V- CSW is the way to go.
In my book magnets on an elevated structure is just a bad idea. I know we have expelled a ton of bandwidth in the past on this subject but I would look at how it would reflect in court if I had an issue. I would not put anything on a tank I could not repel (descend) from. Do it and do it right. Don't take chances and don't reinvent the wheel. You can purchase heavy duty tank tripods from Site Pro 1 (www.sitepro1.com) and get someone to install them for ya. I am sure the water authority's engineering staff would also approve the CSW mwthod faster.

Are the magnets the best (most cost effective) way of completing this type of install? Or is capacitive discharge stud welding going to be the better route?
