Many of those looking for toilet paper may think that items such as napkins, paper towels, tissues, or even flushable wipes are ok to flush down the toilet -- they are not. These items are the leading cause of sewer backups because, while they may go down the toilet, they do not dissolve like toilet paper does. Undissolved materials often create blockages in sewer lines, resulting in costly sewer backups for both the resident and the City. Please do not flush toilet paper "alternatives" down the toilet.
