Conserve Water - Hetch Hetchy Tunnel Shutdown

Two workers with headlamps walking through a tunnel at a construction site, with lights and machinery visible.

Starting December 3, 2024, through March 15, 2025, maintenance will be performed on the Hetch Hetchy Mountain Tunnel. During this time, our Alternative Water Treatment Plant will be in operation, which means a reduced pumping capacity.

We’re kindly asking for your help to conserve water by:

  • Cutting back on non-essential water use (like washing cars or cleaning patios)
  • Taking shorter showers
  • Turning off the tap while brushing your teeth or washing dishes
  • Running dishwashers and laundry machines only when full
  • Check for and repair leaky faucets

Every drop counts!
