Water and Wastewater Companies for Climate Mitigation (WaCCliM)
As of: March 2021
Water and wastewater companies are among the major energy consumers in developing and emerging countries. In the partner countries of Peru, Jordan and Mexico, the project supports pilot companies in the use of greenhouse gas emission-reducing technologies, including measures to reduce water loss, energy-efficient pumps, biogas generation and fertiliser recovery from wastewater. At the national level, the project advises the countries on how to create financing mechanisms and political framework conditions, enabling more demonstration projects. Greenhouse gas-reducing technologies are further developed and disseminated through knowledge management between the pilot companies, national and regional associations and an Internet-based knowledge platform. In this way, the project contributes to the international dissemination and improvement of climate protection approaches for water and wastewater companies.
State of implementation/results
- Baseline studies on mitigation potential, climate risks and the political and institutional framework.
- Establishment of an internet-based learning and information platform for CO2 neutrality and climate resilience of water and wastewater companies.
- Support of national climate protection contributions (NDC) in the partner countries at the interface of water and energy.
- Development of the "Energy performance and Carbon Assessment and Monitoring" (ECAM) tool and related training materials.
- Staff training for water and wastewater companies in the application and operation of climate-friendly technologies and in the use of the ECAM tool in and beyond the partner countries.
- More than 320 people from water and wastewater companies were trained in the application and operation of climate-friendly technologies and in the use of the ECAM tool in and beyond the partner countries.
- Operational and process optimisations of the pilot plants have led to annual savings of more than 10,000 tonnes of CO2 equivalents.
- Installation of energy-efficient pumps with frequency converters reduces energy consumption (40%) and GHG emissions in Madaba (Jordan).
- Optimised sewage sludge treatment in Cusco (Peru) will save 7,454 tonnes of CO2 equivalents per year, equivalent to about 3,100 flights Lima-Frankfurt-Lima per person.
- Reduction of 2,500 tonnes of CO2 equivalents per year by increasing the number of connections to the treatment plant, resulting in a 40% reduction in GHG emissions at the pilot plant in San Francisco del Rincón (Mexico).
- Project presented at numerous national and international events, meetings and conferences.
