How New Orleans Is Building Resilient Water Systems for the 21st Century

This episode of 21st Century Water features a dynamic conversation with Ghassan Korban, Executive Director of the Sewage & Water Board of New Orleans. Korban shares insights from his six-year tenure, focusing on the challenges and transformative solutions for New Orleans’ water infrastructure, a system vital to a city below sea level. The episode dives into the critical steps taken to modernize the city’s systems, sustain its population, and adapt to increasing environmental challenges.

Korban reflects on transitioning to New Orleans after 31 years in Milwaukee, driven by his passion for solving complex engineering problems. He recounts inheriting a system struggling with aging infrastructure and a battered reputation following significant flooding in 2017. Korban emphasizes the importance of prioritizing efforts, starting with stabilizing critical systems while pursuing long-term, future-proof solutions.

A major milestone for the city has been the development of a new power generation complex, ensuring reliable energy for drainage operations—essential for keeping the city dry during rain events. This new system transitions from antiquated, failure-prone turbines to a robust mix of external power supply and backup gas turbines, designed to serve the city for decades. Korban also highlights the successful rollout of smart meters (AMI), addressing billing inaccuracies and modernizing customer service, with over half the population now transitioned to the new system.

The discussion explores innovative funding strategies, including New Orleans’ unique “fair share” agreement, which channels tourism-generated tax revenue into water infrastructure projects. With the Super Bowl around the corner and Mardi Gras to follow, Korban explains New Orleans' unique position as a city with more tourists than residents. This effort, alongside loans and grants from programs like WIFIA and SRF, has helped fund critical improvements while reducing the financial burden on residents. Korban underscores the importance of earning trust through effective execution, ensuring future funding access.

Korban also describes the intricacies of New Orleans’ drainage system, consisting of 24 strategically placed pumping stations with nearly 100 pumps. These systems often activate up to 20 times a year, often during heavy rains, to prevent flooding. Additionally, Korban shares the city’s response to new threats like saltwater intrusion in the Mississippi River, driven by drought and climate change, which jeopardizes the city's raw water supply.

The episode concludes with a discussion on the importance of workforce development and legacy building. Korban expresses confidence in the team he has cultivated and their ability to carry forward a culture of innovation, responsibility, and resilience. He also emphasizes the urgency of addressing talent gaps and sustaining investment in infrastructure to meet the evolving demands of a changing environment.

Korban’s work exemplifies leadership through prioritization, execution, and adaptability. His focus on sustainable, resilient systems and creative funding solutions serves as a model for cities grappling with aging infrastructure and climate challenges.
