In this Deep Dive, we are highlighting how Tom and his team enhanced the reliability of New York City’s sewer infrastructure by rehabilitating the Avenue U Pumping Station, while implementing innovative strategies to ensure uninterrupted operations during the upgrade.

In urban environments, rehabilitating critical infrastructure like pumping stations presents a unique set of challenges, especially when continuous operation is non-negotiable. The Avenue U Pumping Station rehabilitation project in Brooklyn, New York City (NYC), exemplifies innovative engineering solutions to these challenges. The pumping station serves the community by collecting and pumping wastewater from the surrounding area to the treatment facility, preventing flooding and ensuring the safe and reliable conveyance of sewage. It plays a critical role in protecting public health and maintaining environmental standards in Brooklyn.

Serving the community for decades, the station faced aging equipment, structural vulnerabilities and limited operational flexibility. The challenge, therefore, was to modernize the station while keeping it fully operational throughout the construction process. The project is not only addressing immediate infrastructure needs but also serves as a model for future rehabilitation efforts. As cities worldwide grapple with aging infrastructure, the lessons from Avenue U will guide engineers and policymakers in maintaining essential services during complex upgrades.

The Avenue U Pumping Station is certainly one of the most impactful projects I’ve delivered. As the design manager for this project, I led a multidisciplinary team to address the complex challenges of upgrading this critical piece of infrastructure while ensuring uninterrupted operations. The Avenue U Pumping Station is a cornerstone of the city’s wastewater management system, and its rehabilitation is essential to ensure the long-term reliability and resilience of this vital infrastructure.

With the design phase now complete and the project moving into the bid phase, we are one step closer to realizing the tangible outcomes of this work. The upgrades will improve the operational efficiency of the pumping station, reducing the risk of system failures and extending its service life by decades. This will directly contribute to environmental sustainability by preventing potential wastewater overflows, which can have severe ecological and public health impacts. Notably, this project is pursuing at least Gold Envision Certification, underscoring its commitment to sustainability and resilience. Economically, the project will ensure uninterrupted wastewater services for thousands of residents and businesses, avoiding costly disruptions and maintaining the quality of life in the community.

By implementing innovative solutions to maintain continuous operations during construction, we are minimizing the project’s environmental footprint and ensuring positive social impacts by safeguarding essential services for the community.

What was a key challenge you/your team faced while working on this project? How did you solve it?

The primary challenge was designing a rehabilitation plan for the pumping station that would allow it to remain fully operational throughout the construction process. This required developing a comprehensive bypass pumping system capable of handling the station’s full capacity without interrupting service. The complexity of working in a dense urban environment, with limited space and strict regulatory requirements, added another layer of difficulty.

As the design manager, I played a central role in coordinating with the client, contractors, and other stakeholders to develop an innovative bypass system that is both constructible and resilient. My responsibilities included managing the design team, ensuring seamless communication across disciplines, and aligning our approach with the client’s goals and regulatory requirements. We conducted detailed hydraulic modeling and risk assessments to ensure the system could handle peak flows and unexpected scenarios. One key innovation was incorporating an interconnecting pipe between two influent manholes at the pumping station, replicating existing conditions and enhancing system flexibility.

A memorable breakthrough moment came when we finalized the design of the bypass system, ensuring it met all operational and regulatory requirements. This was a testament to the team’s meticulous planning, collaboration and leadership. My role involved not only bringing unique ideas to the table, such as optimizing the layout of the bypass system to minimize space requirements but also ensuring that these ideas were executed effectively through close coordination with all parties involved.

Cynthia Hartley’s background includes nearly two decades in the international development sector. Since joining ArchTam in 2016, she has focused on projects ranging from economic growth, urban resilience and environment to disaster risk management, from both the business development and project implementation sides. Cynthia works closely with our clients to pinpoint challenges and engineer solutions aimed at bolstering their effectiveness in mitigating disaster losses. She also provides technical assistance for infrastructure grant applications. Her love for meeting and engaging with people from diverse cultures and backgrounds to strengthen communities inspires her work.

Tell us about what inspired you to join the industry.

I’ve always been an advocate for safeguarding our environment and fostering community growth. In graduate school, I wrote my thesis on the expansion of an environmental engineering firm (MWH, now Stantec) into developing countries. The next year, I entered the Architecture and Engineering (A/E) industry working for the very same company. Several years later, I experienced firsthand the impact that natural hazards, in particular, Superstorm Sandy, can have on communities. This led me to advance my commitment and work in environmental protection, disaster risk management, and resilience, specifically in the A/E industry. In a lot of ways, it’s a continuation of the international development work I did previously. My work in our industry aligns with my desire to have a broader impact on society and leave a legacy.

What is your favorite ArchTam project that you’ve worked on and why?

A common theme that runs through all my favorite projects is strategic planning and problem solving. I recently worked with West Virginia’s State Resiliency Office to develop a forward-thinking strategic plan for the state. This involved understanding West Virginia’s historical successes, aggregating its diverse challenges and needs, identifying its strengths, and filling in the gaps to meet the objectives of a legislative mandate for a statewide resiliency plan. We worked with stakeholders who care deeply about resilience and disaster risk reduction to update the state’s flood strategy for the first time in 20 years. The two-year Flood Resiliency Plan we helped develop identifies the actions needed to achieve the greatest impact for flood resiliency in West Virginia.

One of the next steps will be to develop an education and outreach strategy to identify ways to reach all people, including local and marginalized communities. In international development terms, reaching the last mile includes reaching people at the lowest economic rungs of society, people with disabilities, and the aging population — people who do not have (or have limited) access to the internet or the information it provides. We also need to reach private sector businesses that employ people from West Virginia’s communities and depend on them to generate revenue. If you’re a dairy provider in West Virginia and the roads are closed or lives are at risk due to flooding, people will not be able to access or afford your products and your employees will not be able to show up for work. By reaching the private sector and communities, we can make this a “whole-of-society” approach, because everyone has a stake in this. We’re also starting to work with the State Resiliency Office to develop a grants management program and a grants management training manual to help raise the funds needed for outreach and education and implementation of the flood resiliency plan.

Tell us a story of how your work positively impacted the community.

At ArchTam, I’ve been able to reach across geographies and engage with my colleagues throughout the world — from offices in South Africa, Romania, Australia, Spain, and elsewhere — to share knowledge and exchange lessons learned, improving upon what we know to benefit the global community. And that’s how I find the greatest fulfillment — by collaborating with diverse people and groups to help the whole of society.

A key focus of my work at ArchTam has been helping countries, states, and cities develop strategies to build resiliency. This has included initiatives with Federal Emergency Management Agency (FEMA), U.S. Agency for International Development, UN’s Private Sector Alliance for Disaster Resilient Reduction (UNDRR), and ARISE-US, the U.S. chapter of the UNDRR. ArchTam was one of the founding members of ARISE-US and through that engagement we developed the Disaster Resilience Scorecard for Cities. I helped UNDRR review the Government of Bulgaria’s first disaster risk reduction strategy, and as part of FEMA’s Hazard Mitigation Assistance program, I worked closely with FEMA headquarters, leading a root cause analysis of its grants administration process to reduce the time it takes to obligate funding to the communities that need it the most. In all these initiatives, I’ve engaged with a wide range of people from diverse backgrounds to help communities overcome adversities and become more resilient.
