Japan has built the resilience of its water supply and sanitation (WSS) services through an adaptive management approach based on lessons learned from past natural disasters. This experience offers key insights for low- and middle-income countries (LMICs) seeking to sustain and build resilience of WSS services.

Sustainability of Essential WSS Services at Risk Natural disasters have increasingly damaged WSS facilities and infrastructure, leaving entire communities without safe and reliable drinking water and the appropriate disposal of wastewater. These emergency events could arise from inundation of facilities, loss of electricity, and exposure and disruption of infrastructures. Lesssevere impacts can arise from increased siltation of reservoirs and slow-onset events such as droughts, thus having longer-term effects on the resilience and reliability of services. These WSS service failures or interruptions could set off a cascading effect across interconnected infrastructure systems including public health and fire services, which in turn could pose both direct and indirect economic impacts.
