According to the World Health Organization, more than 600 million people worldwide lack access to safe drinking water and more than 2.4 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 infrastructure and international development firms, Tetra Tech leverages its core expertise in science and engineering to expand access to sustainable water and sanitation services. We also use this expertise to address countries' wider water resources challenges such as climate resiliency and adaptation issues.

Tetra Tech works with donors, government agencies, local partners, and consumers throughout the project life cycle. From providing sustainable access to clean water and promoting effective sanitation management solutions to modeling the effects of a changing climate on water resources allocations, our projects address every aspect of water resources management from watershed to water point. We work with national and local stakeholders to strengthen the provision of water and sanitation services, thereby improving public health and contributing to economic growth.

Our water resources team uses proven expertise to address the most pressing water security and sanitation challenges of our time.
