SAWS Utilizes Prestressed Concrete Storage Tank for Durable Solution

Over 70 years ago, Preload pioneered a novel method of applying high-strength wire to a circular concrete storage tank to create a durable, economical and low-maintenance solution for liquid storage. The company’s development, known as “wire-winding,” not only created an industry but also the most widely utilized storage tank structure in use today.

Today, the design and construction methods invented by Preload are used to construct some of the largest tank structures in the world for water storage, wastewater and many industrial applications. Preload’s recent project at the Old Pearsall Road Pump Station for the San Antonio Water System (SAWS) in San Antonio, Texas, is an example of such a tank structure.

The ground storage reservoir has a total capacity of 7,500,000 gallons with room on site for an additional 7,500,000-gallon tank to be built in the future. SAWS chose an AWWA D110, Type III prestressed concrete tank for the project after researching various types of tank structures.

The choice to build a Preload prestressed concrete storage tank for this project represents the utility’s awareness that this tank type provides the best in long-term durability, coupled with low cost of ownership, and represents a tremendous savings in maintenance costs over the life of the structure when compared to that of other tanks.
