Water, Sanitation, and Hygiene

According to the World Health Organization, nearly 800 million people worldwide lack access to safe drinking water and more than two billion lack access to improved sanitation.

The inadequacy of these services results in depressed economic development, poor health outcomes, and a restriction of human potential.

As one of the world’s premier water resources and international development firms, Tetra Tech is Leading With Science® and leveraging its core expertise in engineering to expand access to sustainable drinking water and sanitation services. We also address wider water resources challenges in emerging economies including climate resiliency and adaptation.
