| valign="top" | - effective for inactivating waterborne pathogens <br>

- simple to apply at the household and community levels<br>

- relatively low cost, depending on scale of use and UV lamp system used<br>

- does not use chemicals or create tastes, odors or toxic chemical by-products

| valign="top" | - the need for a source of lamps, which have to be replaced periodically (typically every year or two <br>

- UV provides no residual chemical disinfectant in the water to protect against post-treatment contamination, and therefore care must be taken to protect UV-disinfected water from post-treatment contamination, including bacterial regrowth or reactivation
