The proposed act seeks to replace a water supply network in the area of Zarouhleika where the network is aged and very often presents damage The result of the damage is in principle the significant losses of water supply and on the other hand the inconvenience to the citizens served The replacement of the water supply network will reduce leakages while at the same time the quality of the water provided will improve due to a lower frequency of interventions in the network and therefore the introduction of external soil materials, etc. Reducing leakages reduces and the demand for water volume therefore reduces the volume pumped from aquifers and the volume processed by the refinery In conclusion, the benefit is expected to be large both directly in natural water resources and indirectly due to a reduction in the required energy
