Stormwater management at landfills is changing as owners/operators are adapting their operating plans and designs to minimize the risks that come with heavier rainfall, and severe storm conditions. Landfill engineers are “overdesigning,” in regions hard hit in recent years by severe weather, and not designing for what is labeled as a statistically probable 25-year-storm.
Operations and maintenance are also preparing for changing conditions. William Mojica, Republic Services Director of Environmental Compliance is quoted in this article saying “It’s understanding the facility’s lifecycle, what best management practices (BMPs) are required and anticipating what may come.”
Jonathan Meronek, of SCS Engineers, notes similar strategies are being explored or employed along the U.S. coastlines including designing retention facilities to handle much larger storms.
