About Living Water SoCal

Living Water SoCal has spent more than 20 years engineering water filtration and reverse-osmosis systems for one purpose: consistent, great-tasting coffee. We build and service everything from single-brewer inline filters to high-volume systems for multi-unit roasters, out of our facility in Simi Valley, CA.

We work exclusively with cafés, roasters, and restaurants — not general residential water treatment — because coffee water chemistry is a specialized problem. Mineral content, TDS, and scale all shift shot consistency, brew extraction, and equipment life in ways off-the-shelf filtration doesn’t address.

Our team installs and services systems across seven Southern California counties — Santa Barbara, Ventura, Los Angeles, San Bernardino, Orange, Riverside, and San Diego — and ships filter packs and assembled systems nationwide.
