Tips in How to Select the Best Liquid Containment Tanks

When you are talking about water storage containment, value for your money and quality will determine what materials or tank types you want to use when you are choosing water tank storage. Because of technology advancements when it comes to fabrication, design, engineering field construction techniques and coating process, some storage tanks used before have become outdated, while products that adjusted using modern technologies are pushed at the front of the line in field performance and product development.

When you are choosing the right water or wastewater storage containment starts with some considerations and questions. It is one of the biggest problems in liquid or water storage tank applications. Tank selection is sometimes based on preferred construction type instead of performance requirements. In checking different types of storage containment construction, you need to remember to start with the tank’s performance requirements in the field. It will lead you to define the tank type construction’s value attributes. Sometimes, a review of these valuable attributes or the value aspect that is set by the client as important, like low maintenance, the life expectancy of the tank, or the cost efficiency as well as the life cycle cost will guide you on how to choose the right container.

The list below will include the primary considerations that should be addressed by all liquid storage tank applications. If the reviewed application has no exceptional condition or is routine, a standard quotation should be requested from the manufacturers. If the items that are listed are a concern, a professional or specialist in storage tank application should tell people about how to correct the approach.

Application Considerations

Are the tanks using a unique storage process requirement like digester, agitation, or pressure?

What capacity requirements are they using? Gallons or Cubic meters?

What application codes or project design condition are they using?

What’s the temperature and the pH level of the stored liquid?

What materials are best used when making a storage tank?

What interface responsibility or type of configuration the manufacturers are using?

What is the tank’s cathodic protection requirements and corrosion allowance?

Are the tanks using concrete ring wall, base set, concrete slab, external saddles or steel bottom as a foundation?

Do they have warranty requirements or performance guarantee?

You don’t need to have all the answers to these questions, but you need to know how reliable your tank or containment specialist. If you can answer these questions, you can narrow down your selection process so that customers will have a basic understanding of water tank or containment.

Tank Styles

Generally, all water storage tanks that are required to have a volume of less than 90,000 gallons should use a Smoothwall welded bolt or shop-welded tanks. Both can be used interchangeably in industrial or commercial use. The bolted steel tanks and shop-welded tanks have its advantages. The tank’s installed costs like materials, field installation and freight costs are compared, to know which tanks suit your needs.

Bolted rolled, tapered panel, concrete, field-weld and hybrid tank construction are used in large volume water storage applications. All known designs are specified in the power industry. In most commercial and industrial applications, the bolted RTP and hybrid steel tanks are the cheapest or the most cost-efficient among all designs. Concrete and field-weld tasks require more complex installation timeframes, which means a higher installation cost.

Beyond the sales pitch from manufacturers and vendors, when it comes to value attributes compared to the cost of the installation and life expectancy of the tank, it is best to know some facts about ground storage reservoirs.

You need to specify if the water tank is below or above ground. The best container for above ground installation is concrete with aluminum dome cover.

You need to specify what kind of bolted tank is best for water storage tank. One of the best storage tanks available today is bolted RTP steel tank with concrete or steel bottom and aluminum dome cover.

Bolted RTP

Bolted RTP is used in most anaerobic digesters. Bolted, field-weld and shop-weld tanks are available in stainless steel or carbon coated steel materials. All storage tanks are customized depending on the client’s preference and are available at grade level or areas that are elevated. Tank accessories may include maintenance platform access, agitators, level nozzles for control, insulations, heaters, spiral stairways, caged ladder, customs requirements in case of system integration and perimeter quadrants.


If the basic requirements in tanks are covered, you can expect a long-lasting water containment tank that is free from defects and problems. In today’s industrial as well as commercial tank application, there are tanks all over the world that are 100 years old or older. It still depends on what materials you use and the maintenance you apply to the tank. It is always crucial that value and quality will be your priority when selecting your future water containment tanks.
