Yes, over time a biofilm (or slime) may grow in a water supply system treated with UV light. This may require occasional treatment with chlorine to remove any biofilm within the pipes. To remove biofilms flush all pipes with a 1mg/L solution of chlorinated water making sure to open all taps to allow all chlorinated water to drain.

Can UV light be used in wastewater treatment facilities in Florida?
Most domestic wastewater treatment facilities in Florida must meet either "basic disinfection" (applies to most surface water discharges) or "high-level disinfection" (applies to many reuse systems). These two levels of disinfection are described in Rule 62-600.440, F.A.C. UV can be reliably used to meet basic disinfection criteria.
Can UV light be used for basic disinfection of effluent?
These two levels of disinfection are described in Rule 62-600.440, F.A.C. UV can be reliably used to meet basic disinfection criteria. Basic disinfection essentially requires that the effluent after disinfection contain less than 200 fecal coliforms per 100 mL [see Rule 62-600.440 (4), F.A.C. for detailed requirements].
Is UV disinfection a wastewater treatment system?

How often should you change the UV bulb for water treatment?
once every 12 monthsHow often do I need to change my UV lamp? UV lamps should be replaced once every 12 months. UV lamps have a lifespan of approximately 9,000 hours. Calculated out, this means the lamp can operate for about 375 days before requiring a replacement.
How do you clean UV water?
There's a lot of complex science behind the process of UV water purification, but the idea is quite simple. Water runs through the steel chamber where it is exposed to the UV light, which deactivates bacteria and waterborne pathogens. Then the water is safe to consume.
Do UV lights lose their effectiveness?
Like your average light bulb, UV lights have a finite life span that requires them to be changed on a regular basis. As these lights operate, they slowly lose their effectiveness as a germicidal agent by about 15 percent each year.
How do I know if my UV light is still good?
A UV lamp should not be kept running after 3 years. The UV system should just be turned off until the lamp is replaced, because it effectiveness is spent and it will simply waste energy. The excessive energy consumed by an aging lamp can cause the power supply to overheat, potentially causing a complete system failure.
How often should I clean UV sterilizer?
Thorough cleaning and maintenance of the quartz sleeve is recommended every 12 months. You may want to clean the UV sleeve at the same time you're replacing the UV lamp each year.
What is the life span of a UV light?
12 monthsTypically, an Ultraviolet or UV lamp last 12 months or about 9000 hours. The lamp will stay lit longer than that time but after that year of use it's ability to kill bacteria will slowly diminish to zero giving you a very false sense of security.

This method of disinfection has the following benefits: You don't have to handle potentially dangerous chemicals.
How long does UV take to sterilize water?
approximately 20 to 30 secondsUV disinfection has a shorter contact time when compared with other disinfectants (approximately 20 to 30 seconds with low-pressure lamps). UV disinfection equipment requires less space than other methods. Low dosage may not effectively inactivate some viruses, spores, and cysts. known as "dark repair.
Is it safe to drink water exposed to UV light?
Yes. UV light is normally effective against all viruses, bacteria and protozoa. However, some microorganisms such as Cryptosporidium and Giardia have protective or thick cell walls that some low power UV light systems are not able to penetrate.
