Call the Wastewater Collection Department first at (806) 296-1169 on weekdays or (806) 296-1182 on nights and weekends. Even if you suspect the problem may be on your service line, it’s best to call the city first before you call a plumber.
A crew will check the city’s main lines to either identify and repair the problem or to determine whether or not you need to call a plumber. The city will clean the public sewer main line regardless of where the problem exists. This step could save you an unnecessary plumber’s bill.
