The use of ductile iron pipes in karsted areas

Summary

In providing for the integrity of water and wastewater pipelines the correct choice of pipe material is very important. For many years the main pipe materials in the public water supply systems in Russia have been steel and cast iron. Lately ductile iron pipes have competed with polymer and steel pipes. The wide use of ductile iron pipes in drinking water supply systems until later has been inhibited because of the lack of an adequate regulatory environment. Introducing amendments to Construction Rules 66.13330.2011 «Design, construction of pressure water and wastewater networks with the use of ductile iron pipes» related to the use of ductile iron pipes in karsted areas will enhance the volume of drinking water pipeline construction in difficult geological environment. The amendments have been adopted by the RF Ministry of Construction and will be put in force starting from August 5, 2017. Reducing the cost of constructing new and reconstructing the existing utility systems in karsted areas with the use ductile iron pipes is ensured by improving their life cycle, integrity, environmental safety and reducing water losses.
