Abstract: This study focuses on the drinking water distribution network (DWDN), presenting the environmental analysis of 2 pipes made of high density polyethylene (HDPE) and poly vinyl chloride (PVC) for the construction of the DWDN applying the life cycle assessment (LCA) methodology. The results show that PVC scores better than HDPE in 2 out of the 7 midpoint impact categories analysed. However, these differences are not high enough to consider PVC environmentally preferable. Most of the environmental impacts are generated during the installation of the pipe, although the other phases (production and transport of the pipe) also contribute with significant environmental impacts and must be considered for the reduction of the DWDN impacts.
