Always call the Public Works Department first if you notice sewage or water coming up in your floor drain or basement toilets. We have people on call 24 hours a day to respond to these types of emergencies. A quick call can verify whether the plug is in your own sewer lateral or perhaps a city main line. One easy way to tell is if the water backing up in the floor drain is constant, and you are not using any water, it may be a city main. If the water only backs up when you use a washer, dishwasher, or even run water down a sink, it is most likely your own line. Tree roots are usually the main cause of sewer line backups, both private and public. If you have had trouble in the past it is a good idea to routinely have your sewer lateral cleaned by a licensed plumber or sewer maintenance company. South Ogden 's phone number is 479-7130 Monday-Friday 7:00-3:30, or after hours emergencies 629-8221. Please keep these phone numbers available if such an emergency arises.
