Which tank size is worth it in Vero Beach
Best fit: one 55-gallon barrel, which delivers about 150 gallons to the garden in a normal year (83.6% of its need).
If you buy one, a 55-gallon barrel with a downspout diverter is the whole job. Check that the overflow points away from your foundation, because most of Vero Beach's roof water will pass straight through it.
