Small Water Tanks

Our small water tanks are compact, durable, and designed for suburban living.

Not every property needs a massive storage system. Sometimes, a smaller water tank is the perfect fit. Whether you’re collecting rainwater for your garden, storing emergency supply, or adding capacity to an existing system, Lakota Tank Company offers premium small tank options that blend quality, durability, and smart design.

We proudly offer two of the best compact tanks on the market: Thin Tanks and Texas Metal Tanks.

FAQs

What qualifies as a “small water tank”?

At Lakota Tank Company, we consider any tank under 5,000 gallons to be a small tank. Our most popular compact options range from 130 to 500 gallons for Texas Metal Tanks and 300 gallons for Thin Tanks.

What’s the best small tank for tight spaces?

The Thin Tank is ideal for narrow or limited spaces. At only 11.25 inches wide, it fits neatly along fences, walls, or garages—perfect for small lots, patios, or urban homes.

Are these tanks safe for drinking water?

Yes. Both Thin Tanks and Texas Metal Tanks are food-grade and potable-water safe. Thin Tanks use BPA-free, FDA-compliant resin, and Texas Metal Tanks are built with NSF-approved liners for safe drinking water storage.

Can multiple Thin Tanks be connected together?

Absolutely. Thin Tanks are designed for modular expansion — you can connect several units in series to increase capacity or create a functional privacy wall that stores water.

Do metal tanks rust or corrode over time?

Texas Metal Tanks are made from galvanized or stainless steel and lined with food-grade polymer coatings to prevent rust and corrosion, even in outdoor environments. With regular maintenance, they last for decades.

Do small tanks require maintenance?

Maintenance is minimal. We recommend checking inlets, outlets, and filters seasonally and rinsing the inside every 1–2 years to remove sediment. Our service team offers annual maintenance plans for convenience.
