We All Think Blue

For more than 20 years Think Blue San Diego has implemented innovative, proactive steps to stop pollution before it gets into storm drains. But to keep it that way, we must all dive in and do our part. Reducing stormwater pollution in our neighborhoods and communities is easy when We All Think Blue.

This is the rainy season, San Diego! 🌧 Rain is rare in the @cityofsandiego. But when it rains, stormwater flows from roofs, streets and sidewalks into gutters and inlets and enters an extensive underground network of pipes. This robust system of infrastructure protects San Diegans and our water supply every day. πŸ’¦πŸ’§ However, we all need to do our part to keep each other safe and prevent flooding. How? By preventing pollution and picking up trash that could potentially clog our storm drainpipes, you can be part of the solution. πŸ—‘ Pick up trash and deposit any debris in the trash πŸ‚ Sweep or pick up leaves and dispose of them in the green bin 🧹 Do not sweep or dump anything down a storm drain Thank you and Think Blue San Diego πŸ™ŒπŸŒŠ . . . #ThinkBlueSanDiego #SanDiego #SDRain #SanDiegoRain #PollutionPrevention #StopPollution #PickUpTrash #WaterPollution #StormwaterPollution #Flooding #SanDiegoFlooding

Join us and @iloveacleansd for the biannual Storm Drain Stenciling Day on Saturday, Dec. 10! πŸŽ¨πŸ–Œ Come with us as we walk around the neighborhood and stencil storm drains with a conservation message. Storm drains are the big gaps in the curb you see around our homes and businesses. These gaps are meant to move water out of our neighborhoods and out to our ocean quickly so that when it rains, our streets don’t get flooded. This is an important safety feature that keeps us from walking in foot-deep water during the winter. πŸ’¦πŸ’§ What a lot of people don’t know is that water entering storm drains is NOT treated. So, any trash or debris that water carries eventually goes into our lakes, rivers and the ocean. By stenciling storm drains, you can help spread the word about how important the stormwater system is to our neighborhood quality of life and our environmental health! 🌊 πŸ“… Saturday, Dec. 10, 2022 πŸ•˜ 9-11 a.m. πŸ“ Tuxedo Park, 6900 Tuxedo Road, San Diego, CA 92119 πŸ”— Register at cleansd.org . . . #ThinkBlueSanDiego #ILACSD #StormDrainStencilingDay #StormwaterPollution #Stormwater #PollutionPrevention #SanDiego #TuxedoPark

This year, we are grateful for the many San Diegans who have pulled up their sleeves to help clean up trails and beaches, made the time to learn more about the importance of clean stormwater and taken simple steps to prevent pollution year-round. 🧑 But this work never ends. Did you know that Americans throw away 25% more trash during the winter holiday season between Thanksgiving and New Year’s? That is about 25 million tons of more garbage! πŸ—‘ While we are all excited about the holiday season, we must remember that this trash can end up in our waterways and beaches. πŸ’§πŸŒŠ Unlike wastewater, stormwater is NOT TREATED and can harm our environment and public and marine health. πŸ πŸ¬πŸ¦žπŸ¦† So, join us in celebrating responsibility and making an effort to rethink our holiday waste. Here is how πŸ‘‡ πŸ‚ Don’t pour fat and grease down the drain. Pour it into a sealable container and dispose of it in the trash. πŸ‚ Use your reusable dishware and food containers to prevent pollution from single-use plastics. πŸ—‘ Secure your trash and recycling bins to ensure waste doesn’t enter our storm drains.

This is your LAST CHANCE to vote on your favorite name for our new electric mini street sweeper! πŸ§ΉπŸ’¦πŸ’§ πŸ‘‰ Go to ThinkBlue.org between now and Nov. 23 to vote for your favorite name out of the three finalists and automatically enter our GIVEAWAY to win two tickets to @SeaWorldSanDiego. The winning name will be announced in late November. Our first 100% electric mini street sweeper is good for our streets, water and air! By removing sediment, metal particles and other hazardous waste products from our streets and bikeways, this sweeper helps beautify our neighborhoods and prevent pollution from entering storm drains.
