A lateral sewer pipe connects your home/building to the sewer owned and maintained by GPSD. It serves to move wastewater into the sewer main. Problems related to lateral pipes are the homeowner’s responsibility. Homeowners experiencing slow drainage or complete blockage may have tree roots, grease, baby wipes, etc.; lodged in the lateral sewer pipe. GPSD employees can determine if problems are located in the lateral sewer or GPSD sewer and recommend what you should do.
If neighbors are having similar slow drainage, there is a chance that there is a problem in the public main. If the problem appears to be limited to your home, there may be a problem with the lateral sewer pipe. Remember to call GPSD first, before calling a plumber.
