Digital stormwater management puts valuable information in the cloud

Starting in early 2017, citizens curious about how Chicago’s bioswales and porous asphalt handled storms could log on and watch real-time data upload to their screens. Though the portal is no longer being updated, the test project it represented was a success. This May, the City Tech Collaborative, based at the UI LABS nonprofit research […]

Pacific Institute report summarizes challenges, successes of stormwater capture in California

As natural water sources dwindle, communities across California increasingly rely on imported water. Climate change soon could make water supplies even more scarce. While experts predict droughts in the region to become more common, rainfall also is expected to become heavier and more frequent. A report released by the Pacific Institute (Oakland, Calif.) in June […]

China embarks on massive stormwater projects to plan for future water risks

China is midway through its decades-long South—North Water Transfer Project, a massive system of aqueducts intended to convey 44.8 billion m3 (11.8 trillion gal) of fresh water each year from China’s rural, rainy south to its drier and more urbanized north. However, the country also is exploring far-reaching ways to use stormwater as the basis […]

PWD has designed a monitoring program to collect many types of environmental data including precipitation, sewer flow, and data on GSI performance.

Data analyses confirm GSI value in overflow control

Designed to reduce combined sewer overflow, green infrastructure in the city of Philadelphia, Pa., in the U.S., has been proven effective based on monitoring data analyses, according to Dwayne Myers and Andrew Baldridge of CDM Smith and Chris Bergerson, Taylor Heffernan, Varsha Raj, Stephen White, and Elizabeth Mannarino of the Philadelphia Water Department. Many water […]

Researchers use waste carbon fiber to strengthen permeable pavement

Researchers in the Department of Civil and Environmental Engineering at Washington State University have demonstrated that permeable pavement can be improved with the addition of recycled carbon fiber composite material. Associate research professor Karl Englund and Assistant professor Somayeh Nassiri supplemented permeable concrete mixes with composite scraps sourced from Boeing (Chicago) manufacturing facilities and found […]

WIFIA-financed King County, Wash., stormwater treatment project to protect water quality in the Duwamish River

Construction is underway in the Georgetown neighborhood of Seattle, Wash., on a combined sewer overflow (CSO) wet weather treatment station that will treat up to 265 million L/d (70 mgd) of polluted stormwater runoff that currently can flow into the Duwamish River during severe rain events. The $262 million Georgetown Wet Weather Treatment Station — […]

Roadway runoff causes long-term sensory damage in Pacific Northwest salmon

Toxic roadway pollutants captured and conveyed by stormwater pose a serious threat to coho salmon and other fish in the Pacific Northwest’s urban watersheds. New research from Washington State University (WSU; Vancouver) shows that green infrastructure can help reduce mortality rates, but that pollutants can still potentially make fish more susceptible to predators.   Salmon’s […]
