Clean Water Its Everybodys Business
From a distance we might get the impression that our planet has an unlimited supply of clean water available to use.
In Kalamazoo County, it is hard to imagine that we could ever run out of fresh water.. Because 20% of our planets supply (90% of the US supply) is right here.
BUT looks ARE deceiving. The little blue sphere represents ALL the water on Earth. (Diameter 860 miles=Salt Lake City to Topeka)
Of ALL water on Earth, only about 0.007% is economically available for human use.
Thats not much.
The SUPPLY of available water is DECREASING because of rainwater contamination.
Meanwhile, DEMAND for available water is INCREASING at the same time the SUPPLY of available water is DECREASING.
For this reason, clean water is Kalamazoo Countys most valuable resource. It will continue to become increasingly more valuable in the future.
And just like caring for any physical system, (car, body, house, etc) prevention is many more times more cost effective than treatment.
EPA studies show that up to 70% of all water pollution is caused by stormwater runoff.
Drains carry stormwater runoff from our homes and businesses to our lakes and rivers.
Storm water = Rainwater + Pollution The major pollutants are: Sediment Hydrocarbons Salt Bacteria Trash Heat
The solution to the pollution of rainwater is to not let rainwater gather volume and speed. This can easily be achieved by immediately capturing, filtering, cleaning and storing it as close as possible to where rain falls.

COOL and CLEAN! Keep our Water
Low Impact Development (LID) is a powerful strategy that Kalamazoo County can use to keep our waters clean. There are lots of options to choose from.
The GOAL of Low Impact Development (LID) is to recreate a sites presettlement hydrology by using designs that:
infiltrate, filter, store, evaporate, and detain (Make bullets look like raindrops) stormwater runoff close to its source.
There are two kinds of Low Impact Development (LID): Non Structural and Structural
Non-Structural LIDs stop stormwater runoff before it leaves the site.
Structural LIDs stop stormwater-related impacts after they occur.
Examples of Non-Structural LIDs Cluster development Minimize soil compaction during construction Minimize total disturbed area during construction Protect natural flow pathways Protect riparian buffers Protect sensitive areas Reduce impervious surfaces Stormwater disconnection
