Early warning system for potable water supply

Potential climate/ disaster impacts addressed by approach & Justification for approach:

Peru is a country with a highly vulnerable population. Ecosystems, too, are vulnerable to climate hazards, having seven of the nine vulnerability characteristics identified by the United Nations Framework Convention on Climate Change (UNFCCC). Moreover, 62% of the country's population lives in the Pacific watershed (desert area) with only 2,2 % of total water resources, whereas the Atlantic watershed accounts for 34% of the total population with 97,3 % of total water resources and the Titicaca one makes up 4% of the total population with 0,6 % of total water resources. In this context, many water utilities struggle to deliver basic and equitable water and sanitation services, as well as meet the Sustainable Development Goals (SDG 6) and the Paris Agreement. Growing urbanization pushes an increasing demand for water resources, bringing additional challenges to cities that are already under water shortages. Moreover, expected climate change and extreme events will worsen existing problems as well as bring new ones. These hazards will increasingly require proactive planning and implementation of adaptation measures for delivering sustainable water and sanitation services. By means of an early warning system, located at the Poechos dam's outlet, the water utility of Piura city (GRAU) has increased its drinking water treatment plant's response capacity up to 24 hours.
