What size rain barrel for Satellite Beach
Best fit: one 55-gallon barrel, which delivers about 215 gallons to the garden in a normal year (84.5% 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 Satellite Beach's roof water will pass straight through it.
