Getting water to drain and replenish groundwater can’t be done if it’s in a bucket. Not that this sort of replenishment is happening at a good rate, civilization has done a number on the systems which replenish groundwater.

Moreover, you greatly underestimate the amount of water you’d need to store. A residence will consume around 100 gallons of water per day, per person. Storage of rainwater at that scale is simply unreasonable for most areas.
