has two historic train depots, the inactive Nevada-California-Oregon Railroad Depot and the active Amtrak depot at Reno station, originally built by the Southern Pacific Railroad. Amtrak provides daily passenger service to Reno via the California Zephyr at Reno station and via multiple Amtrak Thruway Motorcoaches that connect to trains departing from Sacramento. Air The city is served by Reno–Tahoe International Airport, with general aviation traffic handled by Reno Stead Airport. Reno–Tahoe International Airport is the second busiest commercial airport in the state of Nevada after Harry Reid International Airport in Las Vegas. Reno was the hub and headquarters of the defunct airline Reno Air. Utilities The Truckee Meadows Water Authority provides potable water for the city. The Truckee River is the primary water source, with purification occurring at two plants, Chalk Bluff and Glendale. The Chalk Bluff plant's main intakes are west of Reno and south of Verdi, with the water flowing through a series of flumes and ditches to the plant. Alternative intakes are below the plant along the banks of the Truckee River itself. The Glendale plant is alongside the river, and is fed by a rock and concrete rubble diversion dam a short distance upstream. Sewage treatment for most of the Truckee Meadows region takes place at the Truckee Meadows Water Reclamation Facility at the eastern edge of the valley. Treated effluent returns to the Truckee River by way of Steamboat Creek. NV Energy, formerly Sierra Pacific, provides electric power and natural gas. Power comes from multiple sources, including Tracy-Clark Station to the east, and the Steamboat Springs binary cycle power plants at the southern end of town.
