A basic rain barrel collects water from a downspout (ensure you have a diverter for when the barrel gets full) with a water outlet on the lower portion of the barrel. Elevating the barrel helps the water flow. Some rain barrels also have an option to connect multiple barrels to collect more rainwater.
For condo balconies, rain harvesting can be as simple as placing yogourt containers near the balcony railing when it rains, and when it’s filled, put the lids on for storage.
Whichever way you collect rainwater, store it in a shaded spot and use the water within a week or two of collection to prevent bacteria and algae growth.
Before getting started, check to see if there are any restrictions for harvesting rainwater in your area. 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, rainwater harvesting is another way to help preserve one of Earth’s most valuable resources and cutting down your water bill.
