Foreword

An increasing number of wastewater structures, systems, and components are experiencing extreme corrosion and deterioration. Hydrogen sulfide (H2S) corrosion and microbiologically influenced corrosion (MIC) are principal contributors to the problems.

The purpose of the report is to increase awareness of the problem of corrosion, and to provide a high-level overview of the current state-of-the-practice and current state-of-the-art renewal technologies for rehabilitation, repair, and replacement of existing systems, structures, and components in wastewater systems.

This report is intended for use by design engineers, decision makers, and other stakeholders in municipalities who are involved with the management, design, construction, maintenance, and/or operation of potable, sewer, and storm water systems, components, and structures.
