Since 2006 Tetra Tech has supported Engineers Without Borders (EWB) through corporate sponsorship and our EWB USA grant program. Tetra Tech is involved in projects that bring sustainable engineering solutions and provide local community members the knowledge to maintain and monitor these projects. Projects include water distribution systems, rainwater harvesting, water supply improvements, and sustainable development of school buildings.

Our associates are involved in EWB projects in more than a dozen countries around the world. Tetra Tech is currently working on a water filtration project in San Carlos, Honduras which includes an above ground water storage tank, water treatment, and distribution system.
