A Conversation With Peng:
Tell us about your career journey.
I began my career as a project engineer focused on the technical design of water and wastewater projects. Over time, I grew into a lead engineer and design manager, guiding projects from concept through construction. Along the way, I became curious about what happens after a project is built and how systems perform in real-world operations.
After 16 years in consulting, I transitioned to Veolia’s utility group to gain that perspective. There, I managed vertical (non-linear) projects across Pennsylvania, overseeing everything from planning and design to operations support and financial performance. When PFAS emerged as a critical industry issue, I stepped into the role of PFAS program manager, leading strategy and implementation across the MidAtlantic region. It was a rewarding experience that deepened my understanding of utility operations and strengthened many professional relationships.
After five years, I chose to return to consulting to refocus on technical design, bringing with me a broader, more integrated perspective.
What aspect of working in your field do you find most rewarding?
I’m driven by technical excellence and a commitment to getting the job done right. The most rewarding part of my work is seeing a design move from paper to reality and then watching the system perform as intended. That full lifecycle is where I find the greatest satisfaction.
What does your work look like and why is it important?
Right now, I’m working on several engaging projects, including designing a new solids handling system for a 7 million gallons per day wastewater treatment plant and evaluating the consolidation of multiple small facilities into a new regional plant. Opportunities like these are increasingly rare, as much of today’s work focuses on upgrades and rehabilitation.
My day-to-day work includes collaborating with teams, performing technical analyses, conducting research, and preparing reports. The pace is fast, and the work is meaningful. At its core, what we do protects public health and the environment. For me, environmental stewardship isn’t abstract; it’s a daily responsibility.
“Peng brings a unique perspective shaped by experience on both sides of the industry. That insight allows him to develop wastewater treatment solutions that are practical to build, efficient to operate, and deliver lasting value for our clients.”

Principal Project Manager, Water
How do you stay current with the industry?
I’ve been an active member of the Water Environment Federation and the American Water Works Association for many years, and I regularly attend state and local conferences and workshops to exchange ideas and stay informed about emerging trends. I also closely follow the U.S. Environmental Protection Agency and Pennsylvania Department of Environmental Protection regulations to ensure my work aligns with evolving standards.
What are some key lessons you’ve learned?
When designing a project, it’s important to think like both a contractor and an operator, asking “how will this be built, and how will it be run?” That perspective leads to more practical and effective solutions.
Equally important is attention to detail, which helps minimize changes during construction. At the same time, no project is perfect. Challenges are part of the process. The key is to learn from them and continuously improve.
What inspired you to join GFT, and what keeps you here?
The water and wastewater industry is a small, well-connected community. Before joining GFT, I had worked with several team members and knew others through the industry. I respected their expertise and appreciated their collaborative approach, so when I joined, I immediately felt at home.
Earlier in my career, I often saw the firm listed as the original designer on project drawings. That left a strong impression and sparked my curiosity.
Location also played a role. In a previous role, I had a long commute of about 80 miles each way. Now, I’m just five minutes from the office, which allows for a much better balance.
What keeps me here is the combination of strong teamwork and a deep knowledge base. People are willing to share expertise and support one another, which makes a real difference.
How do you unwind or recharge?
I’ve been fishing since I was five years old, and it remains one of my favorite ways to relax. Being outdoors helps me recharge, and it’s always enjoyable to connect with fellow anglers, sometimes even discovering a few “secret” spots.
A few years ago, my wife and I began hiking with friends throughout central Pennsylvania. One of our favorite destinations is Pole Steeple Trail in Pine Grove Furnace State Park, near the midpoint of the Appalachian Trail.
I also enjoy reading, particularly books on history, people, and the environment.
At home, we maintain a small garden with flowers and vegetables. Our favorite flower is the Queen of the Night, and we like to share young plants with others each year.
