This book is a unique resource for professionals seeking a comprehensive understanding of microbiologically influenced corrosion in concrete sewers (MICC), which play a critical role in modern urban infrastructure. Corrosion can lead to structural collapse and significant financial losses due to the costly rehabilitation and replacement of damaged sewer systems. In the United States alone, sewer asset losses attributed to corrosion are estimated to reach $14 billion annually. The book provides a cross-disciplinary approach to understanding the physical, chemical, and biological processes that contribute to microbiologically influenced concrete corrosion. Readers will learn about corrosion rate measurement and characterization methods, controlling environmental factors, corrosion prediction models, and mitigation and control strategies. The book also covers the development of corrosion-resistant concrete. Written for civil engineers, environmental engineers, concrete technologists, and sewer operators and managers, this book is both informative and practical. It not only provides fundamental knowledge of the development of corrosion but also offers practical solutions that are economically and environmentally sustainable. By collating a range of corrosion analytics and control measures, this book is an essential reference for anyone seeking to prevent and manage concrete corrosion in sewer systems.

Sewer systems are a principal element of infrastructure in modern cities, accounting for massive amounts of public investments made over many decades and can be considered as an asset of the nation. Many concrete manholes in the sewer system are deteriorating due to the attack of sulfuric acid produced by microorganisms in a process termed as Microbial Induced Concrete Corrosion (MICC). The life span of concrete sewer elements significantly reduces from 100 years to 30-50 years, in extreme cases even down to 10 years. The primary aim of this study is to enhance the understanding of the correlation between gas-phase hydrogen sulfide (H2S) concentrations, which lead to MICC, and sewer environmental factors, including dissolved oxygen (DO), biochemical oxygen demand(BOD5), sulfide, sulfate, temperature, and pH. In addition, the effects of seasonal variations on H2S concentrations and the impact of manhole categories including the depth, velocity, turbulence and drop are also studied. For 130 manholes in the City of Arlington, Texas, the wastewater characteristics in the gas phase such as temperature, relative humidity and hydrogen sulfide were measured in-situ using various instruments and the liquid phase parameters like dissolved oxygen (DO), pH and temperature were also measured in-situ. The samples for measuring the biochemical oxygen demand (BOD5), sulfate, total and dissolved sulfide were collected in-situ and were analyzed in the laboratory using standard methodology. The sewer system characteristics like slope and velocity were obtained from the city. In each manhole studied, H2S concentration, liquid phase temperature, and liquid phase pH showed similar hourly trends in consecutive days of sampling. The trend in rise and fall of concentration of these parameters over time showed slight variations depending on the manhole's location and category. The manholes with hydraulic jump generated the highest average H2S concentration, and the lowest was observed in manholes with subcritical flow in upstream and downstream. The average liquid phase temperature was always greater than the ambient temperature inside a manhole, with a variation of 3°F on an average. In all the manholes studied for seasonal variation, the concentration of hydrogen sulfide was found to be maximum during the summer, when the temperature was elevated. Due to involvement of multiple parameters affecting each factor, no strong linear correlations were obtained between the factors studied.

Microbial induced concrete corrosion (MICC) occurs in concrete wastewater infrastructure when sulfate reducing bacteria (SRB) produce hydrogen sulfide (H2S) gas. The internal pH of fresh concrete is typically in the range of 12 to 13. Exposure to hydrogen sulfide gas may cause an acid-base reaction with carbon in the concrete, reducing the surface pH. As corrosion progresses and a biofilm develops on the concrete surface, sulfur oxidizing bacteria (SOB) react with hydrogen sulfide to produce sulfuric acid (H2SO4). This process reduces the pH within the concrete, potentially leading to the dissolution of the hydration products, such as calcium-silicate-hydrate (C-S-H), of the cement and deterioration of concrete. Corrosion rates as high as 1 cm/year have been measured in some concrete wet wells. Wastewater infrastructure in Mahoning County, Ohio face similar corrosion rates in sewers and wet wells with long retention times. In the present study, methods for controlling MICC in wastewater infrastructure were evaluated through a combination of laboratory and field trials. Treatment methods were evaluated for one year to determine effective surface preparation techniques, application strategies, maintenance strategies, and best practices. Mitigation technologies considered herein include permeability reducing coatings and surface applied biocidal inhibitor to reduce bacteria growth and control hydrogen sulfide conversion to sulfuric acid. The mitigation measures were evaluated in a controlled laboratory experiment, where MICC conditions were simulated, and the results were validated in a concrete wet well. The efficacy of each treatment was monitored for one year. However, validation of the data included herein will require an additional year of investigation. The data and results included herein revealed that some mitigation measures prove viable treatment options for inhibiting MICC.
