With funding from the Investment Facility for Latin America, the regional technical cooperation project, Wastewater Treatment and Reuse in LAC (RG-T3478), aimed to integrate the concept of the circular economy into water and sanitation agendas across Latin America. The initiative sought to increase understanding of regional challenges and promote the reuse of treated wastewater. Additionally, the assignment focused on exploring innovative and efficient solutions that align with local needs and contribute to achieving the SDGs in sanitation.
The assignment was structured around three main components:
1) Regional diagnosis and tool development
2)Design of treated wastewater reuse programs
3) Training in wastewater treatment
Under the Project, WE&B successfully developed/delivered the following services:
• As part of Component 1, WE&B documented and systematized experiences from 10 wastewater reuse projects or programs across the region. These 10 cases, selected from the Latin American and Caribbean (LAC) region, were chosen for their representativeness and emblematic nature, reflecting a variety of contexts, water reuse applications, and motivators for reuse. The selection also considered country-specific variations and geographical scope. This comprehensive effort helped identify key lessons learned, while establishing criteria and incentives for wastewater reuse that could be applied across different contexts within the LAC region.
• To prepare an information collection sheet for each case, integrating data on the case context, technical, financial, and environmental aspects, while documenting encountered barriers.
Key outputs and deliverables:
• Deliverable 1: A preliminary report presenting a proposal of cases to be analyzed, including the corresponding information collection sheets.
• Deliverable 2: A final report on the 10 most emblematic water and sludge reuse cases, along with the identification of lessons learned.
