Maintaining the quality of sewer pipeline rehabilitation
with the use of flexible polymer liners

Summary

The technical condition of sewer pipelines in the Russian Federation is deteriorating with each passing year. Under the federal project «Upgrade of Public Utilities Infrastructure» 4.5 trillion rubles will be allocated for the major repairs and reconstruction of water supply and sewer networks by 2030. The effectiveness of investments is determined primarily by the quality of construction and the durability of the networks after repair and rehabilitation. A modern approach to maintaining the quality of sewer pipeline rehabilitation using flexible polymer liners is presented in the paper. This technology has gained deserved acceptance among the professionals as a cost-effective solution for eliminating within a short time a wide range of pipeline damage. Implementing a quality maintaining system for pipeline rehabilitation using flexible polymer liners will not only provide for the long-term, trouble-free operation of pipeline systems but also for the improvement of the effectiveness of import phase-out efforts.
