I plugged my roof dimensions into the rainwater collection calculator on Gardenvoila with local rainfall averages. The potential was far more than my garden needs in a typical month, which made me rethink storage. I’m now considering a larger tank instead of just barrels.
Has anyone set up a larger system? I’d love to hear about first-flush diverters and what maintenance is really involved. I’m also wondering about winter, since freezing seems like a risk for exposed tanks.
