Environmental Benefits of Rainwater Harvesting

April is Earth Month. What if you could make a big difference just by installing a few rain barrels?

You've heard rainwater harvesting is good for the environment, but if you're like most, you can't explain exactly why.

Here are a few quick points followed by some key details for why rainwater harvesting is absolutely vital for making local ecology and the global water cycle thrive.

Environmental Benefits of Rainwater HarvestingRainwater harvesting is a great way to: 

  • Protect your local watershed;
  • Make your garden more resilient in the face of droughts, floods, and fire;
  • Restore the hydrologic cycle;
  • Recharge groundwater;
  • Reduce your carbon footprint;
  • Maintain healthy soils;
  • Keep your garden lush and healthy (which, in-turn, enriches habitat and helps to regulate local temperatures and precipitation);
  • Lessen the effects of wet and dry spells;
  • Mitigate impacts of climate change;
  • Utilize recycled materials (a given, if you choose BlueBarrel!)

Environmental Benefits of Rainwater Harvesting Explained

Most of us know that rainwater harvesting is good for the environment, but we need a little help articulating why. Here are five major ways you align with Mother Earth when you capture rainwater for on-site use:

 

1. Reduce your Draw on Stressed Systems

Aging water infrastructure is expensive to update; and groundwater and reservoirs are often overdrawn. When you supply a portion of your own water from the rain that falls on your roof, you reduce your draw on these stressed systems.

 

2. Restore the Hydrologic Cycle (a.k.a Water Cycle)

(Reduce Stormwater Impacts & Recharge Groundwater)

Environmental Benefits of Rainwater HarvestingIn a natural landscape, approximately 50% of stormwater infiltrates into the ground, hydrating soils and recharging groundwater. About 40% evaporates, and only 10% runs off.

In developed landscapes, by contrast (e.g. our neighborhoods); only 15% infiltrates and a whopping 55% runs off! This is because water can't penetrate hardscape (roads, rooftops, parking lots, etc...).

When you collect rainwater to use in your garden, you reduce stormwater impacts by holding water on-site rather than letting it run off. As you release it later (when the ground is no longer saturated), you allow that water to sink back into the ground where it belongs, hydrating soils, nourishing plants, and recharging the groundwater beneath us. In other words, you restore the broken infiltration link in the hydrologic cycle.  If you've heard the mantra: Slow it, Spread it, Sink it, Store it! that's what we're talking about here (as opposed to Pump it, Pipe it, Pollute it!).

3. Protect your Local Watershed

(Reduce Pollution & Erosion)

When rainwater infiltrates onsite, it is filtered naturally by the earth, and is prevented from entering storm drains and surface waters as polluted runoff. Left unmitigated, rainwater sheets off roofs and paved surfaces, collecting contaminants along the way. When stormwater runs heavy, it causes stream banks to erode as well, causing further damage to our sensitive waterways and wildlife habitat. According to the EPA, stormwater runoff is the number one source of pollution in the USA. When you Slow it, Spread it, Sink it, Store it on your site, you prevent this from happening.

 

4. Reduce your Carbon Footprint

There is a strong nexus between energy and water in our modern world. In the state of California, for example, heating, treating, and transporting water accounts for over 20% of per-capita energy use! When you reduce your reliance on pumped and treated water sources, you contribute to a collective savings in energy at the same time.

Better yet, if you pair your rainwater catchment system with a user-friendly gravity-fed drip irrigation system, you don't need any electricity at all to run your irrigation.

 

5. Increase the Health of Your Garden

It's no coincidence that plants love rainwater better than any other water source. Not only is rain free of the salts, chemicals and minerals found in other water sources; by nature's design it has the perfect pH balance and nitrate delivery, ready for uptake by your thirsty garden.

Benefit from the beauty of a healthy plant and soil ecosystem, while the earth benefits from all that a healthy garden provides... including cleaner air, carbon sink, pollinator habitat, temperature and precipitation regulation, and more!

 

The Deeper Why: How Rainwater Harvesting Heals the Earth

We just threw a few biggies at you, so let's break down some of these environmental concepts a little more. What do we mean by temperature and precipitation regulation? Here's where we can really start to understand the interconnected nature of Earth's vital systems, and why carbon reductions alone do not address the deepest roots of climate change.

Have you heard of the urban heat island effect? Temperatures in urban areas are significantly warmer than in immediately surrounding natural areas because dark rooftops and pavement absorb extra heat that then radiates back into the environment. The more we can vegetate our towns and cities, the more we will regulate temperatures. Vegetation in urban areas also helps to improve air quality.

And precipitation regulation? Believe it or not, a lush garden will actually make rain. Get this: plants evapotranspirate, meaning they uptake water from the soils, and emit water vapor into the sky, which contributes to cloud formation. Plants also release bacteria that form "water nuclei" that attract water molecules to form rain drops. Plants ask mother nature for a drink, and she provides. Between adding more moisture to the atmosphere and sending up water nuclei to ask for rain, a landscape of lush gardens will summon more rainfall than a parched one.

Just imagine: by tapping into the otherwise-wasted water source that comes from your roof, you can create abundance in your own backyard. If others do the same, we collectively have the power to bring vitality back to an ailing environment.
