Your water company

Ken Harrington, YSPUC manager, checks equipment at one of the many wells the company operates.

What you should know

We have several main wells that provide clean, healthy water for each of the lots and homes. We manage and operate Yosemite Spring Park Utility Company (YSPUC) with a separate board of directors and have employees that work for YSPUC to maintain the system.




Business office hours: 8 a.m. to 5 p.m. Monday through Friday. The business office phone number is (559) 517-3799. The business office is closed on all major holidays.


When you are notified that it is OK to flush, start by turning on a hose outside of your home closest to the point where water enters your house. Run the water for approximately 15 minutes or until it becomes clear. If the water does not clear up within 15 minutes, STOP running the water and contact us immediately.

It is also very important not to flush UNTIL YSPUC notifies you to start the flushing process.

We apologize for any inconvenience this may cause and we will issue you 1 flushing credit that will be applied to your next month’s bill.


Water utilities, like any other business, must be able to cover their daily operational costs, as well as provide some profit to fund additional growth, replace and repair aged or damaged equipment, and meet financial requirements.

The California Public Utilities Commission determined that, based on its number of customers, the YSPUC can recover 65 percent of its fixed costs through a Readiness to Serve charge.

Without this charge, the rates that YSPUC would have to charge for water would be much higher, as sales of water alone would not cover the costs of operations, at a rate that would appear to be reasonable to the consumer.


Should you need emergency assistance after business hours, on weekends, or on a holiday, please contact us by using our emergency line: 760-4349.

Please contact us for any water company-related emergency during the times specified above. We would rather find out about the problem at 2 a.m. when the problem is small rather than at 7 a.m. when the problem has become very large.


Meters are read monthly and billing statements are sent out by the 5th of each month. Please call us if you do not receive your statement by the 15th of each month.



Your water is being supplied to you from deep rock wells, and so occasional discolored water can occur. Slight discolor that quickly comes and goes is not a concern.

However, if your water becomes dark and stays that way, then IMMEDIATELY take the following steps:

1. Contact the office at 658-7451 from 8 a.m. to 5 p.m. Monday through Friday.

2. After hours, call 760-4349

3. DO NOT turn on any water in or around your home, unless instructed by YSPUC.

Never run your hot water while it is discolored. However, if you were running the hot water when your water became discolored, you may need to drain your hot water heater as well.

Ken Sartain
YLOA Director

As your newly elected board member and vice president of the YSPUC, I have been learning all I can about how our water system functions and the challenges our capable staff face on a daily basis.

Many of us have experienced this scenario: Turn on the tap….no water. What happened? With increasing frequency our aging water system will fail, causing water outages. These outages are not only inconvenient for YLP homeowners but also costly to repair. And many times they will happen at the most inconvenient time.

On Friday, Dec. 28, at about 3 p.m., I gained first hand insight into a mainline pipe failure response. The location was East Lilley Mountain Way. When I got there, the crew was already onsite, headed by our water department manager, Ken Harrington. The area of the failure had been valved off and the backhoe tractor had begun its work digging out the failed 24-foot section of pipe.

Since this is a high-pressure area, parts of the roadway had been severely undermined and caved-in from being washed out by water gushing from the underground pipe breach.

Over the course of several hours, I stayed there to watch the repair process in action. I want to share that experience with you through a series of photos I took. I’ve captioned each one to explain what’s going on and who’s doing the work.

Keep in mind that the working conditions for this break were on the favorable side. It wasn’t raining, snowing, pouring down rain, freezing cold or blazing hot, or in the middle of the night on a weekend or holiday.

Any of these scenarios could have happened and they HAVE happened but it has never kept our faithful crews from showing up and getting the job done!

Ken Sartain is also a member of the YLOA Engineering Committee and chair of the Communications Committee.
