What is one challenge faced by Walmart in managing stormwater effectively?

Variability in stormwater quality and quantity from different geographical locations is a significant challenge for Walmart in managing stormwater effectively. Each location can experience different rainfall patterns, soil types, and land uses, leading to diverse stormwater characteristics. This variability necessitates customized stormwater management solutions that cater to the unique conditions of each site, making it more complex and resource-intensive.

For instance, a store located in an area with heavy rainfall may need a robust drainage system, while one in a drier region might focus on rainwater harvesting. Additionally, the presence of pollutants can vary, affecting the treatment processes used. Therefore, understanding and adapting to these differences is crucial for effective stormwater management, and it poses a challenge in ensuring compliance with environmental regulations and sustainability goals across all locations.
