Inspection, Design, Installation Guidelines When Relining Sewer Manholes

摘要

Sanitary sewer pipeline collection systems and manholes are a vital component in every city's infrastructure. These systems are designed to transport wastewater to treatment facilities. When infiltration enters the sanitary system through the sewer manhole, it creates a multitude of problems at the treatment plant, including sanitary sewer overflows (SSO's). The occurrence of these events are under strict government guidelines and are a serious threat to public health. Infiltration causes treatment costs to rise and may create the situation where newer large treatment plants must be constructed to handle the wet weather overflows.
