Always consider the overflow on any rain catchment system; there will always be overflow. On this site, we are capturing rain water in two 275 gallon tanks and two 55 gallon barrels for a total of 660 gallons of captured rain water. The overflow from these tanks and barrels, as well as another gutter on the front of the house, all spill into a dry creek that runs through the front yard and allows the water to disperse into the landscape. The dry creek has check dams in it to slow the water, and eventually ends in a rain garden, to hold even more water. We believe it is imperative to prevent rain water from spilling into our sewers and eventually rivers and creek. By capturing water in our landscapes, we can mitigate flood potential, as well as drought proof our landscapes and grow abundant food and beauty. It’s win, win, win, win, win….
