About the Author — Heidi Lee

Heidi Lee is a municipal infrastructure specialist with over 15 years of experience in wastewater systems, underground utility rehabilitation, and trenchless technology. She has worked alongside public works departments across the United States, advising on manhole condition assessment, polyurea coating selection, and long-term asset management programs.

Heidi holds certifications in NASSCO pipeline assessment and has consulted on manhole rehabilitation projects ranging from mid-size municipalities to large metropolitan sewer districts. Her work spans the full lifecycle of infrastructure recovery — from initial CCTV inspection and PACP condition rating through surface preparation, lining application, and post-application quality assurance.

Our Mission

Manholes are among the most critical — and most overlooked — components of any city’s wastewater infrastructure. When they fail, the consequences range from costly emergency repairs to environmental contamination and public safety hazards. Our mission is to provide clear, technically accurate, and actionable information that helps decision-makers protect their infrastructure before problems become crises.

We cover the full range of manhole recovery topics: polyurea and epoxy lining systems, injection grouting, structural rehabilitation standards, NASSCO and PACP guidelines, cost-benefit analysis for rehabilitation vs. replacement, and the growing trend of municipalities taking rehabilitation in-house with their own spray rig programs.
