Growing up, my family subscribed to a monthly (or maybe semi-monthly?) service where a Poland Spring truck would deliver multiple 5-gallon jugs to our home. We usually kept them in the garage and then when the old jug was empty, one of us had to overturn one of them onto the water dispenser that was no more than a bowl with a spigot that sat on top of a tall wooden base.
Living in New England, the winters got cold enough for the jugs to freeze solid even if they were sitting in the garage. Water expands as it freezes, so this caused multiple bottles every year to crack open or in some cases shatter their plastic all over the concrete garage floor.
I hated it.
I don't know if this all began because my parents had lived in apartments where the water was coming through old lead pipes or because my mom might be a super-taster and hated the flavor of the tap or maybe something had gone wrong with the water treatment in my town and we were afraid of toxic chemicals? At any rate, we had these jugs, and from a time when I still had to balance them on my shoulder for support while replacing them until about midway through college, we did this routine of having a jug become empty and then no one wanting to replace it and then eventually someone bringing a new one in and spilling (hopefully only) some of it on the floor in the process of turning it over.
To replace the jug, the spout at the top had to fit within the roughly 6-inch diameter circle of the water dispenser. The lip of the spout was too thick to poor water from slowly: the adhesion would make the stream cling to the plastic and run down the side and then onto the floor. This meant there was no way to slowly and deliberately replace the jug to make sure everything was aligned correctly. Instead, to avoid spilling, it was important to go as quickly and confidently as possible. This often had the opposite effect of spilling water on the floor from not being aligned properly at pouring time. It seemed like a system specifically designed to be difficult.
Once I went off to college, I often came home with new perspectives. I began drinking water filtered through a roommate's Brita, or from a filtered dispenser in the cafeteria, or just straight from a tap more regularly. I became more conscious of the climate impact of having a gasoline-powered truck driving plastic hundreds of miles just for my parents to get water through this convoluted system that I hated. I had become aware of the cost of this subscription model that over the decade or more of use could have probably replaced the incoming water pipes in the house with new ones.
I wound up recommending to them that they get a water filtration system installed for the tap. It was a few hundred dollars, but it seemed worth it to get rid of the jugs in the long term. A few months later, they did just that. And for several years from then until they moved out of that home, every time I'd come home they'd mention how glad they were that I convinced them to switch over.
