The quest for sustainable water resources in Tanzania

Egis conducted studies to seek out safe, reliable and sustainable water resources for the local population of Arusha (Tanzania).

Date : 2016
Duration: 9 months
Client: Arusha Urban Water Supply and Sanitation Authority (AUWSA)
Funding: African Development Bank

Project overview

Arusha is located in the midst of major national parks and volcanoes and is one of Tanzania’s major tourist hubs.

The local water utility AUWSA provides drinking water to a population estimated at 550,000 in 2015, however, forecasts indicate that demand for water is set to soar by 50% by 2030. With a view to meeting current and future requirements, AUWSA has commissioned.

Our missions

Egis compiled an inventory of all existing underground and surface water resources. The study is part of a wider programme to provide sustainable potable water and waste treatment services to the city of Arusha. It is based on 60 geophysical profiles and 12 test holes bored at an average depth of 250 m. Rivers originating and flowing around Mont Meru and Daluti crater lake will also be subjected to a qualitative and quantitative analysis.

After nine months of surveys, AUWSA is equipped with a development strategy that reflects its capacities in terms of drinking water production and related waste treatment.

The operation is funded by a loan from the African Development Bank and is in phase with the goals set out in Tanzania Development Vision 2025, designed to combat poverty and improve living conditions, notably by developing basic infrastructure. Improving water access also has benefits in terms of climate change adaptation and water source management and will help curb water-borne diseases and reduce care requirements.
