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 […]

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 […]
