Why Harvest Rainwater with Rain Barrels?
Besides helping the environment, an obvious reason for harvesting rainwater is to save money. Depending on the size of your house and the amount of rainfall in your area, you can collect a substantial amount of rainwater with a simple system. This extra water can have a significant impact on your water bill. The use of rainwater combined with the domestic use of grey water can further increase your savings. Even if you live in a rural area and have your own well, the fact that rainwater is a naturally soft water may be enough to justify harvesting rainwater. (Keep reading for information on how to calculate the potential volume of rainwater you can collect.)
Rainwater stored in rain barrels has many uses. Some people find it mostly useful for watering their landscapes and gardens. Others find uses within the house as well. Rainwater can also be used for drinking but requires special treatment with a filtration system. Note that many cities require the filtration system for drinking water to be certified and the water to be tested on a regular basis. You do not need a filtration system for landscape uses. You can use it directly from your rain barrel on your garden.
If you’re harvesting rainwater with rain barrels to use for watering your landscaping, the rainwater can help to improve the health of your gardens, lawns, and trees. Rain is a naturally soft water and devoid of minerals, chlorine, fluoride, and other chemicals. For this reason, plants respond very well to rainwater. After all, it’s what plants in the wild thrive on!
