Hi, I’m Christoph Lohr.
My work is shaped by years of experience, a commitment to public health, and a belief that plumbing systems should be designed with intention and clarity. I bring a systems-based approach to every project, connecting hydraulics, codes, research, and real-world behavior to create solutions that last.
My Approach
What began as a conglomeration of early interest has become a cohesive framework for rethinking how we design and manage water systems. I’m grateful for the progress so far and even more committed to what comes next. What sets my work apart isn’t just the tools, it’s the deliberate, systems-level intention behind them. I strive to understand context deeply, explore possibilities rigorously, and create purposeful solutions that endure.
Systems thinking
Each step reflects an understanding of how parts interact within the whole, allowing us to design solutions that are intentional, resilient, and enduring.
Strategic Foresight
Provide solutions that are intentional, resilient, and enduring by anticipating how systems will behave, evolve, and respond over time.
