Speakers
Adam Erispaha
EmNetMr. Erispaha is licensed civil engineer with a passion for building tools, increasing efficiency, and finding innovative solutions to complex problems. He works as a civil engineer and data scientist at the smart sewer technology firm, EmNet, where he develops hydraulic models and software to optimize urban sewer systems. In the past, Mr. Erispaha worked as an on-site consultant to the Philadelphia Water Department’s Planning and Research division where he provided technical and strategic planning support on large scale flood mitigation studies. His professional interests include modeling urban stormwater and flood mitigation systems, strategic infrastructure planning, climate change adaptation, policy development, and software development.
Scott Jeffers, PE, PhD
Water Resource EngineerDr. Scott Jeffers’s career focuses on urban water resources and green infrastructure collaborating with major municipalities internationally to address modern challenges in water, wastewater, and stormwater systems. Dr. Jeffers brings over 12 years’ experience in the water resource industry specializing in site and regional hydraulic/hydrologic modeling, permitting, capital improvement master planning, optimization/prioritization for asset management, IoT deployment, and a background in novel digital water techniques. Dr. Jeffers is a leading expert in EPA SWMM modeling and teaches hydrology and urban ecohydraulics at Drexel University. Recreationally, he is a musician and rock climber.
Stephen Maakestad
Mr. Maakestad is an associate engineer at Mott MacDonald who gained most of his project management experience with the Philadelphia Water Department’s Flood Relief Program and Long Term Combined Sewer Overflow (CSO) Control Program. As part of these programs, he managed the development of drawings, schedules, specifications, and cost estimates for large combined sewer reconstruction projects and stormwater management practices of various types. Mr. Maakestad has designed extensive water main relay, storm sewer, and sanitary sewer replacement projects. He has prepared contract drawings for large-scale and small-scale best management practices (BMPs), and he has performed hydraulic modeling of control structures. He has also gained experience in sustainable building design and construction while working as a consultant and commissioning agent for LEED-certified and energy efficient commercial buildings, including pharmaceutical/healthcare facilities.
