Xerxes Fiberglass Tanks: For All Kinds of Water Storage Applications

We’ve written a lot over the past few weeks about how water and storage tanks just don’t play well together in a number of situations. But don’t get us wrong. Storage tanks that are specifically designed to hold water do a great job of it. And there are plenty of applications that require a tank designed for water storage. In this week’s blog, we’ll talk about Xerxes fiberglass storage tanks and the various water storage applications for which they can be used.

Xerxes Fiberglass Tanks: For All Kinds of Water Storage Applications

Why fiberglass?

Why is fiberglass the ideal material for water storage tanks?

  • Fiberglass is naturally resistant to corrosion, unlike concrete and steel, which need to be treated to protect against corrosion.
  • Fiberglass is non-porous, meaning there are no crevices in which bacteria can live and grow, creating problems associated with microbial growth. Concrete is porous.
  • Fiberglass is lightweight, making it easier and more affordable to ship and install anywhere.
  • Xerxes fiberglass tanks are equipped for on-site pressure testing before and after installation, ensuring they’re watertight.

Fiberglass Water Storage Applications

Potable Water

Potable water storage is a necessity at countless commercial, industrial, and governmental facilities. Xerxes fiberglass storage tanks are ideal for potable water storage because they can be manufactured to conform to the requirements of NSF / ANSI 61 – Drinking Water System Components – Health Effects.

In addition, fiberglass has an advantage over steel and concrete in potable water storage because it doesn’t require an internal liner to meet industry standards for potable water. These liners are usually difficult to maintain over the life of the tank.

Fire Suppression

Fire suppression storage tanks are used mainly in rural areas that don’t have access to a widespread municipal water system. Fiberglass tanks are ideal for storing water for fire suppression for a number of reasons. The tanks are watertight resistant to corrosion, reducing the likelihood of leaks. Plus, the lightweight nature of fiberglass tanks makes them easier to transport to remote locations were fire suppression is needed.

Rainwater Collection

Rainwater collection is the practice of collecting rainwater and storing it for use in a facility. A common example is rainwater that is captured and stored for use as greywater for flushing toilets. Learn more about some greywater projects we’ve done in our blog.

Stormwater Retention

Stormwater retention is the practice of collecting water from storms that would otherwise collect as runoff. Runoff has a number of negative effects on the environment, including erosion and depositing of sediment and chemicals in watersheds. Fiberglass storage tanks can be used to collect this water, attenuate it, and slowly release it into the environment to prevent runoff.
