Saves on the expense of water plus sewer surcharge Environmental consideration due to combined sewer overflow, sedimentation, and pollution runoff Water may be better for plants Make a “visible” environmental statement Why Collect Rainwater?
Amount of water needed to make a bottle of water Water required per pound of beef Percentage of water that goes to irrigation Percentage of corn grown with irrigation How far from Louisville to Fiji Amount of sugar in Vitamin Water compared to Coke Fun (and Scary) Water Facts
Amount of water needed to make a bottle of water (2 bottles) Water required per pound of beef (450 to 2500 gallons) Percentage of water that goes to irrigation (37%) Percentage of corn grown with irrigation (20%) How far from Louisville to Fiji (7400 miles) Amount of sugar in Vitamin Water compared to Coke (33g vs. 39g) Fun (and Scary) Water Facts
Should be close to the bottom of barrel Should be large opening for maximum flow Tight joint in barrel Can use bulkhead fitting Use valve that has hose thread built in Outlet
A higher stand gives more pressure 1 psi of pressure for each 2.3 feet of height Stand needs to be level so barrel will balance Certain barrels are more prone to tipping Consider securing barrel to wall for safety Rainbarrel Stands
A rain garden is a planted depression that allows rainwater runoff from impervious urban areas like roofs, driveways, walkways, parking lots, and compacted lawn areas the opportunity to be absorbed Definition of Rain Garden
Size is primarily function of roof area Also should consider soil permeability Percolation test can be performed Rule of Thumb………30% of the roof area At least 10 feet from house Natural low spot……….or dig a hole Sizing and Placement of a Raingarden
Often use native species Wet loving plants in the bottom Dryer plants at the edge Pay attention to sun/shade requirements Species available from local sources List of Native plants in MSD pamphlet Plants for a Rain Garden
Swales Think of a swale as a linear raingarden Plants are often planted on the lower berm Swales are usually constructed along contour lines A contour line is a line in which each point is the same elevation above sea level
Bioswales Bioswales are landscape elements designed and built to remove silt and pollution from surface runoff water. These “swaled” drainage courses are, in a sense, gently sloped ditches that contain plants, compost and/or riprap. The sloped sides are usually less than six percent slope. These are often constructed of “engineered soil”.
Bioswales Think of a bioswale as a raingarden in which the water has a “destination”. Although designed to slow, clean, and cool water flow, they are not designed to strictly infiltrate the water into the soil.
