Assessing population coverage of safely managed wastewater systems: a case study of Lebanon

This paper presents the evaluation of the proportion of the population connected to safely managed wastewater collection systems (PW) based on the proportion of population connected to wastewater collection systems and additional specific indicators that can properly inform on the extent of environmental risks associated with the disposal of wastewater. A safely managed wastewater factor (SF) is proposed to take into consideration the environmental risks when evaluating PW. At the practical level, results of evaluation of the proposed PW and SF indicators in Lebanon are then presented and discussed. Finally, the conclusion and further developments are presented.
