How much rainwater can your facility collect? 

Charlotte, NC typically receives 44 inches

of rain each year. By capturing the runoff

from a roof of 2,500 square feet, a company could gain 61,798 gallons of water each year.


Collecting rainwater minimizes your dependency on municipal water.

You can go green by harvesting rain¬≠water. And you can increase your bottom line while being environmentally active. While there's a growing emphasis on lessening environmental impact in commercial and government buildings, capturing rainwater is not a new concept; cisterns have been around for centuries. Your business can project an environmentally-responsible image with a rainwater collection system. It makes sense to harvest rainwater, both financially and environmentally. 

Rainfall is largely lost as runoff to streams, rivers, lakes 

and oceans.  Harvested, or contained, rainwater allows 

businesses to utilize additional water when municipal

water restrictions are implemented.  

Typical uses for harvested water include:

   - Landscape irrigation

   - Restroom water supply, laundry facilities

   - Cooling tower make-up water (evaporative systems)

   - Outdoor non-potable use

   - Fire protection

   - Drinking water

Water can be collected from these sources:

   - Roof water runoff

   - Site runoff, terraces, hardscape

   - Athletic fields

   - HVAC condensation

   - Parking lots and driveways 

In some areas, rainwater may represent the primary

source of water. Collected rainwater can augment

primary water sources and is a good standby in

emergency situations such as droughts or when

the well goes dry.
