  • Description Description
  • Resources Resources

Fiber Glass Systems manufactures Flowtite® fiberglass tanks according to NSF 61 and AWWA standards for potable water storage. Because of their lightweight design, Flowtite tanks are easy to transport and easy to install making them popular in remote areas where a dependable, drinkable water source is critical. Fiberglass tanks can be manufactured to store potable water directly without liners or bladders common in both steel and concrete tanks.

According to the World Health Organization, less than 1% of the water on Earth is readily available for human use and consumption. With this finite supply of resource it is clear why conserving potable water is a key focus of green building projects.
