“…The inventory related to the civil works required to build the sewer on-site following the steps of excavation, backfill and compaction, was addressed in 3 papers (Doka, 2009;Herz and Lipkow, 2002;Uche et al, 2013). To a lesser extent, an estimation of energy demand or fuel consumption was accounted in 3 papers (Remy et al, 2006;Slagstad and Brattebø, 2014;Venkatesh et al, 2009) and the use of concrete and aggregates for pipes bedding was included in 7 papers (Borghi and Gaggero, 2008;Doka, 2009;Gagnon et al, 2008;Herz and Lipkow, 2002;Remy et al, 2006;Slagstad and Brattebø, 2014;Uche et al, 2013). Finally, none of the papers included the paving of the roads using bitumen, which is a product of the petroleum refining industry, whose environmental burdens can be significant because it is energy and resource-intensive (Santero et al, 2010).…”
