Backyard Conservation: Rainwater Harvesting

Rainwater Harvesting
Dakota County typically receives approximately 30 inches of precipitation per year on average, ranging from sporadic to more evenly spaced rainfall events. Rainwater harvesting is the practice of collecting storm water runoff from impervious surfaces such as roof or driveways and storing it for future use. The collection of rainwater can reduce runoff volume (curbing erosion issues downstream) and it can reduce the use of water pumped from aquifers by using the stored water in-between rain events. Rainwater harvesting can range from a downspout connected to a rain barrel to a collection pond connected to a storm water irrigation system.
