Each home's toilets and drains lead out of the house in a sewer service or "lateral" line, which connects to a sewer main line. Everything from the house to the sewer main line is the homeowner's responsibility. Any back-ups or overflows coming from the sewer main line should be reported to the Waste Water Collections Department by calling Utilities Dispatch at 940-349-7000.
If you are experiencing a sewage backup or offensive odor in your home, call a plumber immediately. If your plumber finds that the blockage is beyond the sewer service/lateral line, call Utilities Dispatch at 940-349-7000.
