摘要

For most of its history, the trench-less pipe relining and inspection market has centered on gravity sewer pipes.That seems quite natural, considering the fact that the cured-in-place pipe (CIPP) process - the forerunner of trenchless relining - was engineered specifically for gravity sewers. In the United States, U.S. EPA consent decrees enforcing the Clean Water Act mandated that sewer improvements be made across the country to reduce the number of sewer overflows into the environment. This helped fuel the growth of trenchless relining, even through the most recent economic downturn that crippled many industries. Aiding in this development is the fact that sewers do not have the rigorous testing and approval process needed to meet drinking water standards.
