Which tank size is worth it in Kendallville

Best fit: one 55-gallon barrel, which delivers about 481 gallons to the garden in a normal year (80.0% of its need).

If you set one up, a 55-gallon barrel with a downspout diverter is the whole job. Check that the overflow points away from your foundation, because most of Kendallville's roof water will pass straight through it.
