Peru is particularly vulnerable to the impacts of climate change. A low-lying coastal area, with vast arid and semi-arid lands, much of Peru is liable to floods, droughts and desertification. 72% of the total number of national emergencies are due to hydro-meteorological threats.

Already struggling to secure a reliable supply to meet user’s demand, more frequent and severe natural disasters pose an increasing burden on water utilities in Peru. Huge differences in altitudes require enormous amounts of energy to distribute the water and lead to high energy costs.

WaCCliM (the Water and Wastewater Companies for Climate Change) is working with pilot water utilities in four countries, developing a road map to guide them towards energy and carbon neutrality.

Peru, the national challenge

Peru is particularly vulnerable to the impacts of climate change. A low-lying coastal area, with vast arid and semi-arid lands, much of Peru is liable to floods, droughts and desertification. 72% of the total number of national emergencies are due to hydro-meteorological threats.

Already struggling to secure a reliable supply to meet user’s demand, more frequent and severe natural disasters pose an increasing burden on water utilities in Peru.

Huge differences in altitudes require enormous amounts of energy to distribute the water and lead to high energy costs.

Droughts, intense rainfall or mudslides also affect drinking water and wastewater services, impacting the availability and quality of water, or damaging the utilities’ infrastructure. At the same time, providing drinking water to the population and treating wastewater are energy-intensive processes, and thus forming a significant part of a utility’s overall costs.

GHG emissions in Peru

Adopting climate change mitigation measures in the water sector in Peru is an effective insurance against an uncertain resources future, and would contribute to the NDC commitments made by the Peruvian government to reduce 20% of its greenhouse gas emissions by 2030, as well as a more ambitious target of 30%. Water as a resource is one of the priority areas in Peru’s adaptation plan.

WaCCliM in Peru

The WaCCliM project in Peru cooperates with the General Directorate for Environmental Affairs under the Ministry of Housing, Construction and Sanitation, which is responsible for environmental policy in the water and sanitation sector including both mitigation and adaptation to climate change.

WaCCliM pilot utility of Cusco, SEDACUSCO, is already pioneering the way towards sustainable, low-carbon, urban water management. For a detailed account of WaCCliM’s impact in Peru, read the dossier in Spanish.

WaCCliM water utilities

In the city of Cusco, the GHG emissions reduction potential of the water and wastewater utility SEDACUSCO has been determined to be more than 50%. WaCCliM supported the pilot utility to optimise the biogas production and improve the utilities services, while also reducing annual GHG emissions by more than 5.300 t CO2e/a. This corresponds to approximately 30% of the utility’s total CO2e emissions.

Further plans to implement cogeneration from biogas will contribute to additional 650t/a CO2e GHG emissions reductions per year. The utility also plans to improve the energy efficiency of the water system through installing more energy efficient water pumps. This would further reduce GHG emissions by ~ 1300 tCO2e per year; part of the investment will be recouped due to the savings in energy costs.
