This animated video series is perfect for K-8th graders, and explains the cycle of water as we follow one rain drop, Dotty, from her formation as a rain drop to her journey through the wastewater treatment plant and back out to sea.


Water is 4 Billion Years Old!

Dotty introduces the series brought to you by the Wastewater Agencies of Marin County, and lets kids know what they will learn about.

Runtime: 1 minute 40 seconds
Format: YouTube HD 1080p or Standard

Ever Wonder Where the Water Goes?

Dotty describes where the dirty water goes once it leaves your home. Of course, it goes to the Wastewater Treatment Plant!

Runtime: 1 minute 20 seconds
Format: YouTube HD 1080p or Standard

Getting the Big Stuff Out

Tommy the toilet paper roll describes Primary Treatment--the process that first removes the big things that end up in the treatment system.

Runtime: 2 minutes 15 seconds
Format: YouTube HD 1080p or Standard

Good Eating for Bugs

Dotty shows how good bacteria (a.k.a. bugs) eat the waste when provided with oxygen in the water. Secondary Clarifiers then push the sludge to the bottom of the tank where it is removed. Finally, disinfecting takes place to finish the job!

Runtime: 2 minutes 25 seconds
Format: YouTube HD 1080p or Standard

Storm Drains are Different from Sewers

Dotty illustrates how the storm drains and your sewer system are not the same. Sewage is treated at the water treatment plant while storm water goes directly into the creeks, bays and oceans--and both must be kept clean!

Runtime: 1 minute 20 seconds
Format: YouTube HD 1080p or Standard

Let's Stop Water Pollution

You can help reduce pollution by flushing only toilet paper, pee and poop, and keeping the wrong things out of our sewer and storm systems.

Fats, Oils & Grease don't belong in our storm or sewer system. Learn some fun ways to avoid putting FOG in the wrong places.
