From Regional Roots to National Platform: How Ardurra Is Reshaping Water Infrastructure

What does it take to grow a small regional engineering firm into a nationally recognized, private equity-backed water infrastructure platform — in just nine years? In this episode of Engineering Influence, Ernesto Aguilar, CEO of Ardurra, takes us behind the scenes of one of the most intentional growth stories in the AEC industry. Ernesto walks through Ardura's evolution from its early days as a focused regional practice to a multi-market firm operating across what he calls the "Big Smile" markets — a strategic geographic arc where population growth, aging infrastructure, and capital investment are converging to create enormous demand for water-focused engineering services. Ernesto speaks candidly about the discipline behind their selective M&A strategy — why they pass on deals that don't fit, what they look for in a cultural match, and how they structure integrations to make sure acquired firms don't lose what made them great in the first place. Central to that effort are employee councils, an internal mechanism Ardura uses to maintain connection, trust, and continuity as the firm scales. The conversation also pulls back the curtain on what it's actually like to work with a private equity partner. Ernesto challenges some of the industry's assumptions about PE-backed firms, explaining how the right capital partner can accelerate mission-driven work rather than undermine it — and what engineering leaders should understand before entering that kind of relationship. Beyond Ardura's own journey, Ernesto offers a broader perspective on the state of water infrastructure in America — the funding landscape, the urgency of reinvestment, and why the engineering profession must get better at communicating the value of its work. He makes a compelling case for advocacy and innovation as twin imperatives: that the firms and professionals who will define the next decade are those who not only deliver excellent technical work, but who actively shape the policy environment and public understanding around infrastructure investment. Whether you're a firm leader thinking about growth strategy, an engineer curious about the PE landscape, or simply someone who cares about the future of water systems in this country, this episode is packed with insight.
