Welded steel water tanks are a win-win proposition. They can be provided at low initial cost relative to other options, are less costly to maintain, and are very reliable. It is not unusual to find a properly maintained storage tank in operation which was installed 50 to 60 years ago.

At Phoenix elevated tanks are designed, fabricated, and built in accordance with AWWA standard D100 and other local codes including those codes regarding wind load, snow load, and earthquake preparedness.
