Siva Rama Satyam Bandaru, PhD

PhD ’20, University of California, Berkeley, Civil and Environmental Engineering

I’m interested in the development and implementation of Electro Chemical Arsenic Remediation (ECAR), a low cost robust technology to address groundwater arsenic contamination in rural South Asia and California. My current research focuses on  understanding the behavior of iron plates (electrodes) during long term electrocoagulation processes and developing alternate techniques to further increase the lifetime of iron electrodes.

    Dr. Adam Rausch

    Research and Design Engineer, University of California, Berkeley

    Worldwide, more than a billion people lack adequate access to clean drinking water. Certainly, solving such problems often requires new technology, as minimal infrastructure and financial limitations can effectively exclude existing solutions. When necessary, however, new technology is often not sufficient to provide sustained relief. Indeed, even mature technologies frequently fail in remote and developing-world settings. Therefore, it is crucial that we come to understand both technical and non-technical factors for such efforts. My current research includes improving capacitive deionization, targeting treatment of high-TDS water common in underground sources, as well as analyzing comparative case studies on the sustainability of rural infrastructure projects.

    Ph.D., Civil and Environmental Engineering (joint with Sally Thompson and Slav Hermanovicz)

    I am interested in integrating micro hydropower turbines in piped water supply  systems in the hills and mountains of developing countries. Recovering the otherwise dissipated energy of pressurized water would allow the decentralized generation of electricity within the communities. Under favorable conditions, such a multi-use approach increases the ability to generate income from infrastructure, which increases its financial sustainability. Using GIS, I am developing tools to assess the technical and economic feasibility of the concept at a large scale through spatial analyses and the development of hydrologic, economic and cost assessment models. Although my work is currently centered on Nepal, using global and freely available remote sensing data and open source software will hopefully allow these tools to be used globally to inform rural water infrastructure policy
