Potable Water How Different Storage Tanks Affect Its Specifications

Modular water tanks

It can be difficult to store water, whether it’s clean or contaminated. More recently, many municipalities have been making greater efforts to recycle water, cleaning wastewater until it’s reached proper potable water specifications. In Marcellus Shale gas country in PA, 70% of water is recycled — but that still leaves the rest to be disposed of. In the United States, there are an estimated 16,000 municipal water treatment facilities still being operated, and centralized collection and treatment systems serve about 75% of the American population. Recycling water makes this resource more sustainable, and in general is a much more environmentally friendly process than simply disposing of all wastewater. With that being said, the issue still remains of where water is to be stored during the treatment process, and for that matter of what material above ground storage tanks should be made of. Constructing large capacity water tanks is sometimes easier said than done, as the last thing a municipality wants to deal with is above ground storage tanks that are at risk of degrading. Above ground storage tanks need to hold water whether or not it’s reached potable water specifications — they need to be sturdy. Let’s look into the different types of above ground tanks available, and how they differ from one another.

What Are Above Ground Water Storage Tanks Made From?

Today, large water storage tanks are typically made from one of two main materials: concrete or steel. Of course, there are sometimes different materials used by differing companies, and the material from which a storage tank is made can depend on exactly what it’s being used for. An above ground water tank needs to be made of a material that contains water, while at the same time not further contaminating it. This can be a difficult balance to strike, and it’s further complicated by the fact that most municipalities are running on fairly tight budgets. Tanks may hold water before or after it’s reached potable water specifications, and can sometimes be a part of the treatment process itself.

What Is The Cost Of A Concrete Tank Versus A Steel Tank?

The exact cost of a water tank depends on things like where it’s being constructed, how big it is, what it’s expected to hold — and so on. But concrete and steel are going to have differing price ranges. Comparably, the two different types of tanks can be expected to last for similar amounts of time. However, a steel tank may cost less in the long term than a concrete tank. For that matter, a well-maintained steel storage tank may better serve the needs of a municipality, making it worth the investment even more.

What Kind Of Maintenance Does An Above Ground Water Storage Tank Require?

An above ground storage tank will need to be maintained over the years — it can simply be left neglected. Typically, concrete and steel storage tanks need the same kind of maintenance. This usually means regular repairs to stop leaks, as well as protective coatings on the interiors and exteriors of the tanks. Water proof sealant may also need to be added. With that being said, it’s crucial to have these tanks further inspected on a regular basis, to ensure that they can hold water that has reached potable water specifications, and maintain that level of cleanliness.
