When you are researching water delivery, there will be both small local companies and large national organizations that provide the service. Both can have varying levels of service, so it is important to do research before signing up long term. Ask your neighbors and co-workers who is the best company in your area, sometimes, different companies have different levels of service in different areas, so there isn’t always one “best water delivery service”. If you can’t find someone in your area who has water delivery, I would stick with one of the large national companies and ask if they have any sort of guarantee so that you can cancel without penalty if you are not satisfied.
Here are the top national water delivery companies and a few facts about each of them. The prices listed are the lowest prices I found for my local area for 5 gallon jug delivery, your prices may vary, and it also depends on whether you rent or buy your own dispenser. In my searches, I would expect to pay around $7/bottle/month. Generally, the more bottles you get per month, the cheaper the per bottle cost. If you agree to a long term commitment, it will also usually be cheaper. Some companies will give you a bonus for signing a contract, like a free cooler, a case of .5L bottles of water, or a storage rack.
