| Use Your Commercial Building as a Rain Water Collection System|
|It is amazing how much water is wasted and never retained by municipalities or County governments during large rainfalls. There are often storms which dump 2 to 3 inches of rain in a region and what people don't understand is that a large parking lot at Walmart could collect well over 1.5 million gallons of water during a storm that size. And that's just the parking lot. Obviously parking lots have dirty water, but parking lots could employ strategies of having vegetation and retention basins which allow the rain runoff to percolate into the groundwater - indeed some do.|
Now then, let's discuss the amount of water that could be collected from the roof. A storm the size of 2 to 3 inches will put well over 75,000 gallons of water on top of a Walmart retail store. That's a lot of water, and it should not be wasted. That amount of water is enough to water all the shrubbery, and grassy areas of a major shopping center, thus, it ought to be collected. Of course there is a right way and a wrong way to collect rainwater using superior rain gutter systems. You see, often debris flows onto the roof and gets in the way of the downspouts.
A truly efficient rain gutter system would prevent this from happening, and in doing so it could remain efficient and have proper water flows which would not clog up the watering system that the rainfall catch containers used as their water source. We should be collecting all of the water that falls onto commercial buildings, and onto the buildings of government agencies. We should be collecting the water at airports, which runs off of hangers, as well as any and all water that runs off of carports. And we should do it in a cost conscious manner. Please consider all this.
