Water-wise gardening is three habits and some hardware: put water at the root zone instead of into the air, cover bare soil so it does not evaporate, and catch what falls on the roof before it runs to the street.

Drip emitters rated in gallons per hour deliver about ninety per cent of what they release to the plant, against roughly half for an overhead sprinkler on a hot afternoon. Two to three inches of mulch does the rest.

For scale: one inch of rain on a 1,000 square foot roof is about 600 gallons. A barrel needs a screened inlet, an overflow routed away from the foundation, and a level load-bearing base, since 55 gallons weighs over 450 pounds. A few states still regulate rainwater collection, so check locally.
