What Causes Gas Smell from the Sewer When It Rains?
Many times in rural areas that begin to see development, a leach field may have existed previously. If the development doesn't properly remove the tile forming the bed of the leach field, the wastewater will drain to a low point, frequently the basement of a nearby house. As a result, the basement will smell as the water leaks into the basement drain point in the floor. Anyone planning a basement should make sure there are no past leach fields within 30 feet of the dig area.
