What are the benefits of having a rain barrel?
A rain barrel is a container that collects and stores rainwater from your roof that would otherwise be lost to runoff and diverted to storm drains and streams. The water in a rain barrel is typically used to water plants, trees, shrubs and lawns. It will save you money! Lawn and garden watering make up nearly 40% of total household water use during the summer. A rain barrel will save most homeowners about 1,300 gallons of water during the peak summer months. It will help save the environment! Saving water not only helps protect the environment, it saves you money and energy (a decreased demand for treated tap water). It is better for plants and gardens because rainwater stored in rain barrels is a naturally soft water and devoid of minerals, chlorine, fluoride and other chemicals.
What are the benefits of having trees on my property?
The planting of trees means improved water quality, resulting in less stormwater runoff and erosion. This allows more recharging of the ground water supply. Wooded areas help prevent the transport of sediment and chemicals into streams. Landscaping, especially with trees, can increase property values by as much as 20 percent.
