The Problem
The world is at risk to run out of clean
drinking water. Each flush of the toilet
wastes four to six gallons of clean drinking
water. Clean drinking water is also used
unnecessarily for outdoor uses (lawns,
gardens, etc.). This problem needs to be
solved.
We Have the Solution!
This problem can be solved by harvesting
rainwater to flush toilets and for outdoor
uses (lawns, gardens, etc.) instead of clean
drinking water. Rainwater needs to be
treated less than drinking water.
The idea is to broaden harvesting rainwater
from roofs of homes/businesses and store
it in tanks, put rain barrels in the city and
in yards. Communities could also put in
place buildings to collect / supply rainwater
to houses.
To broaden awareness, we are launching
the "Rain It In" campaign. We are
working paftnering with the Prior Lake
Watershed District and school naturalists to
raise money to buy rain barrels to give away
at the Spring Water District Clean-Up event.
For the Home:
There are multiple options for collecting
rainwater at home. A rain barrel or multiple
rain barrels can collect water for outdoor use
(for lawn, garden, etc.). For larger scale use
both indoor and outdoori a tank can be
installed.
For the Business:
For a business solution, a separate building
can be built for collecting and treating
rainwater.
These Minnesota businesses are examples of
where these types of rainwater harvesting
solutions are being used: CHS stadium in Saint
Paul, Target Field in Minneapolis, Eagle Valley
and Prestwick Golf Club in Woodbury
Minnesota.
For the Communitv:
For a community solution, a water storage
building can be put in place to collect water,
treat it, and then send the water to multiple
houses through separate pipes.
These Minnesota communities are examples of
where these types of rainwater harvesting
solutions are being used: Towerside District,
Hugo, and Shakopee Mdewakanton Sioux
Community.
How Does This Solution
Help Our Community?
Our solution helps our community conserve
clean drinking water. Some fast growing
cities have been forced to import water due
to underground aquifers not being able to
meet demand. The Ogallala aquifer, for
example, has been over pumped to the
point that one fourth of the reserve has
been depleted. We broaden awareness of
the benefits of harvesting rainwater (rather
than wasting clean drinking water) for
purposes such as flushing toilets and
outdoor uses.
Solution Pricing
Home: small $40-$1,000, large $3,000-$8,000
Business: small $300,00, large $1,000,000
Community: $1,000,000 or more
Most solutions payback in 2-5 years!

Did You Know?
1. Americans use 1274/o more
water than we did in 1950!
2. Older toilets (made before
1995) use more than 5
gallons of water!
3. One-third of the water used
for irrigation in the US comes
from aquifers beneath the
Great Plains between South
Dakota and Norwest Texas.
4. The Ogallala aquifer has been
over-pumped to the point of
619-quarter of the reserve
has been depleted.
5. Wells have to be dug deeper
and deeper to reach the
water. Eventually the wells
will be so deep the water will
be too salty to be used.
6. Some fast-growing cities
have been forced to import
water or pump more water
from underground aquifers
than nature can replace.
7. For every 100 gallons of
water used in the world, 70
gallons irrigate farmland.
8. Only 30o/o of freshwater
comes from underground
sources.
9. Canada contains one-fifth of
the world's freshwater.
