Interior drainage systems are longer-lasting and more durable than exterior drainage systems. This is because exterior drainage systems can clog up with dirt and become useless over time. When the system gets clogged, it is difficult to access since they are buried underground or beneath landscaping, and therefore becomes nearly impossible to flush out the system. Other risks such as buried gas/water lines, sewage, or electrical wiring can also make repairs extremely hard to take care of, especially if it involves excavation.
