Blockages accounts for almost half, at 43%, of all sanitary sewer overflows. You should avoid sending any foreign material down your sewer pipes. Paper products, wood, metal, and even toys are flushed down the toilet all too often. Worse than any of these is F.O.G., which solidifies in the lines of the collection system and forms large chunks that get stuck or builds on the walls of the pipes, narrowing the lines headed to the treatment plant. A blockage of the collection system could cause the sewer to overflow, also known as sanitary sewer overflow (SSO), and spill into ditches and thusly to our ship channel and bay. It could also cause the sewer system to backup into your yard or even your home. Untreated wastewater can be a costly cleanup and can cause serious health issues for you and the surrounding community. Another outcome is a fish kill in our waterways. Nobody wants to see wastewater bubbling out from manhole covers and traveling down our storm sewer, and you certainly don't want it backing up in your yard or home.
