UV Water Purification in El Segundo, CA

UV purification uses a 254-nanometer UV-C lamp housed in a stainless steel reactor chamber to inactivate bacteria, viruses, and protozoan cysts as water passes by. The treatment is instantaneous, chemical-free, taste-neutral, and adds nothing to the water. UV is the final stage in a complete filtration train — it requires clear, low-turbidity input water, so sediment, carbon, and softening always come first. Most common in well-water properties, commercial applications, and homes with immunocompromised members.

Most El Segundo households on LADWP municipal supply don't need UV purification — the chlorine residual in the distribution system handles standard microbial concerns and EPA standards are met at the meter. The El Segundo properties that do warrant UV fall into three categories: hillside or unincorporated parcels drawing from private wells, commercial properties (restaurants, medical offices, daycares) where additional microbial barriers are part of compliance or risk reduction, and residential homes with immunocompromised members where the redundancy is worth the maintenance overhead. We assess at no cost during a 35-minute site visit and recommend against UV when it isn't warranted. When it is the right call, we install commercial-grade stainless steel reactors with intensity monitoring and an audible low-output alarm so you know immediately if the lamp degrades.
