Water sector
The emission factors considered in this study are those associated with pipeline
manufacturing. The water distribution network of the wilaya of Tipaza combines several types
of pipelines: delivery, distribution, and desalination. Along its whole length, the distribution
network comprises various materials, mainly steel with a diameter of 150 mm, iron with a
diameter varying between 250 and 900 mm, PVC with a diameter of 100-200 mm, HDPE with
a diameter of 60 to 300 mm and other materials.
In a conservation approach, this study assumes that the pipelines are HDPE, which is the
material with the lowest CO2 emissions according to the United Nations Environmental
Protection Agency WARM document. Indeed, HDPE is associated with an emission factor of
0.39 Mt CO2eq. Furthermore, based on the literature (norm 23.040.20 for plastic pipeline), the
