People tend to have their preferred water drinking container, and normally fill and drink from that container once per day. I've seen recommendations for 96 oz for adult men, and 92 oz for adult women, or even some recommendations to aim as high as 128 oz (1 gallon). So you can use this one-glass per day to hack yourself into drinking more water by choosing a canteen/growler that holds the total amount of water you're aiming to drink every day. You might not always hit the mark unless you're making an earnest effort, but having a 1 gallon drinking vessel will cause you to drink more water.

And even if that seems like an extreme amount, getting at or close to that mark every day does make a difference for your health and how you feel.
