Saving money on water is one thing I'm constantly monitoring. With the need to water pets, top off koi ponds and swimming pool, watering vegetable and flower gardens as well as laundry and bathing, our water bill can get expensive.
I've wrote about rain harvesting and using rain barrels before, but feel the subject is worth repeating and staying on top of new found ideas.
How much rain does it take to fill my system?
Not as much as you think. It is easy to calculate how much rainwater your roof generates. The constant to remember is: 1" of rain will produce 625 gallons of runoff from a 1000 square foot roof, or 625 gallons per 1000 square feet.
