objectionable taste of chlorine or other treatment chemicals found in many treated ?waters. In addition to the treated water, approximately 15,000 acre-feet per year of untreated water could be made available for irrigation purposes. It is considered that such an amount of water would be sufficient to provide irrigation for all of the Class 2 land in the vicinity of Pittman. METHOP OF SUPPLY There is indicated on the attached drawing one possible method of supplying water from Lake Mead, through the water supply and treatment facilities at the Basic Magnesium Plant to the popula­tion of the Las Vegas Valley. It is not intended to represent that this method is the only, or even the best, method of effecting this supply. It is, however, a possible method and, as such, has been used for the purpose of determining the economic feasibility of using the Basic Magnesium Plant's facilities to provide the water deficit. It consists essentially of bringing the water from the reservoirs at the Magnesium Plant through a 30~in- piPe to a pumping plant located southeast of the City. Water would be pumped from this plant in two lines. The first would supply the Army Air Field and North Las Vegas. The second would provide a supply into the reservoirs of the present city distribution system, owned by the Las Vegas Land and Water Co., and would supply the entire populated area south of the city limits. This method also contemplates the provision of distribution systems for Pittman, Whitney, North Las Vegas, and the populated area south of Las Vegas for the purpose of this economic analysis. B
