Our Fiberglass Water Tanks

AWWA D120, NFPA 22, NSF 61

Nationwide Tanks is proud to contribute to the efforts of water conservation by producing tanks that are maintenance and corrosion-free. Fiberglass tanks are lightweight, therefore easily transported to the customer’s location, and designed for efficient and quick installation. Ensuring a low-cost, long-life solution, we provide the industry with exceptional quality fiberglass tanks and dedicated customer service.

Nationwide’s underground fiberglass water tanks are designed specifically to meet the industry served. We will build our underground fiberglass tanks to meet AWWA D120, NFPA 22, and NSF 61 standards depending on project requirements for water and wastewater tanks. We analyze the project data the customer provides regarding the type of water, any chemical concentration present, and operational temperature. Then our resin chemists and engineering team review required design parameters, specified standards, site, and environmental concerns, to determine the correct resin and optimal tank design for each project. Nationwide Tanks’ technology team of engineers, chemists, and designers utilize the latest technology to produce a superior product. Our corrosion-resistant fiberglass tanks are durable, lightweight, and watertight, resulting in a longer life cycle than underground concrete or steel tanks.

Fire Protection Tanks

The versatility of fiberglass tanks makes them ideal for commercial fire protection applications. As concerns continue to grow about water shortages in many parts of the United States, municipalities and facility owners continue to search for ways to better manage their water resources. Water storage for fire protection systems is one specific application where plumbing, mechanical and fire protection engineers across the country are searching for reliable, cost-effective storage options to hold thousands of gallons of water. Whether used for dry hydrant, storage, or capture, specifying engineers prefer our underground fiberglass water tanks as they provide a reliable water source without obstructing the view or site layout as well as protect property values. All our fire protection tanks are manufactured to meet or exceed the material and design requirements in NFPA 22, NFPA 20, and NFPA 1142.
