. Pour ½ cup baking soda and ¼ cup salt into drain, add ½ cup vinegar, cover drain while fizzing (let sit overnight for best results), then flush with boiling water. To clear clogs, use a Zip-It drain cleaning tool, plumber’s snake, or plunger. Note: Do NOT use the baking soda combination or a plunger after using a commercial drain opener. Tip: To avoid clogs, use drain strainers to trap food particles and hair; collect grease in cans rather than pouring it down the drain.

Glass cleaner: 2 cups water, 1 cup white distilled vinegar and 1 teaspoon liquid soap or detergent. Put in spray bottle; use to remove wax residue left by commercial window cleaners. After that residue is removed, you can leave out the soap for future cleaning. Alternative: lemon juice and water. Tip: Wiping with newspaper instead of paper towels prevents streaks.

Grease remover: Lemon juice or vinegar. Spray or douse, let sit a few minutes, then scrub.

Lime & mineral deposit remover: Vinegar and paper towels. Hard lime deposits around faucets can be softened for easy removal by covering the deposits with vinegar-soaked paper towels. Leave paper towels on for one hour before cleaning.

Mildew remover: Undiluted white distilled vinegar. Use it on a cloth or sponge mop to wipe down surfaces.

Oven cleaner: Baking soda and very fine steel wool. Sprinkle water followed by a layer of baking soda. Let stand overnight. Rub gently with a very fine steel wool pad. Wipe off scum with dry paper towels or sponge. Rinse well and wipe dry.

Scuffmark/watermark remover: Toothpaste. Use to remove scuffmarks from floors and watermarks from wood furniture.

Now that you’ll be using these homemade alternatives, you can dispose of your unwanted commercial cleansers (as well as paint, pesticides, batteries, solvents, cleansers, and other potentially hazardous household products) free of charge at our Household Hazardous Waste Collection Facility. Never put them down the drain or in the trash.
