How Much Rainwater Can a Roof Collect? This Small Roof Produces 7,400 Gallons
How Much Rainwater Can a Roof Collect? This Small Roof Produces 7,400 Gallons A simple rainwater harvesting calculation shows how an 825 square foot roof can collect thousands of gallons during the spring-to-fall rainy season. Starting With a Simple Goal The homeowner’s motivation was simple. “I just wanted to use more of the rain that’s […]
How Much Rainwater Can a Seattle Roof Produce? A Real RainWise Home Example
How Much Rainwater Can a Seattle Roof Produce? A Real RainWise Home Example Many homeowners underestimate how much water falls on their roof each year. In Seattle, consistent rainfall means even a modest roof has significant rainwater harvesting potential. Understanding Seattle rainfall, roof rainfall, and how water moves across a property is the first step […]
The Deviator (Patent Pending)
The Deviator (Patent Pending) Redefining where rainwater redirection begins. Most homeowners assume rainwater capture begins at the downspout. The Deviator (Patent Pending) introduces gutter-level rainwater redirection as a defined control point within a gravity-based rainwater system. By establishing roof runoff control at the gutter — before vertical descent begins — it repositions where coordination occurs […]
How Do Rainwater Incentive Programs Quietly Shape the Systems We Build?
What Incentive Programs Get Right — and What They’re Quietly Shaping About Rainwater Systems Incentive programs do more than reimburse hardware. They shape what gets built, how systems behave over time, and whether rainwater projects deliver stormwater and GSI outcomes in the real world. By Product Water — gravity-first rainwater system designers in Seattle. Incentive […]
Why Did the Rain Barrel Fail — and What Does That Reveal About Scalable Rainwater Systems?
Category: Rainwater Harvesting Case Study · Non-Vertical Hydraulics · System Thinking Executive Summary Why do so many rain barrels “fail” — and why does that failure repeat so consistently across otherwise capable homeowners? This case study examines a Seattle single-family home where a non-performing rain barrel became the diagnostic signal for a much larger insight: […]
What Incentive Programs Get Right
Most rainwater conversations start with tanks, rebates, or equipment. But the real reservoir is upstream. This piece explores how incentive programs shape the way we think about water—and why reframing rainwater as a site-wide system, not a standalone object, leads to more resilient and useful outcomes.
Designing with Water: Why Rain Systems Belong in Every Landscape Plan
How architects and design–build firms can turn water management into a design asset By Product Water — Think Outside the Tap In every project, the landscape tells a story — about material choices, ecology, and how people connect with place.But there’s another story, often invisible beneath that surface: how water moves through it. For too […]
Why Gravity Is Your First Pump
Understanding Low-Pressure Design in Home Rainwater Systems Why Gravity Is Your First Pump: Rethinking Rainwater Pressure By Product Water — Think Outside the Tap Most homeowners who start exploring rainwater harvesting think in terms of parts — tanks, hoses, fittings, and pumps.But a rainwater system isn’t just a collection of components; it’s a living hydraulic […]
