Indianapolis sits on glacial till with dense clay subsoil that expands when wet and contracts when dry. This constant movement puts pressure on rigid sewer laterals, especially older terra cotta and cast iron pipes installed before 1960. Freeze-thaw cycles make it worse. Water infiltrates cracks in late fall, freezes and expands through winter, then thaws in spring, widening those cracks. By summer, tree roots from Indianapolis's urban canopy push through the gaps, creating blockages that turn into backups during heavy rain events. Many older neighborhoods still have combined sewer systems that overflow during storms, sending raw sewage back through floor drains.
