Rain Gardens Aid Louisville Waste Management

louisville msdWater has one consistent property that can cause problems. Water flows! This may seem pretty obvious, but many people may not realize the implications of this one property. Excessive water runoff can severely damage water sources. According to the Louisville Metropolitan Sewer District, rain gardens can aid waste management efforts.

How can a rain garden protect local waterways?

When there is excessive water runoff resulting from heavy rains and storms, this water absorbs chemicals, wastes, and toxic substances from the environment. When storm drains flood, this harmful water reaches local streams and waterways. Thus the local water, plant life and animals are all affected.

Rain gardens are designed to collect rainwater from the roof. Drainage lines are redirected from the normal channel into a nearby garden. The redirected flow is absorbed by plants and infiltrates into the ground. Water runoff from roofs diverted into Rain Gardens and Rain Barrels prevents storm water and pollutants from reaching storm drains, and eventually our streams and rivers.
