Under normal circumstances, the usual method of disposal of wastewater in a desert environment has been to either discharge into an existing stream bed or provide percolation ponds for treated effluent. However, potential contamination problems and requirements by the Environmental Protection Agency necessitated a unique approach to wastewater disposal for the City of Las Vegas, Nevada. The proposed plan was to export treated wastewater to a playa lake where a system of evaporative ponds around the perimeter of the playa would contain the wastewater for evaporation, utilizing the palya bottom for more saline and flood relief waters. Reconnaissance studies were conducted to evaluate three potential site areas. Following selection of the preferred site, extensive geologic and soils studies were undertaken to determine the areal extent and impermeability of the playa lake. /Author/
