Behind this simple organization chart lies an endless web of connections, influences, and negotiations that shape every water infrastructure project.

Understanding these dynamics is crucial, especially if you’re part of the EPC team or a water technology provider involved in design, procurement, or operations.

In this essay, I’ll guide you through the hidden roles, strategic interactions, and decision-making levers that determine how projects succeed, risks are managed, and opportunities are seized.

What you’ll learn in this essay:

  • The Owner Engineer Role: Discover how these key professionals validate designs, ensure compliance, maintain a holistic perspective, and protect the client’s interests in large water infrastructure projects.

  • Why External Validation Matters: Understand why investors, banks, and clients require independent oversight to mitigate risks and secure project success.

  • The Economics of Engineering Oversight: Learn who pays the Owner Engineer, why it’s strategic, and how upfront investment can lead to long-term OPEX savings.

  • Influencing Vendor Selection: See how specifiers and engineers impact procurement decisions, balancing innovation, risk, and supplier credibility.

  • The “CockFights”: Explore the intense negotiations in meetings where EPCs, owners, and engineers defend their interests, and how this shapes project outcomes.

  • EPC Pressure Dynamics: Gain insight into the weekly challenges EPC teams face, and how preparation and knowledge turn pressure into opportunity.

  • AI in Project Oversight: Discover how artificial intelligence is transforming meeting documentation, reducing bias, and creating transparent, reliable records.

  • Engineers as Strategic Guardians: Learn how those firms act as oversight mechanisms, bridging technical execution and client governance.
