And now for the Environmental Benefits of Rainwater Harvesting...
April is Earth Month. What if doing your part could be as easy as installing a few rain barrels?
You've heard rainwater harvesting is good for the environment, but if you're like most of us, you don't know exactly why.
Here are a few quick points followed by some key details for why rainwater harvesting is absolutely vital for making your local ecology thrive.
Did you know that rainwater harvesting is a great way to:
- Protect your local watershed;
- Drought-proof, flood-proof, and fire-proof your garden;
- Restore the hydrologic cycle;
- Recharge groundwater;
- Reduce your carbon footprint;
- Maintain healthy soils;
- Keep your garden lush and healthy;
- Lessen the effects of wet and dry spells;
- Mitigate impacts of climate change;
- Utilize recycled materials (a given, if you choose BlueBarrel!)
The environmental benefits of rainwater harvesting are are many!
Most of us know that rainwater harvesting is good for the environment, but we need a little help articulating why. Here are some of the major ways you align with Mother Earth when you capture rainwater for on-site use:
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.
Restore the Hydrologic Cycle
(Reduce Stormwater Impacts & Recharge Groundwater)
In a natural landscape, approximately 50% of stormwater infiltrates into the ground, 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 for 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 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!).
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 hardscapes, 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.
Reduce your Carbon Footprint
(Mitigate Climate Change by Reducing Energy Use)
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.
Increase the Health of Your Garden
(Mitigate Climate Change with Healthier Plants & Soils)
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 garden ecosystem, while the earth benefits from all that a healthy garden provides... including cleaner air, carbon sink, pollinator habitat, and more!
