Rain barrels and other household stormwater strategies are working—for now

Phys · · 1186 words · By Britt Faulstick

Researchers from Drexel University have developed a model demonstrating that decentralized stormwater management strategies, such as rain barrels and water-efficient fixtures, can reduce sewer overflows and flooding by 11-13%. The study suggests these household-level efforts remain effective even under projected increases in sea level and precipitation intensity.
