# **Rainwater Harvesting in **Seattle

## **Eco-Friendly, Off-Grid Independence—Filtered Right at the Roof **

Rain is one of Seattle's most abundant natural resources. So why waste it?

## **Smart Water Collection Starts at the Roof **

With a properly designed **rainwater harvesting system**, you can collect, store, and reuse rain for irrigation, flushing toilets, washing vehicles, and more. In some setups, with advanced filtration, it can even be treated for potable use.

But here's the truth: **your system is only as good as your first line of filtration.** And that starts at the roof.

**That's why we recommend ****MasterShield® as the ideal prefilter**** for any rainwater harvesting or cistern-based system. **

## **Why MasterShield Works So Well for Rainwater Harvesting **

Most rain catchment systems rely on a first-flush diverter or barrel screen to filter out debris. But if you're already pulling sludge and grit off the roof, you're starting dirty—and adding unnecessary wear to your filters, tanks, and pumps.

**MasterShield® fixes that by stopping contaminants before they ever leave the roof. **

__

### **Surgical-Grade Micro Mesh**

Filters particles as small as 50 microns—that's smaller than most pollen, grit, or moss spores.

__

### **Copper-Infused for Algae Control**

Copper thread woven through the mesh naturally kills algae, mildew, and moss—without chemicals.

__

### **Self-Cleans at Roof Pitch**

Installed to match the slope of your roof, MasterShield sheds organic debris before it can rot and leach into your cistern.

__

### **Reduces Maintenance**

Less gunk in the tank = less cleaning, less downtime, and longer lifespan for filters and pumps.

## **How It Works With Cistern Systems **

Here's how MasterShield plays into a rainwater harvesting system:

__

**Step 1**

### **Rain Hits Roof**

MasterShield immediately filters out leaves, grit, pollen, and moss.

__

**Step 2**

### **Clean Water Flows**

Clean water flows into your gutters, then through a screened downspout into a first-flush diverter (if used).

__

**Step 3**

### **Storage System**

Water continues into your buried cistern or above-ground storage tank.

__

**Step 4**

### **Distribution**

From there, water can be pumped to a filtration hub, garden, toilet line, or greywater system.

### **The Result**

MasterShield acts as a **first-stage filter**, keeping your storage system dramatically cleaner from day one.

## **Smart, Sustainable, & Scalable **

Whether you're trying to:

__

### **Cut Your Water Bill**

Reduce dependency on municipal water with collected rainwater for non-potable uses.

__

### **Grow a Garden Off-Grid**

Perfect irrigation solution for sustainable gardening and landscaping projects.

__

### **Reduce Storm Drain Load**

Keep rain from overloading storm drainage systems while capturing valuable water.

__

### **Water Independence**

Gain more control over your water usage with your own collection system.

…a rainwater catchment system with **MasterShield up top** sets you up for cleaner, lower-maintenance success.
