What is one practice that Walmart employs to reduce stormwater runoff from its facilities?

Implementing rain gardens and bioswales is a practice that effectively mitigates stormwater runoff from Walmart facilities. Rain gardens are designed to absorb rainwater from impervious surfaces, such as roofs and parking lots, allowing it to infiltrate into the ground rather than flow into storm drains. Bioswales are landscaped components designed to convey, filter, and manage stormwater. Both of these solutions enhance water quality by filtering pollutants and reduce the volume of runoff, thus lessening the risk of flooding and erosion.

This practice aligns with sustainable approaches to manage stormwater and contributes to a more environmentally friendly operation. Utilizing natural systems not only helps in managing water but also supports biodiversity and enhances the aesthetic value of the property.
