As I talk with folks in Tennessee about rainwater harvesting, I’m noticing that everyone handles rainwater a little differently. Some people don’t treat the rainwater at all, while others bring it to a standard equivalent to potable water. So I’m here to explain how our rainwater systems work, and why we do things the way we do.

As rain falls on a building’s roof, the rain is usually soft, clear and free of microorganisms. During collection and storage, however, there is a potential for microbiological contamination. This contamination can come from a number of sources, including fecal matter from birds, squirrels, mice and other critters. Even leaf litter, if kept damp for long enough, can turn the water in your tank a little funky.

So how should you handle rainwater capture?

If you are a homeowner, you want a system that you can trust, one that will provide you with many years of trouble-free use. If you are a homebuilder, an architect or an engineer, you want to recommend a system that inspires confidence both in you and your client.

On top of filtering the rainwater twice (one primary filter for large debris like leaves and twigs, and a secondary filter for everything else), our system effectively treats the rainwater with small amounts of chlorine so that the water is always fresh, clean and ready to go—either to your toilets, irrigation system or both.

Best of all, our rainwater systems come with everything you need. The tank. The filters. The pumps. The whole shebang. And that means you don’t have to run all over town, searching for a pump here or a cistern there. To learn more about our rainwater systems, check out one of our most popular models.
