WASHPaLS Final Report


The final report from USAID’s Water, Sanitation, and Hygiene Partnerships and Learning for Sustainability (WASHPaLS) Project covers the full period of implementation from September 16, 2016, to February 24, 2022, and presents the project’s major achievements and notable challenges.

WASHPaLS was a five-year task order awarded to Tetra Tech on September 16, 2016, under USAID’s Water and Development Indefinite Delivery Indefinite Quantity Contract (WADI). Tetra Tech implemented the project in collaboration with several nongovernmental organizations and small business partners—Aquaya Institute, FHI 360, FSG, and Iris Group. These partners contributed expertise in state-of-the-art water, sanitation, and hygiene (WASH) programming and research. Distinguished academics, practitioners, and policymakers from across the WASH sector provided expert perspectives regularly to the project through an internal research working group and an external Advisory Board.

WASHPaLS supported USAID’s goal of reducing morbidity and mortality in children under five by ensuring USAID programming employs high-impact, evidence-based environmental health and WASH interventions. WASHPaLS identified and shared best practices for achieving sustainability, scale, and impact by generating evidence to support the reduction of open defecation and the movement of communities up the sanitation ladder, while also focusing on novel approaches for reducing infants’ and young children’s exposure to feces. 

WASHPaLS #2 builds on the findings and recommendations of WASHPaLS and aims to strengthen USAID’s WASH programming at country-level and enhance global learning and adoption of the evidence-based programmatic foundations needed to achieve  sustainable development goal (SDG) 6.2, particularly in rural areas.
