How It Works:

1. Rooftop rainwater flows through a downspout into the stone filled trough.

2. The water then spills over into planting containers where our special soil media and plants absorb contaminants.

3. Excess water from the planting containers overflows to the bottom water reservoir where water is released into the ground.

A Closer Look At StormGUARDen

How StormGUARDen GUARDs neighborhoods from flooding and GUARDs streams from stormwater runoff pollution

A rectangular box made of wood, wood composite or other durable weather resistant material, for the purpose of collecting rain water from a roof drain downspout. The device is lined with a reinforced polyethylene (RPE) or another impermeable liner, fitted with outlet orifices sized to control the outflow from the building roof. Water flows from the building downspout into a stone-lined trough, which directs flow from the downspout across the top of this device.

Below the trough are modular containers inserted into the rectangular box, which holds a stone storage layer providing plants with a long-term source of water during dry weather, and special soil media designed to remove pollutants from the roof runoff and support plant life. Water drains through filter media, before draining the storage compartment below.

Water leaves the device through small outlets sized for the roof (3 choices depending on roof drainage area). Water flows through the outlets to the surrounding ground, 10’ away from the home, or a connection can be made from the outlets back to the storm or combined sewer.

How do I figure out my roof size? Here are two options:

1. Use Google Earth, find your home and use the measure tool to measure the length times the width of the section of roof from the aerial view, draining to that downspout.

2. Uses the image below to help find your roof’s dimensions.
