A recent article in Environmental Health Perspectives, “Stormwater Strategies: Cities Prepare Aging Infrastructure for Climate Change,” discusses how utilities can adapt to more-intense wet weather events. Heavier rainfall is expected to increase sewer overflows and associated health risks. The article, by Rebecca Kessler, discusses what some cities are doing to prepare and highlights trends toward green infrastructure and other innovative approaches. Toronto, for example, is upgrading its storm sewers to handle larger flows, despite those pipelines being well within their useful lifespans. Also, check out Chapter 7.3 on stormwater management plans within Rethinking Our Water Ways, a guide to water and watershed planning in the face of climate change in British Columbia, Canada.
