Introduction<\/h3>\n

Water pipes are used in water distribution networks to transport raw water from the source to the treatment plant, and to transport the treated water from the treatment plant to the house connections. Pipes are therefore a vital engineering system, as they supply consumers with drinking water. As part of assignment 2 a Life Cycle Analysis was conducted on a 1 km section of water pipe with a nominal diameter (DN) of 200.\u00a0When comparing pipes made out of the four different materials of PVC, concrete, cast iron and ductile iron, it was determined that the pipe with the least emissions during its lifetime is the concrete pipe. The most important parts of the LCA are presented below.<\/p>\n

Goal & scope of the LCA<\/h3>\n

The purpose of the LCA was to determine the environmental impacts of placing a new water supply pipe along a stretch of 1 km. Therefore, the functional unit (FU) was \u201cone km of a pipe of the diameter DN 305\u201d. The study was conducted using four different commonly used materials: cast iron, ductile iron, PVC (Polyvinyl chloride) and concrete. Environmental impacts that were considered are the following:<\/p>\n
