Given the growing threat of extreme hot, windy weather, Pacific Gas and Electric Company (PG&E) is alerting customers to be prepared for power outages to minimize the risk of power lines sparking a fire. If extreme fire danger conditions threaten a portion of the electric system serving our region, it will be necessary for PG&E to turn off electricity in the interest of public safety. This is called a Public Safety Power Shutoff (PSPS). Learn more about Public Safety Power Shutoffs that could impact you this wildfire season. Visit

Tuolumne Utilities District is actively planning for the potential of extended power outages with the goal of minimizing water service interruption. The challenge is the array of infrastructure and terrain that the District’s service area covers. The District is aggressively pursuing backup power generators to meet the power needs of critical infrastructure. If a PSPS event occurs for an extended amount of time, TUD will be asking all customers to conserve water and limit outdoor water usage until power is restored.

The District encourages all Tuolumne County residents to be prepared for a PSPS event. Steps you can take today:

  • Prepare your emergency kit! Include water for your family, store at least one gallon of water per person per day for three days, for drinking and sanitation.
  • Go to and sign up for PG&E alerts to be notified of a PSPS event.
  • In the event of a PSPS event, stay connected with TUD on Facebook and at

Water Pipe Emergency

If a water pipe bursts at your home, we recommend that you immediately turn off your main water valve. This valve is typically located on a water pipe that comes out of the ground and into the side of your house, frequently located below a hose bib. If you are unable to locate this valve or turn it off, contact TUD and we will assist you.

If you see conditions such as an open or damaged fire hydrant, water seeping up from underground or other signs that an underground water line may be broken, please report it to TUD immediately.

Sewer Emergency

Most TUD sewer customers don’t like to think about a possible sewage spill. But, they do happen. Sewage spills occur when the wastewater being transported via underground pipes overflows through a manhole, cleanout or broken pipe.

Common Causes of Sewer Spills

Grease: Grease builds up inside and eventually blocks sewer pipes. Grease gets into the sewer from household drains, as well as from poorly maintained commercial grease traps and interceptors. Grease is the most common cause of pipe blockages. How to prevent grease building up? Do not put grease down drains. Wipe down or scrape plates, pans, etc. into grease can. Once the grease and or can is cool, dispose of it in your garbage.

Structure problems: There can be many reasons for a sewer backup, many of them are caused by structure problems caused by tree roots in the lines, broken/cracked pipes, missing or broken cleanout caps, or undersized sewers can cause blockages.

What if you encounter a sewer spill?

If you see a sewage spill occurring, please call TUD immediately at 209-532-5536 and notify them of the problem. The TUD Wastewater staff will be notified seven days a week, 24 hours a day if an emergency occurs. We will respond as quickly as possible to get your issue resolved.
