UV Water Purification
UV Water Purification in Daly City
UV disinfection for the north Peninsula homes and businesses that need it.
When UV makes sense
UV water purification in Daly City is not something most homes need. The regional water arrives disinfected and stays that way through the city's pipes. Where UV earns its place is with storage tanks, private wells or springs on larger properties up the coast, and households where a doctor has advised extra protection.
A UV chamber inactivates bacteria, viruses and protozoa with ultraviolet light, adding nothing to the water. For it to work, the light has to reach every microbe, so sediment, rust and iron must be removed first.
If you are on regional water without a storage tank, we will tell you plainly that UV is unnecessary.
In older buildings
Some older buildings in the area have rooftop or basement storage tanks that were never designed with modern disinfection in mind. In those cases, UV after a sediment and carbon stage is a sensible safeguard.
Rust from galvanized pipes can coat the quartz sleeve, so in older buildings we always put good sediment filtration ahead of the lamp.
We also check how the water is stored and moved before the lamp. A tank with a loose lid, a long dead-end line or a pressure pump that cycles too often can all undermine disinfection, and no lamp makes up for that. When we find something like that, we explain it in plain terms and price the fix separately, so you can decide what to tackle first.

Questions people ask
Do I need UV on city water?
Usually not.
Does it change the taste?
No. Nothing is added.
How often is the lamp replaced?
About once a year.
How often does the lamp change?
Once a year for most units, whether it looks lit or not, because the useful ultraviolet output fades before the glow does. We send a reminder.
Does UV change the taste?
No. It adds nothing and removes nothing you can taste, which is why carbon is often fitted ahead of it.
