Governor Signs Assembly Bill 818!

Did you know you shouldn’t flush wipes even if they are labeled “flushable?” Wastewater agencies across the country have been working to spread the word that only human waste and toilet paper should be flushed for years. After years of legislative work, AB 818 has been signed into law by the Governor! In compliance with AB 818, all wet wipes packages are required to include a “Do Not Flush” symbol and warning on each individual package. Flushing wipes can have a negative impact on your household’s sewer systems, infrastructure and our environment. Look for the warning on shelves near you starting July 2022!
