Tetra Tech worked with local governments and communities in Tanzania to improve water resources; water, sanitation, and hygiene (WASH) services delivery; open defecation free status; and promote resilient communities in the face of a changing climate.

Although Tanzania has abundant natural freshwater resources, its rural population has limited access to safe water and sanitation services. The Government of Tanzania recognizes that improved management of its water resources is a foundational prerequisite to achieving and sustaining the nation’s long-term development goals, including providing basic water supply and sanitation services to enable economic prosperity and social well-being. However, water security challenges are increasing due to population growth and the effects of climate change. Reliable access to safe drinking water and sanitation services is still unattainable for many people.


The Water Resources Integration Development Initiative (WARIDI) Activity was funded by the U.S. Agency for International Development (USAID) and improved equitable access to sustainable WASH services and environmental conservation in the Wami-Ruvu and Rufiji river basins. WASH services, water governance support, and livelihood activities are demand-driven in 20 local government authorities. WARIDI’s implementation approach emphasized private-sector partnerships for efficiency and sustainability, climate change adaptation that builds resilience, and gender integration and youth inclusion in water resources management from basin to households.

Through WARIDI, Tetra Tech addressed the root causes of water-related challenges impeding Tanzania’s path to sustainable social and economic development. The Activity used grants and technical support to collaboratively develop the capacity of local organizations through innovative private and public partnerships to deliver sustainable water services, solutions to monitoring and analysis of water resources monitoring and analysis, sanitation and hygiene education and behavioral change, and climate smart agriculture and water conservation training and technical assistance.

The following end-of-activity results were achieved May 31, 2021:

  • 516,067 people gained access to basic drinking water service
  • 1,278,130 people gained access to a basic sanitation service as a result of United States government (USG) assistance
  • 638 villages were verified for universal sanitation coverage of any latrine type and no open defecation
  • 6,434 stakeholders such as farmers have applied new technologies or management practices as a result of USG assistance

Morogoro District Council recognizes the great contribution by WARIDI towards implementation of development projects, especially in improving water services to the community and ensuring gender is prioritized in all development processes.
