Use less disposable plastic bottles
If you choose to use a water delivery service, you can get large, multi-gallon bottles, rather than (or in addition to) small plastic disposable bottles. A professional will set you up with a water cooler during your first delivery, and show you how to use it. You can still get disposable water bottles delivered as well, but you will not need them as much as you did in the past. It will save you a lot of room in your fridge, as the water cooler can provide you with either hot or cold water at any time.
If you have less of a need for using plastic disposable bottles, you'll be doing some good for the environment. Plastic waste is a major environmental problem around the world. Anytime you reduce disposable plastic usage, you are helping the environment.
No need to go to the grocery store for water
Have you ever found yourself needing to go to the grocery store simply to buy water? This will never happen to you again. This is one of the benefits of getting water delivered to your home. If you have a large family, you know how fast water can be consumed. You probably find yourself going back-and-forth to the store more times every week than you would like to.
No more lugging around heavy water
Once you purchase water from the grocery store, it has to somehow find its way into your home. This typically means lifting and transporting the water from your grocery cart into your vehicle and then lugging the water from your vehicle into your home. If you're buying cases of water bottles, or large, multi-gallon bottles, this heavy lifting will do a number on your body. Home water delivery services make it so you no longer have to do this.
Never run out of water
When you set up home water delivery services, you can do so in a way which will prevent you from ever running out of water again. Some companies will allow you to adjust each order based on how much water you still have left. If the delivery person shows up with two multi-gallon water bottles, and you only need one, they will simply adjust the delivery details, and only charge you for the one bottle you need.
When you use a water delivery service, you're able to purchase your water in larger amounts. This results in significant discounts compared to what you would pay for water at a grocery store.
