Thwake Dam
Dam complex in Kenya
From Wikipedia, the free encyclopedia
The Thwake Dam or Thwake Multi-purpose Water Development Programme, is a dam complex being built on the Athi River in Kenya.[1][2] The dam is meant to be a multipurpose dam that provides drinking water, agricultural irrigation water, hydropower, and other water supply infrastructure.[1] Water storage is 688 million cubic metres and is meant for rural homes, Konza and other local jurisdictions.[1][2] The dam cost KSh. 37 billion and is being built by the China Gezhouba Group Company.[3] The Funding was provided by the African Development Fund.[4]

Phases
The construction and implementation of the project were divided into four phases:[5]
Phase 1: Construction of the structural dam wall and spillway downstream of the Athi and Thwake rivers. The wall is 80.5 meters high, holding 688 million cubic meters.[6] The construction started on March 27, 2018 and its completion was to be in November 2022 but was delayed due to funding and Covid-19 pandemic and is set to be completed by June 2025.[7][8]
Phase 2: This is to implement the dam's hydropower system with a capacity of 20 MW and water treatment plants.[9]
Phase 3: Focuses on the water supply and sanitation infrastructures to serve the populations around Kitui and Makueni. A water waste management system was also developed as part of this phase.[5]
Phase 4: This is aimed at the development of the irrigation scheme around the dam to cover 40,000 hectares.[5]
pollution concerns
The need for potable water from the dam led to a number of conservation projects upstream, trying to create better clean water, such as in Ondiri Wetland.[3] Moreover, many industries had been discharging directly into the river.[3] In July 2021, the dam was criticized by auditor Nancy Gathungu for the lack of clean and safe water to be retained due to pollution locations like Athi River.[1][10]
