Some people live in areas where coliform is a recurring headache—like a neighbor’s dog that keeps digging in your yard. For these folks, a disinfectant system is the way to go. Ultraviolet (UV) light systems are incredibly popular.
UV light zaps bacteria as water passes through a tube. It’s non-chemical, doesn’t change the taste, and uses about as much electricity as a lightbulb. Imagine a tanning bed for your water—but only for the germs, not you.
You can also use a reverse osmosis (RO) system under your sink, but that’s slower and more expensive. For a whole-house solution, UV plus a sediment filter is the gold standard. It’s like installing a bouncer at the door of your home’s water supply.

Don't Forget the Cistern or Storage Tank
If you collect rainwater or use a storage tank, coliform love sitting in warm, sunlit water. That tank is basically a five-star hotel for bacteria if you don’t clean it. At least once a year, scrub the walls with a mild bleach solution and rinse thoroughly.
Cover the tank tightly. Sunlight feeds algae, and algae feed bacteria. A dark, well-ventilated, and screened tank keeps coliform from booking a room. And please, check for dead leaves or insects floating on top—they’re not just gross; they’re bacterial couriers.
Remember, clean water isn’t about being a germophobe. It’s about being kind to your future self. The self that doesn’t have to cancel plans because of a tummy ache. The self that makes iced tea without second-guessing the ice.
