Ductile iron (DI) pipes are used for water and sewage transportation. In order to transport sufficient quantities of water from different sources i.e. rivers, lakes or wells, to a treatment plant with minimal loss and then transport the treated water to the end user, a reliable pipe material is required that is strong, long lasting, corrosion resistant and reduces the risk of contamination. Ductile Iron pipes possess these qualities and are currently the single most widely used type of pipe for the transportation of water & sewage.
