In South Africa, the City of Johannesburg is set to release a tender for a 3MW in-pipe hydropower scheme. This announcement was made by Johannesburg executive mayor Parks Tau at a conference last week.

Addressing members at the Association of Municipal Electricity Utilities (AMEU) conference, Tau said: “The City is in the process of harnessing energy from water flowing through the vast labyrinth of the waste water pipes network traversing the City – using in-pipe turbines.

“We are working with the University of the Witwatersrand to develop ICT solutions to meet the challenges that the City is facing today and those foreseeable in the future.”

In-pipe hydropower project scope

The preliminary work on the in-pipe hydropower project has been completed and the first 3MW of in-pipe power is expected to be introduced in Q1 of 2016, according to MD of City Power, Sicelo Xulu.

Xulu added that City Power has visited the site and met the National Energy Regulator of South Africa to ensure they are eligible for a generation license through the in-pipe turbines, Construction Review Online reported.

Technology benefits

According to media, it is projected that the project could contribute 10MW of electricity over the years, which would be generated through the city’s bulk water network.

Earlier this year, Tau spent three days in the US city Portland, Oregon, where he evaluated the feasibility of an in-pipe hydropower system, which proved to be a model that could be implemented in South Africa.

The City of Johannesburg is working closely with the city’s water utility, Johannesburg Water (JW), on this project. JW’s managing director, Lungile Dhlamini, said that the pilot project could provide the utility with 10% of its energy consumption needs.
