One of the things planned for the new front porch was a place to put a rain barrel. Given the weather patterns here in California (rainy winters, dry summers), there's a limit to the usefulness of a barrel as it won't get refilled from roughly May to October, but every little bit helps. Today I cut the downspout and added an elbow to get it ready.
Eventually I'd like to have a big tank under the deck that gets fed from multiple downspouts, but for now I'll have to settle for this 50 gallon one. It should get its first test Saturday night, and the overflow system some time after that as the forecast has rain on and off all next week.
