The water will drop in the landfill & the leachate will drop to the next lowest soil and refuse layer. In the finished landfill: If the field capacity of the soil covering waste is exceeded, the water percolates through the soil and into the buried solid waste. If the field capacity of waste is exceeded, leachate flows into the collection system / into the ground. Leachate escape
