Municipal Engineering

Performance You Can Count On—Because We Do the Work.

You are here:

Municipal engineering is about stewardship—delivering infrastructure that serves the community reliably while respecting public funds. 

From rehabilitating aging pipelines to commissioning state-of-the-art treatment facilities, we help municipalities navigate the technical, financial, and regulatory challenges of modern infrastructure management.

How We Deliver Value

The biggest challenges facing municipalities today are aging assets and tightening budgets. We deliver value by focusing on constructability and cost certainty.

We treat public dollars with the same rigor we apply to our own bottom line, ensuring that projects like the Fresno Southeast Surface Water Treatment Facility deliver maximum value to the ratepayer.

Water & Wastewater Infrastructure

Safe water and reliable sanitation are the core of public health. We specialize in the upgrade and expansion of municipal treatment systems. For the City of Paso Robles, we managed the modernization of their Wastewater Treatment Plant while keeping the facility fully operational for the community.

Regulatory Compliance Strategies

We provide the rapid engineering response needed to meet these mandates. When the City of Bakersfield faced new regulations for 1,2,3-Trichloropropane (TCP), we executed a fast-track mitigation program across 34 well sites. We help cities assess compliance gaps, design effective treatment solutions, and secure the necessary permits to satisfy regulators.

Capital Improvement Program (CIP) Support

We assist municipalities in prioritizing projects based on risk and return. 

By validating budgets with real-world construction data, we help cities avoid the “funding gap” where project costs outstrip approved bonds or grants.

Alternative Delivery for Public Works

We are leaders in alternative delivery methods like Design-Build and CMAR (Construction Management at Risk) for public agencies. 

The Visalia Water Conservation Plant utilized our expertise to deliver upgrades efficiently through a collaborative approach.

A Partner to Public Agencies

W. M. Lyles Co. has spent decades partnering with California’s cities and utility districts. We understand the unique pressures of municipal governance—from City Council approvals to ratepayer transparency.
