Gardening season has begun! Which makes now a great time to consider ways to make your garden eco-friendly. Rainwater harvesting should be on the list for consideration! This natural water source is beneficial for your plants. This is because it has micro-nutrients and doesn’t contain contaminants that can be found in tap water. As a bonus, it also helps to reduce stormwater runoff of polluted water from our urban surfaces into our natural waterways during heavy rainfall.
So how does rainwater harvesting work?
A basic rain barrel collects water from a downspout with a water outlet on the lower portion of the barrel. (Ensure you have a diverter for when the barrel gets full!). Elevating the barrel helps the water flow.
Some rain barrels also have an option to connect multiple barrels to collect more rainwater.
Rainwater Harvesting can be done anywhere!
If you live in a condo, rain harvesting can be as simple as placing yogurt containers near the balcony railing when it rains. When they are filled, put the lids on for storage.
Whichever way you collect rainwater, store it in a shaded spot. Also, use the water within a week or two of collection to prevent bacteria and algae growth.
Before getting started, you should also check to see if there are any restrictions for collecting rainwater in your area. In the City of Toronto, it is mandatory to have your downspouts disconnected from the sewer system. During times of heavy rain, the sewers can become overloaded. Which can increase the risk of basement flooding and the release of polluted rainwater into local waterways. Redirecting the stormwater on to your own property alleviates the stress on the City’s sewer system. Rain barrels are encouraged by the City and area a great way to make good use of that water!
Also note that since it’s not treated, it shouldn’t be consumed. If you are watering edible plants, water the soil only. Not the plant itself! Together, with water-saving measures such as installing low-flow faucets and toilets, collecting rainwater for your garden is another way to help preserve one of Earth’s most valuable resources and it can also help cut down your water bill.
