Which tank size is worth it in Bay Village

Best fit: one 55-gallon barrel, which delivers about 291 gallons to the garden in a normal year (76.0% of its need).

Before you buy, a 55-gallon barrel with a downspout diverter is the whole job. Check that the overflow points away from your foundation, because most of Bay Village's roof water will pass straight through it.
