Modeling for Transition: Deploying rainwater harvesting systems in citywide water infrastructure systems

Qingshi Tu

Yale University,

Qingshi Tu researches with Julie Zimmerman’s group, specifically investigating development and implementation of sustainable technologies via life cycle assessment (LCA), techno-economic analysis (TEA) and computational modeling approaches (e.g. agent-based modeling). Completing his PhD in Environmental Engineering at the University of Cincinnati, Qingshi’s doctoral work focused on technology development and environmental impact assessment for producing biofuels and bioenergy from waste fats, oils and greases (FOG), exploring sustainable solutions to the long-standing issue of FOG management. Currently, Qingshi is evaluating environmental and economic implications of the algal biorefinery concept, where he creates life cycle inventory database for the emerging technologies such as hydrothermal liquefaction and supercritical fluid extraction/reaction systems. He also compares resource and energy recovery potential between centralized and decentralized wastewater treatment infrastructure systems, which covers conventional and emerging technologies including source separation and green infrastructure.


In modern cities, water flows are managed by centralized and mechanized infrastructures. Increasingly, this 20th-century water management paradigm is considered to be inadequate, vulnerable, inefficient and costly under both... [ view full abstract ]
