How do I know what size water tank I will need?

The size of the water tank required to meet your capacity needs will vary widely by the application and the period of time for which the water will be stored.

In a commercial or industrial building, for example, capacity requirements will be determined by a combination of federal, state, and local safety regulations, the equipment installed in the building and the determination of the fire protection engineer. The water storage tank must hold a large enough volume of water to operate the sprinkler system, hoses and other fire equipment in an emergency.

For a municipal water system, the required capacity will be determined by the number of households that must be furnished with potable water, and how much capacity must be kept in reserve to keep the system functioning properly. According to the EPA, the average household in the United States uses 400 gallons of water a day.

For a private well system, capacity will be determined by the mount of water used daily, and the desired amount of storage. For example, in a private home, if the homeowner wants a full week of water storage for emergencies, about a 3,000 gallon tank would be required.

What materials can I choose from?

At Gulf Coast Tank & Construction, we offer water tanks manufactured with one of four different materials:

  • Powder-Coated Carbon Steel
  • Galvanized Carbon Steel
  • Stainless Steel
  • Fiberglass Reinforced Plastic (FRP)

Depending on the application, standard galvanized or stainless steel hardware are used, with optional poly-capped or fully encapsulated coatings to resist corrosion or chemical reactions, in addition to either a EPDM rubber, Buna-N or Viton gasket.

The choice of materials will vary greatly on the contents of the storage tank. A water tank for potable water must meet strict USDA, EPA and NSF Standard 61 standards, and may require stainless steel or FRP construction. Clean, non-potable water for agricultural or industrial use can be stored in any of the standard materials, but contaminated water may require special gaskets and hardware to minimize leaks caused by corrosion, chemical reactions and other processes.

How long does installation take?

Installation times vary by the size of the tank, the applications and the specific requirements of the installation site. Larger tanks will take longer to install than smaller ones, and if the installation is complex or space is limited, the process may take longer. Compared to other types of tanks, however, the installation process is significantly faster, allowing normal building operations to resume in a far shorter period of time.

Bolted water tanks in optimal conditions require only a third of the time that it takes to install a similar concrete or welded tank. Because the sections of the bolted tank are manufactured and finished in a controlled manufacturing environment, construction is not prone to weather delays and there is no need to apply the finish coat onsite, which reduces labor costs. The modular design of bolted water tanks also allows for easy expansion in the future if your storage requirements increase, along with easy repairs, should a section or an accessory fail to perform as expected.

What are the most important features of bolted water tanks?

    Bolted water tanks offer many features that make them a better choice than competing designs, including:

    • Precision manufacturing and finishing that is performed in a controlled environment
    • Long-lasting finish options that resist corrosion, including stainless, galvanized and powder-coated surfaces
    • Top-of-the-line materials, including carbon, stainless and galvanized steel
    • Fast installation, with large sections that are fitted with gaskets and bolted together
    • Easy to repair, with sections that can easily be unbolted and replaced
    • Custom manufacturing for a specific application, such as corrosion-resistant tanks for wastewater
    • High quality control standards

    Bolted water tanks are a quick and easy way to add durable, long-lasting water storage for any type of application—industrial, commercial, residential, municipal or rural.

    4 Great Applications for an Underground Water Tank:

    Water tanks aren’t just for massive farming purposes. There are a variety of businesses and private individuals who might benefit from an underground water storage tank. Just consider these four great water tank applications:


    1. Greywater.  Greywater refers to water that has been exposed to minor contaminants often can be harvested and re-used for non-drinking purposes, such as for irrigation and general cleaning. An underground water tank can be outfitted to catch and store greywater from sources like roof runoff and waste water from sinks and showers.
    2. Fire Cisterns.  Many regions in the country experience dry, hot seasons ideal for wildfires. Underground tanks are ideal for storing the water necessary to help keep these fires in check and prevent any property damages.
    3. Agri-business.  Farms and ranches with high water needs need to have reliable access to water no matter what season it is. An underground water tank installation ensures that all of your irrigation and livestock watering needs are met.
    4. Rainwater Harvesting.   Opposite wildfire conditions, heavy rains can cause their own significant issues like erosion and flooding damage. Water tanks can be used to divert excess rainwater runoff to prevent such damages, with the added benefit of having collected greywater to reuse.

    Steel Water Tanks 101

    Most steel water tanks are constructed out of galvanized steel that has been treated with a special zinc coating to fight corrosion. A steel water tank can be built to hold as small or as large of a capacity as you might need, including extra large units capable of holding millions of gallons of water.

    However, even the highest quality galvanized steel tanks can rust and corrode over time. That’s why the best steel tanks come with liners made of food-grade polyethylene. Or, opt for stainless steel tanks that have a longer, corrosion-free lifespan.
