Rain water harvest is a great way to utilize natural resources efficiently and save some money on your water bill.

 

Some of the many uses for harvested rain water:

 

¨ Rain Gardens

¨ Irrigation water

¨ Stock water

¨ House water

¨ Supplemental in conjunction with well or municipal water

¨ Wash water (car, boat, RV, dog, etc.)

¨ Decorative pond

 

 

 

 

 

 

 

 

 

 

 

Yearly rainfall (in inches)  /  1.6 inches  x   sq ft roof area

=  gallons rainwater to collect per year

 

The average precipitation for  Washington County is 36.3 inches

 

Example of a decent sized barn or horse stable would be

             36.3” / 1.6 x 2400sqft = 54450 GALLONS of FREE water in one year!
