Abstract
A waste water evaporation system includes an elongated evaporation bed having an upper layer of rock pieces and a lower sand layer. A perforated pipe extends in the rock layer to slowly deliver waste water for percolation into the sand layer; and a lower layer of rock pieces under the sand layer may receive drainage of excess water for recirculation to the top layer via a sump and pump.
