| Contents Notes |
Many locations in the southern coast of the United States along the Gulf of Mexico, shown above, experience higher infiltration rates and greater maintenance difficulties with sanitary sewers than other sections of the nation. In addition to pollution costs, excessive infiltration places additional financial burdens on sewerage authorities. Thus a study was conducted of actual sewer systems to obtain and delineate information that will be helpful to those persons engaged in the design, construction, maintenance, and regulation of sewer systems. The purpose of the manual is to present the nature, status and cost of infiltration, methods of measuring infiltration, the causes, measurement and various aspects of sewer settlement, sewer bedding materials, and sewer construction in general and with respect to infiltration control. |
