Rain Barrels

Why use rain barrels?

What is green stormwater infrastructure? 

Some common examples of GSIs are:

All of these solutions divert and utilize stormwater from precipitation in unique ways. Reducing the amount of harmful runoff created by man-made structures, impermeable roads, and agricultural fertilizers is key in GSI program's ability to affect water quality. GSI can be scaled up or down depending on community needs and application. Green roofs may not be viable in smaller communities but residential rain barrels may benefit the same residents in saving on water costs (EPA, n.d.).

Globally

A rain barrel is something that can be taken advantage of by anyone. Water conservation is a main reason why people may want to set up a rain barrel, as they could use the water on anything they'd like. However, globally, rain barrels may be crucial in gaining access to free water in places where drinking water is highly privatized or difficult to access.

Nationally

A major benefit of using rain barrels nationwide would be reducing runoff pollution and erosion from large-scale agricultural practices.  Project Rain Barrel is a program that runs across the US and Canada with the goal of providing free materials and workshops to reduce homeowners' water footprint!

Locally

A rain barrel on a local scale can range anywhere from simply setting a bucket outside during rainfall, to highly sophisticated setups, such as the picture above. Localized rain barrels would be great for watering one's plants. The WMEAC rain barrel workshop is a West Michigan program that focuses on community education about GSIs!

WMEAC Rain Barrel Workshops

The West Michigan Environmental Action Council currently holds workshops to provide low-cost rain barrels and educate attendees on how properly set up and maintain the systems. Workshops include upcycled 55-gallon barrels and all necessary components for construction. 

Passive and Active Harvesting

Passive Rainwater Harvesting

Rainwater flow is captured from roof runoff through gutters and downspouts by gravitational pull. Collected water travels down the downspout to a barrel, cistern, or tank, typically with a 50-100 gallon capacity. Rainwater can then be accessed for irrigation or other agricultural uses through spigots and hoses on the lower portion of the tank. Passive rain barrels also usually include a screen to prevent insects or debris from entering the tank. 

Active Rainwater Harvesting

Rainwater is collected from roof runoff or larger sources (such as parking lots or roadways) in more industrial systems. Active systems have a larger water storage capacity, typically between 1,000-100,000 gallons, and contain pumps and electronic water level sensors to redirect water flow against gravity and allow water flow to other household uses. 

Limitations and Considerations

Rain barrels at the Sustainable Agriculture Project



To introduce more productive stormwater management practices at the SAP, two rain barrel systems can be added to the tool shed to save on irrigation costs. 

While gutters will create an initial overhead cost, these rain barrels will reduce the overall stormwater impact of the SAP while only being around $4.06 per gallon for the rain barrel systems themselves. 

This addition to the SAP could also become an effective teaching tool by allowing interns to decorate them, add QR codes to promote further education about GSI, and opening a dialog about DIY water diverting that can contribute to strong communal education
