I love the water how it fills to my skin. It’s so soft , my kids love it to. The service is great as well. I would recommend it to my friends and family.

Just had a water softener installed and a few days later, noticed a leak near the drain connection. Called my sales rep, Nick, on a Sunday and Chris was at my house within an hour and had it fixed within 30 minutes. No charge to me and no questions asked. Nick called shortly thereafter to check in and make sure everything was copacetic. I’m very impressed with the rapid response and professionalism of this crew!

The Best Water Softeners and Water Filters in Simi Valley.

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

In 2018, residents urged the City Council to disallow groundwater as drinking water, saying it was contaminated by the Santa Susana Field Laboratory.

The Simi Valley City/District distributes 14 million gallons of water each day to more than 26,000 homes and businesses within the community.

The primary supply for the City/District is the State Water Project, imported from Northern California. The State Water Project water is treated, filtered and disinfected at Metropolitan Water District’s (Metropolitan) Joseph Jensen Filtration Plant in Granada Hills. The treated water is conveyed by pipeline to Calleguas Municipal Water District (Calleguas).

Calleguas is the main supplier of water to the City/District and Golden State Water Company, Simi Valley’s water purveyors. In addition, Calleguas uses the Lake Bard Reservoir to store imported water from Metropolitan. The water treated at the Lake Bard Water Filtration Facility is reserved for emergencies, or planned facility outages. The other City/District source of drinking water is the Gillibrand Groundwater Basin located north of Simi Valley, accounting for 0.35% of the total water delivered within
the City/District service area. Groundwater from this basin is pumped to the Tapo Canyon Water Treatment Plant for treatment and disinfection, before delivery to the distribution system.

Is Simi Valley Tap Water Safe To Drink?

Environmental Working Group detected 14 contaminants in Long Beach tap water where levels reached above their recommended guidelines. This includes arsenic, chloroform, chromium-6, HAA5, nitrates, and TTHMs.
