What you flush down your drains and toilets makes a huge different for our wastewater system. You can help keep things flowing smoothly for everyone by only flushing the Three Ps – pee, poo and toiler paper. These three things can breakdown properly during the treatment process. Anything else may result in a sewer overflow in your home, or a blockage known as a “fatberg” in our sewer lines. Check out our What not to Flush for more information.
