Study on Recycling Scheme of Lake Mead Wastewater

Abstract

There is a sever draught happening in the Mead Lake that the observation of the lake elevation is decreasing dramatically. With increasing water demand in people’s life, people need to find more supply for them to meet their needs. There is a good way that recycling the wastewater from sinks, toilets and showers. For some people, they may think it impossible and even disgusting but this kind of technology exists and developing. Before conducting the wastewater recycling program, we need to investigate more about the impact of drought on reservoirs like the volume and elevation change of the Lake Mead and consider wastewater recycling as a solution to water shortages, Introduced by the environmental issue, the wastewater recycling program can be conducted. We consider some factors that may influence the plan like the changes in the water level of Lake Mead, demand of water and cost. We also prioritize the decisions that local leaders need to make and their impact. Finally we give our plan for this wastewater recycling program into three stages.
