In Las Vegas Valley, water and wastewater are intrinsically related because treated wastewater effluent is returned back to Lake Mead, the drinking water source for the Valley’s residents. An alternative source of water to Las Vegas Valley could be realized by using membrane technology, specifically reverse osmosis. To evaluate the effects of reverse osmosis in the management of water quality in the Las Vegas Valley, a complete water balance was developed. The data gathered was input to a spreadsheet and iterations were performed until a balance was achieved for the entire system. At year 2050 and 400 MGD, the TDS concentration difference between discharging tertiary effluent to Lake Mead or implementing reverse osmosis treatment, in downstream Colorado River, is estimated at 30 to 50 mg/L.
