Only 83 megalitres of Harare waste water is being treated to the correct effluent quality allowed by the Environmental Management Agency (EMA).
The rest of the 240ml, which is received per day, is sent back into the system as secondary level quality according to Council.
The Acting Director of Harare Water, Engineer Mabhena Moyo, confirmed this and added that some of the “waste water (is) treated to secondary level quality and released to irrigate pastures in Council’s cattle farms”.
The Town Clerk, Engineer Hosea Chisango, added that the main challenges were to do with investments to enable Council to utilize the full design capacity of the Sewer Treatment Plants.
“There have also been numerous breakdowns at such plants whilst funding of requisite treatment works has also been a major constraint”.
In an effort to deal with the constant breaking down of digesters, which has been undermining waste water treatment, Council has resolved to sell some of its cattle so as to finance the rehabilitation process.
The City is also currently pursuing a number of Expressions of Interest (EOIs) in Waste Water and Water Supply in the City.
Harare’s waste water treatment plants are Firle, Hatcliffe and Crowborough.
The current capacity of the plants is below the volume of waste water generated in the city and the Acting Director of Harare Water has since advised that a contractor is working on electrical and mechanical components which are at 90% stage of completion.
Council expects the electrical and mechanical works to significantly increase the volume of treated waste water.
