About Us

KEH & Associates, Inc., (KEH) was formed in 2006 and has grown into a highly respected firm, providing engineering and consultancy services for the water, wastewater, and recycled water industry throughout Southern California. In 2018, KEH became a business group of global infrastructure firm Gannett Fleming, expanding our network of resources to more than 2,300 employees and 60 offices worldwide.


Backed by the strength of Gannett Fleming, KEH continues to provide client-focused planning, design, operations support, startup and testing services, program management, and construction management services to our municipal water infrastructure clients.


“Our current and future clients in California and the surrounding states can now benefit from Gannett Fleming’s full range of engineering, construction management, and program management services,” said Ken Hume, PE, former president of KEH and newly appointed West Region Water Business Line leader at Gannett Fleming. “We will continue to focus on client needs and the unwavering commitment to service excellence that is the foundation of both firms.”


Recognized for our acute understanding of water reclamation and reuse, we develop public sector programs that help ensure safe, clean, and reliable water supplies. We utilize technical innovations and apply proven experience to solve our clients’ challenges, and consistently deliver projects on schedule and within budget.
