The system starts in Hetch Hetchy Valley, inside Yosemite National Park. The system also generates up to 400MW of electrical power, depending on rainfall, most of which is sent to San Francisco via city-owned power lines. [63] After water leaves Hetch Hetchy, it passes through tunnels towards powerhouses. Three pipes then bring the water across ...
