Crews for the Alameda Siphon #4 project continue to work round the clock to finish crucial work during the Coast Range Tunnel shutdown, even during these heavy rains.
The speed of work has slowed some so that workers remain safe. They're still on schedule, though.

Recent Earthquakes A Good Reminder to Store Water
The recent earthquakes are a good reminder for San Francisco Bay Area residents that it is not a matter of if but WHEN the next big earthquake will strike. We all must prepare.
One of the best and easiest things residents can do is store tap water for emergency use. After a big earthquake, water mains may break and homes may be without water for several days. We are upgrading our pipelines, reservoirs, pumping stations and other facilities to prepare for the next big earthquake.
Store at least one gallon of tap water per person per day to last at least three days. Store in a cool, dry place away from heat and sunlight and change water every six months (pour water on a plant and refill bottle). You can reuse 2 liter soda bottles or use other food grade plastic or metal bottles for storing water.

Coast Range Tunnel Shutdown Begins
The SFPUC has begun the long-planned temorary closure of the Coast Range Tunnel to perform maintenance and inspections on the tunnel and construct crucial pipeline connections to the tunnel in the Sunol Valley while it has been drained of water.
SFPUC customers will begin receiving water from reservoirs in the Bay Area exclusively until mid to late February.
Here is a view of the ventilation system constructed for this shutdown to keep air flowing through the tunnel.
