With so many uses for water, both potable and non-potable, there need to be many ways to store it as well. Water storage has existed since the dawn of civilization itself and has continued to improve as sanitation procedures developed. Some water storage solutions—such as old cisterns—still exist to this day, hidden underneath metropolises and the daily humdrum of traffic.

Where underground cisterns once ruled, we now have mighty water tanks crafted from hardy materials we never thought possible. Learn about the different types of water tanks that we still use today and their uses to consider which best fits your needs.

Underground Water Tanks

Many water tanks work best underground, where they take up the least amount of space. If you live in a rural area without a sewer system, you’re likely familiar with septic tanks and underground water storage. These are forms of water tanks, though septic tanks typically handle wastewater.

Reservoirs and Cisterns

Reservoirs and cisterns designed for holding potable drinking water or rainwater are typically constructed from plastic, fiberglass, or concrete. These are different than naturally occurring reservoirs found in the Earth because they are man-made, and the user must install them. Cisterns are different than well water because they provide an area for water storage before usage, whereas well water draws directly from the aquifer. This means that water may undergo purification before entering a secure cistern or underground reservoir.

Septic Systems

Septic tanks, while related, typically only have one use—to capture and release wastewater to the leach field for purification. Some households may have a special system to separate, capture, and reuse gray water or wastewater without the contaminants from toilets.

Types of Above-Ground Water Tanks

When you need a water tank for heavy industry use, you may not have the ability to store water underground due to the location or local laws. If your water may contain contaminants, storing it above ground is essential. Some above-ground water storage solutions are:

Small Rainwater Storage Tanks for Household Use

Typically made of steel or plastic, above-ground rainwater storage tanks work just the same as underground tanks, though they require less work. Their installation and initial cost may be easier on a homeowner’s budget than an underground tank. After capturing rainwater, homeowners may use it around the outside of the home for lawn care.

Large Industrial Bolted Steel Water Tanks

For industries or cities that require a large amount of water, a bolted steel water tank is the answer. These tanks hold massive amounts of water for use in commercial, industrial, or municipal needs. In smaller cities and towns, these steel water tanks rise high above the nearby buildings with the name or logo of the location printed proudly on them.

Medium Water Tanks

If a business needs water storage but not enough to warrant a large steel tank, they may invest in a medium-sized fiberglass or polyethylene tank. These multipurpose tanks work well for contaminated water or even chemicals.

With all the different types of water tanks, it’s important to remember that the slightest corrosion or damage can cause costly consequences. Protect the interior of your household or industrial water tank with a PVC tank liner from Royal Liner, and it’ll last longer than its standard lifespan.
