Drain Smart to protect your watershed!

Yes! You read correctly. In this toolkit, Grades of Green has partnered with the City of Long Beach, to help you learn how to “Drain Smart” and how this small action has a big impact on our sewers and watersheds.

This toolkit was created in partnership with the City of Long Beach Utilities:

Toolkit Details

What is a Watershed?

Water that collects on or under an area of land and then flows into a waterway, such as a river, lake, or ocean is called a “watershed”. There are plenty of reactions that happen in the sewers after we flush (yes – the toilet!) or drain and that is why it is important to flush smart so that we can drain smart too!

Launch this toolkit to encourage your classmates, friends, teachers, and parents to limit water pollution and keep our watersheds healthy.

Why It’s Important

Pollution from flushing items that do not belong in our toilets is threatening pipes, sewers, and waterways. The water that we use for our daily activities comes from different bodies of water, but human activities have led to many of them becoming very polluted. Along with pollution, what we flush and put in our sinks can lead to clogged pipes which can cost millions of dollars to repair.

What You Will Accomplish

Students will run a public action Drain Smart campaign to help their school and community keep pipes, sewers, and waterways clean. This will protect the health of their watershed and reduce damage to their wastewater infrastructure in Long Beach.

How does Draining Smart protect Long Beach’s Watershed?

The City of Long Beach currently operates and maintains over 700 miles of sanitary sewer lines, safely collecting and delivering over 40 million gallons of wastewater per day to the Sanitation Districts of Los Angeles County for treatment. There are many levels of ‘treated water’ and ways that it can be reused in a positive manner. Some common ways to reuse and repurpose treated water in Long Beach are to irrigate parks, recharge our groundwater basin, and street sweep. By making sure you are draining water properly, you are helping your city collect and treat wastewater efficiently! Read More Here!

Why Should You Drain Smart

The resources provided below can be shown as a slideshow or printed out as individual worksheets for students to review.

To Flush or Not to Flush?

According to the Responsible Flushing Alliance, 93% of wipes are not meant for flushing down the toilet. These wipes are called non-flushable wipes. They can cause harm to sewer systems and infrastructure because they are made with long, often plastic fibers and are not meant to dissolve in water. That’s why it is important to look at the package and if you see the symbol, toss that wipe in the trash and never the toilet. Non-flushable wipes include all baby wipes, cleaning wipes, disinfecting wipes, and makeup removal wipes, just to name a few. When these products are flushed down our pipes and sewers, they do not decompose and rather, they build up into what we call, fatbergs, which are giant balls of wet wipes and other waste matter that require lots of money to remove from our sewers. Wipes that are specifically called flushable (about 7% of all wipes) are made of short, natural plant-based fibers and are made to dissolve in water like toilet paper. But, if you are unsure of what to do, it is always better to toss a wipe in the trash rather than the toilet. In addition to non-flushable wipes, other items you should never flush down your drains are fats, oils, and grease. (FOG) These substances can also clog the pipes connecting your toilet or sink to the water treatment facility. If you want to learn more about which items should never go down the drain, check out this resource from the City of Long Beach! [1]

Know Before You Go

The Clean Water Act of 1972 just turned 50 years old, yet over 50% of the lakes and rivers in the United States are labeled “impaired”. This means that the water is too polluted for us to swim, drink, or participate in any other fun activity with these water sources. [2] In Long Beach, most of our waters are clean enough for everyone to play and swim in, but these waters need to be tested every week to ensure there are no dangerous pathogens in the waters. All water recreation areas in the city are tested every week for dangerous bacteria and viruses that can make people very sick. Check out more safety tips for recreational swimming in Long Beach’s waters here! Additionally, all storm drains flow to the ocean, so just like the Los Angeles River, anything you toss in these drains, will inevitably get dumped in the ocean and can harm marine life. You can check out health & safety levels for all beaches in your city here! According to the Environmental Protection Agency, 850 billion gallons of raw sewage is dumped into waterways across America every year. This is about the same amount of water the Mississippi River carries into the Gulf of Mexico annually. [3]

Think Before You Drain!

The National Association of Clean Water Agencies (NACWA), states that it costs over $400 million dollars to fix and clean up wastewater treatment equipment when we flush non-flushable wipes in the toilet. If our sewage systems get clogged or leak, it can pollute our groundwater and even flow back into our homes affecting the safety of our community. This is a big problem that can be easily prevented since the Long Beach Reclamation Plant currently treats 18 million gallons of wastewater per day. This issue is worsened by the amount of clogging items being pumped down our drains. There are several other items that should never be flushed or put down a drain. Aside from wet wipes that can create a fatberg, you should never put fats, oils, and grease (FOG) because these materials are not able to break down in water like toilet paper. When we drain and flush smart, we save our water, time, health, and money. [4]

Why Water is a Social Justice Issue?

Millions of people around the world do not have access to safe, clean water for sanitation, drinking, or other activities. All over the world, including in the United States, there are communities that only have polluted water to drink, bathe, and play in, which makes them sick. Typically, this polluted water supply occurs in communities of color and/or lower income communities. Their governments might not have laws or technology in place to protect the health of their environment or they might not hold polluters accountable for the damage they cause. An example of this injustice is in Long Beach where in 2022, a 48-inch sewer main malfunctioned and over 8 million gallons of sewage spilled into the Dominguez Channel and later emptied into Los Angeles Harbor. Due to the overflow of sewage, 7 miles of coastline was shut down in Long Beach due to how dangerous untreated sewage water can be to people who swim in it or ingest it. One of the potential flaws in LA County’s water systems could be attributed to its aging or faulty infrastructure and why there is a need to regularly update these systems to maintain safe and healthy communities of people and natural spaces. Even in places like Long Beach where water municipalities are headstrong, there are instances of people not being able to pay their water bills and having to live with no running water and with concerns of backflow of untreated wastewater.

3. Gather Your Materials and Design Flyers

Before you start protecting your watershed with responsible flushing and draining, you’ll need to start gathering your materials. This can include the following:

  • Pencils, markers, paper, tape
  • Printable flyers on responsible flushing (see resources at the bottom of this toolkit) and protecting your watershed
  • Create your own flyers and call out items that should not be flushed or drained:
    • Non-flushable wipes
    • Paper towels
    • Tissues
    • Cotton Swabs
    • Floss
    • Period  products (tampons and pads)
    • Fat, oil, and grease products (FOG)
    • When in doubt – throw it out!
  • Have “marketer” students create flyers to post around campus announcing your responsible flushing and watershed protections campaign and suggested actions everyone can take.
  • You can use websites like Canva or Google Slides to create your flyers. Include information about the benefits of a healthy watershed and clean water habits.
  • You can also use infographics and slides from this toolkit.
  • Design your own posters – you can even hold an art competition!

4. LAUNCH Your Drain Smart Campaign

It’s time to launch your Drain Smart campaign! Please use the resources below to educate your peers and community about ways to keep pollution out of our waterways. You may use one or all of these: 

  • Have Educator Students walk around campus visiting classrooms to inform other students on the benefits of protecting your watershed and examples of smarter habits to improve water quality. 
  • Pledges – Use a free online platform such as or to collect pledges from Students, Parents, Teachers, and Staff.
  • Post your signs and flyers around campus.
  • Spread Out Your Campaign: Your Campaign can be spread out over the course of one month, one semester, or the whole school year! Depending on what timeline works best for you and your students.
  • Create a Competition: Hold a contest to see which class on campus returns the most parent pledges! Incentivize the winning class with a prize such as a pizza party from a local vendor or gift cards/coupons!

  • Be Sure to be Thankful: Thank your schoolmates, teachers, staff, and parents for helping you keep your waterways clean from pollution.

5. Track Your Impact

At the end of your campaign, use the Drain Smart Tracker to determine the number of water friendly actions you and your community took, including how many people you educated and how many pledged to drain responsibly.
