Harare water's quality to improve

HARARE - Harare's water quality is set to improve as the lift that enables engineers to get to turbines that draw water from Darwendale Dam has been fixed.

During a recent tour of Morton Jaffray (MJ) Water Treatment Works and Lake Chivero, acting director of Harare Water Mabhena Moyo said the lift which goes down a shaft of more than one kilometre would be commissioned soon.

The lift which has not been working for five years goes down a tunnel that has a pipeline which links MJ with Darwendale Dam, where Harare City Council (HCC) engineers draw water from the source which is more than 15 kilometres away.

“The lift was fixed and is now working. All that we are awaiting is for it to be inspected and approved for use by National Social Security Authority inspectors so that we can start working. Maybe in the next 10 days we will be drawing water from Darwendale,” Moyo said.

He added that once engineers go down the shaft, they will look at some equipment which had been lying idle for more than three years as they needed repairs and maintenance.

Mabhena said the water from Darwendale Dam would be used to dilute the concentrated water from Chivero which was now full of algae.

“If we have too much algae, the filters clog and the clarifiers quickly fill up with dirt. To alleviate that problem we need to use clean and treated water. When that water comes a lot of it will be lost to backwashing as we try to clean the filters and pipes once the process starts but that is to ensure that we pump out quality water to residents,” he said.

Mabhena said at present there was no other way but to ration water as there was not enough water in the lake for everyone.

“We know that there are suburbs like Mabvuku and Tafara which have not been getting water but we assure you that some suburbs which have 24/7 supply of water will have some days when they will not have water so that we distribute it as equitably as we can,” he said.

Harare which now has an 18-month reserve of water from Lake Chivero has a demand of 1 200 mega litres against a supply capacity of 704 mega litres.
