Cars, trucks, RVs, tractors, delivery vehicles, and even riding mowers can create soil compaction above the drainfield, reducing its ability to absorb wastewater. Heavier vehicles can crack distribution boxes, snap PVC lines, or collapse older concrete or steel tanks. This guide teaches homeowners how to identify where their tank and lines are located, how far vehicles must stay away, and what to do if accidental damage has already occurred. The Septic Saver course explains how to restore soil absorption, prevent future compaction, and recognize early signs of drainfield stress. You’ll also learn why snowplows, dumpsters, construction equipment, and visitor parking can silently destroy a septic system. With the right awareness, homeowners can prevent structural damage and protect their investment for decades.
