As part of its climate strategy to reach a fully renewable electricity grid by 2040, New York City is turning to offshore wind energy. However, the development of offshore wind structures present environmental and community challenges, including construction noise, air pollution, and marine disruption. As a Fall 2024 Innovation Challenge, the Junior Academy offered its New York City based students the opportunity to tackle these problems by designing solutions to remediate the impacts of offshore wind development, focusing on land and water preparation.
This team, composed of six high school students from New York, won the Junior Academy challenge on Remediation in South Brooklyn with a project to upgrade the hydraulic systems in the South Brooklyn port area. The students considered that, as the South Brooklyn Marine Terminal undergoes reconstruction, effective stormwater management will be crucial to manage stormwater and prevent flooding, block debris and pollutants from reaching the water, and protect the surrounding environment.
Current Issues that Impact South Brooklyn’s Water Systems
Team members had lengthy discussions while selecting the problem they wanted to tackle and developing their solution. “Respect and inclusivity were a big part of our success. We found that discussing our differences and voting on decisions helped keep things fair and balanced,” explains Ayten, one of the team members. “This project also changed the way I approach challenges. It taught me to think like an engineer focusing on finding solutions instead of getting discouraged by obstacles.” The team explored the hypothesis that integrating a scaled-up version of advanced filtration technologies into the existing sewer infrastructure would significantly enhance the hydraulic system’s effectiveness.
“Through my research I have learned more about hydraulic systems and the current issues that impact South Brooklyn’s water systems. Hydraulic separators are a type of stormwater management system used to ensure fresh water enters bodies of water without pollutants, similar to the function of water filters,” explains teammate Cindy. “Brooklyn’s hydraulic systems are in need of an upgrade to ensure that the port can have a fully functional vessel transportation system. For this the waters must be clear of debris.”
Designing a Filtration System
Their project focused on designing a filtration system prototype on CAD Fusion 360 (Computer-Aided Design) and then using Computational Fluid Dynamics (CFD) to test the prototype. “This project has strengthened my belief in teamwork and the importance of improving New York City’s old infrastructure,” explains team member Ankea. “One of my favorite aspects of this project was the opportunity to improve my CAD skills. I already had basic knowledge of CAD software like Onshape and Fusion but this project allowed me to learn more about CAD, especially computational fluid dynamics, from my peers and I was able to apply these new skills to my personal projects.”
The students developed a dual hydraulic separator system, consisting of two connected units, to address the specific filtration challenges posed by the unpredictable weather conditions typical of New York City. The primary separator operates under normal conditions and provides basic filtration, while the secondary separator is larger and designed to handle heavy runoff water during storm events. A sensor-controlled gate between the two detects water flow and automatically opens when high pressure is detected. In emergencies, the gate can also be operated manually.
The team equipped the two separators with advanced filtration systems to remove sediments, oil, debris and other pollutants before they enter the water. When they tested their solution, the team discovered that a filtration system with multiple small holes was more efficient than one with a single large hole. Not only was it able to filter out more debris but it also allowed for a faster flow of water, which is crucial during extreme weather events. Their aim was also to improve efficiency and reduce the need for frequent system maintenance, therefore optimizing performance while also cutting costs.
Breaking Down Complex Problems
“One significant takeaway from this experience is that solving complicated problems requires dissecting them into more manageable, connected tasks,” explains Bronx-resident Ohee. “Even though we focused on hydraulic system optimization, our work was part of a larger plan to restore the port as a hub for trade and transit. A solution that strikes a balance between environmental and human interests was shaped in large part by important variables including marine habitats, the demands of the local people, and the system’s sustainability.”
During the intense period they spent working together, the team members acquired new skills and a better understanding of teamwork. They also developed a new perspective on urban challenges. Among the major insights team member Annika gained through this challenge was “the broader implications of water treatment systems like hydraulic separators. These technologies extend beyond simply cleaning water—they prevent chemical runoff, safeguard marine ecosystems, and contribute to sustainable urban development,” she said. “Addressing New York City’s history of environmental challenges with innovative solutions is vital for both the city’s residents and its ecological future.”
Team lead Cameron felt that collaborating with the other participants on this challenge would help him in the future. “Working with my team over the last few months has allowed me to look at things from a new, more creative angle,” he said. “Being able to work on this project has been such a unique experience. I feel better prepared for when I start doing real research.”
