Peru’s urban water sector on the path to carbon neutrality

Project description

Title: Water and wastewater companies for climate mitigation (WaCCliM)  
Commissioned by: German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) in the framework of the International Climate Initiative (IKI)
Country:​​​​​​​ Global, Jordan, Mexico, Peru
Lead executing agency:​​​​​​​ In Peru: Ministry of Housing, Construction and Sanitation (Ministerio de Vivienda, Construcción y Saneamiento – MVCS)
Overall term: 2013 to 2022



Peru’s water and wastewater companies face challenges such as the damage to water infrastructure caused by heavy rainfall and floods, and changes of water availability caused by the melting of the Andean glaciers. Climate change is further exacerbating these challenges. At the same time, energy-intensive water and wastewater systems are producing high greenhouse gas (GHG) emissions.


Urban water and wastewater companies in Peru reduce their GHG emissions and simultaneously improve their level of performance.


The project is supporting SEDACUSCO, the water and wastewater utility in the city of Cusco. It has optimised sludge management, and this has already enabled SEDACUSCO to avoid emissions of more than 7,800 tonnes of CO2 equivalent per year. The amount of untreated sludge has also been reduced. SEDACUSCO is currently trialling the conversion of biogas into thermal and electrical energy with the aim of making the wastewater treatment plant self-sufficient in terms of energy, saving around 260,000 euros in annual electricity costs.

The project is also cooperating with the Ministry of Housing, Construction and Sanitation to boost the expertise of Peru’s water and wastewater companies. To this end, it is developing e-learning courses, which help the utilities to implement climate mitigation measures. Using the web-based Energy Performance and Carbon Emissions Assessment and Monitoring (ECAM) tool enables them to assess their GHG emissions and report on their progress regarding the national climate targets.

This initiative is supported by German development cooperation and implemented by the GIZ projects WaCCliM (which is responsible for mitigation of GHG emissions) and PROAGUA II, co-financed by the Swiss State Secretariat for Economic Affairs, SECO.
