Barrel or cistern in Snyder?

Best fit: 2 linked 55-gallon barrels, which delivers about 1,569 gallons to the garden in a normal year (87.9% 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 Snyder's roof water will pass straight through it.
