I created this 20-gallon rain collection barrel from a 20-gallon trash can. I added a spigot to the bottom. To the lid, I drilled out two holes and flipped it upside down along with adding in two sink drain strainers. This allows for the collection of rainwater into the system. I can also fill it with excess water from the hose when draining it out. To the top, I added a rain barrel mosquito netting and Bungie cords to secure the netting in place.
