DAR ES SALAAM City is lined up for three major sewage treatment plants estimated at 600m US dollars (about 1.320trl/-).
The ambitious plans will enable the
country’s commercial capital to boost its capacity of treating sewage
from 10 per cent to 30 per cent by 2020.
What is more, the pipeline currently
discharging the unwanted liquid into the Indian Ocean will be diverted
to a plant to be set up at Jangwani area, according to Acting Chief
Executive Officer of Dar es Salaam Water and Sewerage Authority
(DAWASA), Eng Romanus Mwang’ingo.
The Acting CEO explained that the treatment dams would be constructed at Jangwani, Kurasini and Mbezi Beach.
They will be designed in a way that they will generate their own power through biomass to operate the plants.
“Treated water from the plants will be
used for other purposes such as cooling of industrial parts and
irrigation while the remainder will be used as manure for agriculture
and gardens in the city,” the DAWASA boss said during a news conference
at the Tanzania Information Services (Maelezo) auditorium.
The Jangwani plant, to be constructed at
a cost of 90m US dollars (about 198bn/-), will have the capacity to
treat 200,000 cubic metres per day and it will include a pipeline
network running from Ubungo to Jangwani.
Eng Mwang’ingo said the network would branch off to Kinondoni, Mwananyamala, Msasani, Ilala and the central business district.
First phase of the project will have a
plant with the capacity to treat 25,000 cubic metres per day, covering a
pipeline network of 17.43 kilometres from Magomeni to Jangwani.
“During this phase, the pipeline discharging sewerage in the ocean will be diverted to the plant.
The project is being funded by the government of Korea through Exim Bank and the funds have been availed already,” he explained.
At Mbezi Beach, the treatment plant will
be set up at Kilongawima area and will be able to process 16,000 cubic
metres of sewerage per day, it will consist a network of 97 kilometres
covering Mbezi Beach, Kawe, Tegeta and surrounding areas.
“This project is designed to cost 65m US
dollars (approximately 143bn/-) and funded by the World Bank. We are
now awaiting a permit from the bank to start inviting contractors to
implement the project,” he explained.
The Kurasini plant will cover a network
of 90 kilometres from Keko, Chang’ombe, Kurasini, Temeke and National
Stadium and will have a capacity of treating 11,000 cubic metres per
day.
The costs of the project are still being analysed but it will be financed by French Development Agency (AFD).
