"Manhole Inspection and Rehabilitation, MOP 92, Third Edition, provides a valuable update to reflect current and complete inspection, as well as grading protocol that offers logical step-by-step guidance for maintaining and improving the longevity of manhole systems"--

Effective manhole inspection and rehabilitation is necessary to remove excessive manhole infiltration and inflow, improve manhole structural integrity, address public safety related issues, and implement general system maintenance needs. This manual provides technical guidance for implementing a successful manhole inspection, pipeline lamping, and rehabilitation program. Presented are various inspection techniques and procedures for analysis, design, and construction. Through inspections, system manhole conditions are identified, system maps are updated, and pipeline maintenance needs are evaluated.

A standard reference for all sewer system professionals. The third edition of this industry bible shows you how to develop a comprehensive sewer system. evaluation and rehabilitation program. The book explains how. to design successful rehabilitation programs, apply processes. for evaluation and rehabilitation, and appraise the results. This. updated classic features new material on tools and methods. for pipe evaluation, infiltration and inflow problems and. detection, rehabilitation materials and methods, and effective. repair methods.

Gravity flow wastewater collection systems are comprised of sewer pipes and manholes. Failure of a manhole may have catastrophic consequences such as developing a sinkhole in the street and roadway, and at a minimum, wastewater flow will be blocked and stream of the manhole will backup causing a sanitary sewer overflow (SSO). Improving structural conditions of a manhole is critical to minimize these types of failures. This thesis considers the impact of several lining materials including cement mortar, epoxy, polyurethane, cured-in-place composites, and a multi- layer structure material on increasing the structural capabilities of deteriorated manholes. The tasks included in this thesis consist literature search and, preliminary laboratory and main testing of select manhole rehabilitation materials. A finite element analysis is included to complement the experiments. Several preliminary tests according to ASTM C-39 on coated concrete cylinders, and ASTM C-293 on lined concrete beams, were performed at UT Arlington's Center for Underground Infrastructure Research and Education (CUIRE) Laboratory. The test results showed significant increase in the performance of concrete samples under compression and flexure. A second round of testing was performed on 4-ft long, 24-in. diameter concrete pipe sections with 3-in. wall thickness manufactured according to ASTM C-76. These pipe sections were lined internally with the same materials as the preliminary tests, and tested according to ASTM C-497 under Three-Edge-Bearing testing. Using computer data acquisition system, strain gages and displacement extensometers, stress/strain data were measured. The results showed that tested No-Dig manhole rehabilitation materials can significantly improve structural performance of deteriorated manholes.

This, the first of two volumes, gives a comprehensive treatment of the civil engineering work relating to sewers and emphasises the practical aspects of repair and renovation. A considerable amount of theoretical work already exists on this subject. However this book is unique in meeting the engineer's need for up-to-date information on the application of theory and incorporates some important recent developments in the field. The technical aspects of survey and access are dealt with in some detail and the book also provides fundamental data on hydraulics, structural assessment and the use of the Wallingford Storm Sewer Package.
