The use of polymer pipes in water supply and wastewater disposal systems of Irkutsk

Summary

Water supply and wastewater disposal systems in many Russian cities including Irkutsk are characterized by long term operation, high wear and failure rate. Rehabilitating obsolete water and wastewater networks, upgrading their parameters to the actual loading as well as meeting the current sanitary-hygienic regulations, technical and economic requirements have been the critical tasks that cannot be solved without the use of advanced technologies, materials, structures and devices. Using the example of Irkutsk city the use of trenchless technologies of water and wastewater networks construction and rehabilitation with polyethylene pipes is described. These technologies provide for reducing costs and water supply interruption periods, improving conditions of work, improving the integrity and seismic resistance of the pipelines and facilities. The practical experience proves the high technological and economic efficiency of this method. The data on the use of additional engineering tools for handling pipes made of different materials is given.
