Rain Wealth not Waste with Rain Barrels and Rain
Gardens
Homeowners in the Rock River Basin can preserve
water quality - a few buckets at a time - and beautify their property
at the same time by either saving rain in rain barrels or by constructing
a rain garden.
Our grandparents, and many of us can remember
the familiar image of an old oak whiskey barrel by the side of the
house or the cistern in the basement. Well these old ideas are new
again, but without the mosquito concerns of the past or the need to
dip the water out with a bucket.
Instead of viewing the clean rainwater rushing
off our roofs as something to get rid of as quickly as possible, many
folks are taking advantage of this free resource. Capturing it and
using it to water flowers and lawns is particularly smart as rain
water is slightly acidic which flowering plants love. If you live
in the city this nice soft water doesn't contain salts, chlorine or
fluoride. An additional benefit is by using rain, you're not wasting
water that has gone through all the steps necessary to make it clean,
safe drinking water; water you've paid for through your utility bills.
In some parts of the country it is even illegal to use drinking water
for outdoor watering, in the Rock River Basin we often feel we are
awash in groundwater but that isn't true everywhere. In some areas
of the basin municipal, industrial and/or irrigation wells have significantly
lowered the groundwater table. Actions we can all take can both increase
infiltration while reducing harmful runoff.
Modern rain barrels use screens or other methods
to keep debris and mosquitoes out and have a handy spigot near the
bottom to fill a bucket or to attach a hose. You can even attach an
in-line pump and move the water easily throughout the yard. UW-Extension
has put together a 'Rain Barrel Sources of Southern Wisconsin' fact
sheet which has many different styles and prices of rain barrels ranging
from ones made out of 55 gallon plastic barrels to actual oak whisky
barrels and even attractive molded plastic commercial rain barrels.
For the hard core rain harvester, 250 and larger gallon plastic cisterns
are also available. The fact sheet can be found at www.rockrivercoalition/RRB/RRSG.asp.
A 55 gallon rain barrel, the standard size, can
catch about 2 tenths of an inch of rain, and of course if they aren't
emptied between rains, the next time they catch less. So they are
primarily used to turn rain into a resource for watering flowers,
trees , shrubs and lawns.
However one of the biggest reasons people are
being encouraged to put in rain barrels is to help reduce stormwater
from our urban areas. Rain water and snow melt rushing off of our
roofs, driveways and parking lots can be a big problem for our lakes
and rivers. The water is often contaminated with heavy metals, nutrients
and other chemicals. One solution is to grab this runoff before it
can hit the street, rush down the stormdrain and to the river, by
capturing it first in a rain garden, which is a slightly sunken perennial
garden that collects rainwater from a roof or paved area and allows
it to seep into the soil.
"Sometimes, people feel frustrated by complex
environmental problems because it seems there is little anyone can
do to make a difference," says Suzanne Wade, a University of Wisconsin
natural resources educator in the Rock River Town of Beloit portion.
"A rain garden, however, is something an individual can do protect
the environment. It is a way for people to do the right thing. And
the gardens are a beautiful addition to a home."
Rain gardens differ from ordinary perennial
gardens because they are planted in a shallow, flat-bottomed earthen
bowl. This bowl is then filled with native perennial flowering
plants. Popular choices include Sunflower, Black-eyed Susan, Liatris,
Gay Feather, Blue Flag Iris, Purple Cone Flower, Cardinal Flower,
and Golden Alexander.
