North Carolina Considers More Rainwater

The North Carolina building code prevents homeowners from using rainwater in their homes for anything besides irrigation. So what are some of the banned uses for this free water?

1. Rainwater for your Toilet. Typically, 25% of your water uses is literally flushed down the toilet. What if you could you rainwater to flush your toilet? Here is a cool how to guide that I have on my “when I have time” projects.

2. Rainwater for your Washing Machine. Washing clothes represents 20 percent. I am not sure if I am ready to try this, though.

Together both of these uses would represent 50% of indoor water use using this resource. Not too bad.

North Carolina is currently considering altering its building codes to allow expanded use of rainwater. If the proposal goes through, the new code takes effect in January. I am not sure if similiar impediments exist in other Southeastern states.

  1. Watercrunch, not only do Florida codes prohibit capturing rainwater for flushing, but many communities — and especially homeowners’ associations — outlaw cisterns in Florida. They are considered eyesores, the same way brown lawns are considered eyesores, even during times of drought. Last year I toured a green building in Sarasota County where the health department had allowed rain-water toilets, but required a sign over each commode that says: “Not for human consumption.” Hey, at least the health department okayed the toilets! I’ll email you a photo.
