- The operational energy of water's distribution (energy consumed during pumping and
water transfer).
Although the wilaya of Algiers' statistics do not describe the material that constitutes the pipe
of the water distribution network, the EF of the embodied energy was calculated, assuming
that this material is HDPE (lower emission factor).
The operational energy for water production and the transfer was provided by the
SEEAL/Tipaza for the year 2020 (production = 11.4 GWh, transfer = 22.5 KWh) for more than
20 million m
3
(produced) and 34 million (transferred). This data was included to model the
energy consumed for one m
3
of drinking water and define the equivalent EF_c.
The EF of the built area is associated with the area occupied by water capture infrastructures,
i.e., artificial water dams, including the Koudiate Acerdounedam in Algiers and the Meurad
dam in Tipaza. The calculation results of the EF_c and EF_built are described in the table 26
and figures 8 and 9.
