Explanation / Answer

City dwellers consider installing barrels to catch and save rain water because rainwater can be used to water lawns and gardens.

Rainwater is preferred for soils and plants as it is cleaner and softer than most city water. Stored rainwater is used to irrigate the gardens which percolates through the soil and allows nature to clean the water. On the other hand, local water system degrades the water quality and indirectly hampers the soil and plants.
