Why Do Oceanside
Homeowners LOVE Us?

We have used Culligan San Diego for over 10 years. We rented a softener for 4 years and then purchased a system when we bought our home. We have always had great service! They are friendly and helpful on the phone and quickly send a repair guy when needed (and we’ve only needed a repairman 1 time in 6.5 years of owning our system).

Product quality is great. Taste is wonderful. No more buying water at the store. No more refilling jugs. No more running tap water through filter devices. I am particularly impressed by the technicians who make the installation quick, safe, and invisible. And when I moved, they were there to move my equipment at no charge.

A great company. The communication is on point and prompt. Everything has been so smooth. They send reminders (really helps me) and they do what they say. My favorite water delivery company.

The Best Water Softeners and Water Filters in Oceanside.

With this combination of water resources, Oceanside water quality often faces our share of water filtration and treatment issues:

The City of Oceanside has three sources of drinking water. One source of water supply is imported water that is purchased untreated from the San Diego County Water Authority (SDCWA). This raw water is then treated at Oceanside’s Robert A. Weese (R.A. Weese) Water Treatment Plant, and accounts for about 82% of Oceanside’s water. The second source is treated drinking water purchased directly from SDCWA which is blended with water from the Carlsbad Desalination Plant; this is about 8% of Oceanside’s water supply. The remaining 10% of the City’s water supply comes from Oceanside’s Mission Basin Groundwater Purification Facility (MBGPF).

Residents of Oceanside may notice problems with hard water, as their average hardness is 141 PPM and 8.2 grains per gallon.

Whether you’re dealing with a stale, chlorinated taste or odor, or looking for ways to increase the efficiency of your home, Culligan of San Diego has a water filtering solution designed for the type of water problems Oceanside deals with most.
