Essentially, the five most important things that a water tank must accomplish are:

1	It must invariably and continuously protect the quality of the drinking water it stores.
2	It must continually maintain the same qualities it was initially built with (earthquake-proof, hygiene, etc.).
3	It must continually maintain superior safety and durability qualities and must be simple in terms of management and maintenance.
4	It should have all of the convenient accessories required to properly increase its performance.
5	It must meet the highest standards in terms of the technology being used and be in strict compliance with all of the laws governing it.
