I’m thinking about adding a rain collector to use in my garden but I have some concerns about construction materials.
One concern is that I’m not a huge fan of using a plastic container to store water. The idea of water sitting in a plastic barrel that could be exposed to heat from direct sunlight doesn’t fill me with excitement. I was wondering what other materials or containers I could use that might be better for storing rain water. One idea I had was to modify a metal keg to collect water. They would be smaller but I could use multiple if I wanted.
The other concern I have is about roofing materials. Is it safe to use water collected from a roof with shingles in a garden for vegetables? I’m wondering if there might be any run off from the materials used for roofing.
Large collections of rainwater could disrupt water ecosystems. Admittedly, my comment doesn’t warrant much concern given the context OP’s post. Here is an article talking about Colorado’s water collection laws. Here’s a Reddit thread that offers some more information.
