Water Supply Project
Tanzania-Erangau
Community Background: The project is located in the Erangau (also referred to as “Rangau”) Community of Tanzania. The community is located within a few kilometers of the Olmoti project, completed by EWB-USA SBV and the Olmoti community in 2015. Community members from Erangau were peripherally involved in the 2015 project and expressed interest in an extension to their community as early as 2014.
Project Objectives: The Erangau community has identified the problem of unreliable local access to clean drinking water. Community members either have to collect rain water or walk at least 10 km round-trip to the nearest river source, which is surface water likely containing bacteria.
The project objectives include:
-
Providing a local, reliable source of potable water for the community of Erengau.
-
Installing a new potable water distribution network to the community including 3 tap stands, pressure reducing tanks, and main transmission line. The team gathered water demand data to ensure the system is properly sized. The water source would be the same as the first project, the Simba River, which has sufficient supply to add Erangau to the system according to MMWS (Siha District)
-
Building the technical capacity of the community to operate and maintain the system long term.
Project Scope
Assessment Trip #1 November 2022: The team assessed the needs of the Erangau Community and identified water sources that are available from the same area as the neighboring Olmoti subvillage. We collected data to understand water demands for system design and surveyed diverse members of the subvillage.
Assessment Trip #2 July 2023 : The team verified that the final design and water system location were approved by Water District and Community Leaders. The team set up agreements and a path forward with the community and local authorities. The goal is to implement a water pipeline system for the Erangau/Rangau community, a sub-village of Elerai, to gain closer connections to potable water and maintain the existing EWB-SBV water system.
Implementation Trip #1 January 2025 (Tentative) : Installation of 1 pressure reducing tank, 1 storage tank, 1 tap stand, and pipeline system from existing tank to tap stand.
Implementation Trip #2 End 2025 (Tentative) : Installation of 2 remaining tap stands, and pipeline system.
