Clean Water It’s Everybody’s 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 planet’s 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.
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 County’s 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 rainwateris 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.
Keep our Water COOL and CLEAN!
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 site’s 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 LIDsstop stormwaterrunoffbefore it leaves the site.
Structural LIDsstop stormwater-related impactsafter 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
Examples of Structural LIDs • Bioretention (Rain Gardens) • Capture Reuse • Constructed Filter • Detention Basins • Infiltration Practices • Native Revegetation • Pervious Pavement with Infiltration • Planter Boxes • Riparian Buffer Restoration • Soil Restoration • Vegetated Filter Strip • Vegetated Roof • Vegetated Swale • Water Quality Devices
We otter work together to plan for stormwater.
