Where does my water come from?
Your water flows straight from the pristine American River watershed to Folsom Lake.

How is my water treated?
Your water is treated at our treatment plant. We conduct several steps to filter and disinfect water of any impurities and/or contaminants. Once completed, it is stored in a 62-million gallon reservoir for distribution to Wholesale and Retail customers.

How do I know my water is safe to drink?
San Juan water meets or exceeds all federal and state drinking water standards. We continuously monitor and test your water to ensure quality. Check out our Consumer Confidence Report to see for yourself.

How “hard” is my water?
Our water is considered ultra soft. Due to San Juan's very low level of calcium, magnesium and manganese, you have no need for water softeners. 

If you have recently purchased a new appliance, check the manual for information about appropriate detergent levels relative to San Juan's hardness level, which is 1.37 grains per gallon (23.6 parts per million).

Should I buy bottled water?
While you may choose to drink bottled water for personal reasons, you do not need to buy it for health reasons. Water quality standards for San Juan Water District and other California water providers are more stringent than bottled water standards. According to a study published by the Natural Resources Defense Council, bottled water is not necessarily cleaner or safer than tap water.

Why is my water sometimes different in the summer than in the winter?
During the summer, your water pressure and taste may be slightly different than it is during the winter. Here is why: 

• Pressure – During the morning hours, water use can be eight times higher in the summer. 
• Taste – As Folsom Lakes water level drops and temperatures rise, your water may sometimes taste different. At all times, the water from San Juan Water District is safe to drink. 
• Temperature – As Folsom Lake's water level drops and temperatures rise, your water may be warmer than usual. Keep a pitcher of tap water in the refrigerator for a cool, refreshing drink.

Is there fluoride in my water?
No. Your water does not contain fluoride.
