Orlando sits on the Floridan Aquifer, a massive limestone formation riddled with voids, caverns, and dissolution channels. When soil above these voids settles, sewer pipes settle with it. A lateral that was installed level in 1975 may now have a six-inch belly where waste pools and solids accumulate. The high water table across Orange County means your sewer line spends most of the year submerged in groundwater. Clay pipes absorb moisture, soften, and crack. Orangeburg fiber pipe disintegrates. Even modern PVC can shift when soil loses support underneath. Trenchless sewer line repair using CIPP often stabilizes these lines without excavation, but only if the pipe structure has not completely failed.
