EVERY DROP The rainwater playbook

EVERY DROP: The Rainwater Playbook The Advanced DIY-Builder's Field Manual The rain that lands on your roof is a resource most people watch run down the gutter and disappear. This book shows you how to capture it, store it, and put it to work — from your first rain barrel to a system that keeps water flowing when the grid and the city main don't. Written for the serious do-it-yourselfer, Every Drop takes you all the way from the science of a single raindrop to a fully engineered, code-aware system. No fluff, no prepper hype — just the real numbers, materials, and methods a working builder needs. Inside you'll learn how to: Calculate exactly how much water your roof can yield, using real U.S. rainfall data for major cities and climates Choose the right tank size, foundation, and material — with true dimensions, weights, and capacities Select and size your piping (PVC, CPVC, PEX, HDPE), calculate pressure and elevation head, and run the line from tank outlet all the way to the tap Build a complete treatment train — from garden-grade screening to certified, drinkable potable water Install backflow prevention correctly and keep your harvested water safely separated from the public supply Diagnose and fix the common problems — algae, sediment, odor, low pressure, chemical balance — before they cost you Design for emergencies, so you have water when everyone else doesn't
