Top loading (with vent) ensures maximum surge capacity for the drywell. Please note that venting your leaching pit (or any septic field) is most strongly suggested... insufficient venting at both ends of lateral lines is the best cause of leach field failure (after lack of proper two area filtered septic fish tank). Oxygen continues the drainage pit dry and the soil around it healthier.
