Where Does San Diego Tap Water Come From?

San Diego is along the California coast and many of those cities have limited water resources. With this in mind, San Diego tap water is purchased from outside of the area and imported from secondary locations. In fact, 90% of San Diego tap water comes from outside of the area. The main portion of San Diego drinking water comes from the Colorado River Aqueduct, which was formed as a way to supply Los Angeles with water. These days, the Aqueduct joins with the State Water Project to supply water to many cities in California. The remaining portion of water that makes up San Diego tap water comes from raw water sources in the Sacramento-San Joaquin River Delta.

 

Can you Drink San Diego Tap Water?

San Diego drinking water is considered to be relatively safe. Over one million people are using, and drinking San Diego tap water every day. Not only does San Diego use this water, it’s also the water used in Imperial Beach, Del Mar, and Coronado! However, when you ask is San Diego tap water safe to drink, some might disagree. In the past, San Diego tap water was listed as one of the 10 worst in terms of drinking water based on chemicals found in the water. Many of the same contaminants that made the list are still found in San Diego drinking water. If you’re worried about San Diego water quality and are unsure if you should drink the water, a solution may be to get a water filter.

A water filter will remove toxins and other chemicals from your water and make it much safer to drink and use. Using a water filter can also improve the taste of your water.
