A household drinking water from single-use plastic bottles goes through a lot of plastic over a year. Reusable 5-gallon and 3-gallon jugs are a simple way to cut that down.
Here's how it works with home delivery: we drop off full jugs and pick up your empties on the next run. The jugs get cleaned and refilled, not tossed. It's the same basic model the old-school milkman delivery service ran on, just applied to water.
Beyond the plastic angle, it's just less hassle, no trips to the store, no recycling bin overflowing with bottles, no lifting cases out of a shopping cart.
If you're already rethinking single-use plastic in other parts of your routine, water delivery is one of the easier swaps to make.
