The City of San Diego takes pride in providing safe and clean water to its residents and not only for a few years but for a hundred years. It also caters to other cities like Coronado, Del Mar, Imperial Beach. The city has never sold a drop of water that is deemed hazardous by a federal agency, local, or state. While being reliable and outstanding for a long time, San Diego aims to keep this record for more years to come. What’s more surprising about this is that the sources where most San Diego water comes from, travel a thousand of miles prior to reaching the city. That being said, is it really safe to drink its tap water?

To Drink Or Not To Drink?

San Diego is proud of delivering clean and safe water and a lot of people can attest to it; however, there are still a number of complaints when it comes to the taste of the water. Some may still find it awful and basically, it’s because of the chlorine added to it for transportation. Therefore, to ensure the best quality of water in homes and businesses, it’s best to install a whole house water filter system.

This system is capable of filtering all the water that penetrates your home by connecting the main water line to all the water dispensers such as the laundry, faucet, toilet, shower, and water heater. Its role is to remove bacteria, virus, chemicals, organic substances, and other contaminants that may cause minor or severe sickness. It also helps in keeping the clothes clean and soft by removing scales and other unnecessary substance. In addition, it prolongs the life of plumbing and appliances by filtering sediments that may cause trouble in the long run.

Where Does San Diego Get Its Tap Water?

Despite serving safe and clean water, San Diego’s water supply is limited. In fact, the city has to purchase 90% of it from other places. It is mainly attached to the Colorado River Aqueduct, which was basically created for Los Angeles. The Aqueduct is linked to the State Water Project going to San Francisco, and it acquires unfiltered water supply from the Sacramento-San Joaquin River Delta. Considering this, the water coming out of the tap has traveled thousands of miles which are then stored in reservoirs. To ensure that the water is safe and clean, the City’s Public Utilities Department conducts several treatment processes from its three water treatment plants.

Coagulation, flocculation, and sedimentation – these are just some of the initial steps conducted to raw water to filter heavy particles. To remove smaller debris and produce a crystal clear outcome, the water will undergo the filtration process. Meanwhile, to filter bacteria, viruses, and other pathogenic organisms, the water is treated and every water plants have various approaches when it comes to disinfection. For instance, the Otay Water Treatment Plant utilizes chlorine dioxide while the Alvarado and Miramar Water Treatment Plants use ozone – which is just primary disinfection. To remove microbial contamination, the treated water will undergo a second disinfection. Through this, chloramines are formed with the help of chlorine and ammonia. Finally, the pH is adjusted to control corrosion.

When it comes to regulations, tap water in San Diego is regulated by the EPA (Environmental Protection Agency) which implements strict guidelines – health guidelines to be exact. Nonetheless, there are contaminants found in the water which are “below the legal limit” set by the agency. It may not pose an immediate threat but may be a problem in the long run. Therefore, it’s still ideal to have a water filter system installed in every home and office to ensure safe water to drink.
