About Us
TDH Services is a third-generation engineering and consulting firm with deep roots in the U.S. utilities sector, tracing our legacy back to the 1950s through Southern California Edison (SCE), fire protection systems, and municipal water districts. Our staff work regularly with the SWRCB, Public Utilities Commission, and State Energy Efficiency Programs since 2006. Built on decades of field-proven experience and technical leadership, TDH Services delivers trusted engineering solutions for critical water and energy infrastructure.
We are recognized industry leaders and subject-matter experts in water systems engineering, with specialized expertise in water well and pump design, hydraulic and system analysis, energy efficiency optimization, rehabilitation and renovation planning, and performance upgrades. Our work emphasizes lifecycle reliability, operational resilience, and compliance with evolving regulatory and sustainability requirements. TDH Services is particularly known for its advanced capabilities in rotating equipment diagnostics, including vibration analysis, performance benchmarking, root-cause failure investigation, and efficiency improvements for high-value pumping assets.
In addition to our engineering and water systems expertise, TDH Services brings over 25 years of experience in law enforcement, the U.S. justice system, and facilities and infrastructure risk management and security assessment. This rare, cross-disciplinary background allows us to approach water and energy assets through a Department of Homeland Security (DHS) Critical Infrastructure Protection (CIP) lens—integrating physical security, operational risk, system resilience, and threat mitigation into engineering decision-making.
By combining engineering excellence with security-informed risk assessment, TDH Services helps utilities and public agencies protect mission-critical infrastructure, enhance system reliability, reduce vulnerability, and ensure continuity of operations. Our approach aligns with DHS CISA guidance, best practices for critical infrastructure resilience, and the operational realities faced by municipal, regional, and special district agencies.
At TDH Services, engineering is more than design—it is infrastructure stewardship. We partner with public agencies to deliver resilient, efficient, and secure water systems that serve communities today while safeguarding resources for the future.
