ADVANTAGES OF RAINWATER
COLLECTION
 Texas rainfall patterns
historically tend to be inconsistent. Quite often wet
years are following by dry ones. Rainwater collection
systems need to be designed to capture sufficient amounts of
water to meet a family's needs during the dry years.
In conservative households the average gallons per day
individual falls between 25 and 40 gallons. Utilizing
this information enables one to calculate the size of roof
area and tank capacities needed.
The net return of one inch of rain on one square foot of
roof equals .6233 gallons. Consequently, a one inch of
rain on 1000 square feet yields 623 gallons. During
the calculation phase, one must remember that the roof area
can only be calculated by the roof footprint (square footage
of the area under roof). Square footage calculated due
to roof pitch will not increase the amount of return.
Rain water is virtually mineral free. This advantage
means less water heater problems, as well as less
showerhead, commode and faucet aerator repair.
Soap and detergent use is significantly reduced resulting in
lower phosphates in gray water.
