What is the difference between a seepage pit and a cesspool?
Both of these systems rely on a pit as the water absorption system. In general these will be older systems because in most areas permits cannot be obtained to install pits anymore. A seepage pit has a septic tank in front of it which collects the solids and greases. A cesspool acts as both the septic tank and the soil absorption system. While many cesspools and seepage pits operate for years, they are more prone to failure and are more difficult to restore. Proper maintenance can help extend their lives.
