Shreveport wins 2026 Concrete Decision Award for sewer overflow project

The City of Shreveport, Louisiana, won Preload’s 2026 Concrete Decision Award for its Dilg League Drive sanitary sewer overflow mitigation project. The recognition highlights a wastewater infrastructure build completed in March 2025 after weather delays and includes a link to more information from Preload.

Why it matters: - Shreveport’s win puts a spotlight on wastewater infrastructure projects that help cities reduce sanitary sewer overflows and improve long-term reliability. - The award also recognizes the kind of public-private coordination needed to deliver complex concrete storage and treatment assets.

What happened: - Preload named the City of Shreveport, Louisiana, the winner of the 2026 Concrete Decision Award. - The winning project was the Dilg League Drive Sanitary Sewer Overflow Mitigation project. - Work on the type 3 tank began in late November 2024. - The project was completed in March 2025. - The work faced weather delays and Louisiana’s muddy rain season during construction.

The details: - Civil Design Group LLC served as the lead design engineer for Shreveport’s first above-ground wastewater storage facility. - Mitch Guy, P.E., said the firm was honored to serve in that role and looked forward to future opportunities to improve Shreveport’s infrastructure through innovative solutions. - Preload said its more than 90 years of experience in prestressed concrete tank design and construction supported the project. - The project included an in-house installed four-nozzle wash down system. - The wash down system sprays water inside the tank to clean debris collected over time. - Past Concrete Decision Award winners include Hutto, Texas, in 2025; Eden Prairie, Minnesota, in 2022; Sellersburg, Indiana, in 2019; and Lubbock, Texas, in 2017. - More information is available in Preload’s announcement.

Between the lines: - The award appears to be as much about execution under difficult field conditions as it is about the final structure. - Preload framed the win as evidence that infrastructure investment and strong partnerships can produce durable, sustainable systems. - The emphasis on precision engineering and an integrated wash down system suggests the project was designed for easier maintenance over time.

What's next: - Preload is directing readers to its website for additional details on the project and previous award winners. - The recognition may help position Shreveport’s project as a reference point for other cities evaluating sewer overflow mitigation and above-ground storage solutions.

The bottom line: - Shreveport’s award underscores how utility projects can gain national attention when they combine technical complexity, resilience and public value.
