Restraining techniques ensure that piping stays connected and helps prevent breaks that can shut down wastewater systems.
Mechanical joint piping connections such as 45s, 90s, end caps and hydrant connections are common points of restraint as are connections in lift stations and treatment plants.
Restraint of inline piping is so widely used that it has become standard procedure among city or project engineers. Instead of using restraints for specific applications, some engineers use them throughout force main wastewater systems. However, adding restraints in this way can increase project costs significantly. There are standards to follow and techniques to apply for restraining pipe
