A University of Zambia (UNZA) electrical engineering student has proposed for a micro power station on Lusaka’s Ngwerere waste water stream to provide domestic and irrigation power to the community.
Wamundila Akabondo said the establishment of the micro hydro on Ngwerere stream would go a long way in supporting irrigation farming
and domestic power  in the area.
“This project would help the farming community access domestic and irrigation power which can be generating at their door-step,” Mr
Akabondo said.
He said this in a presentation dubbed ‘Design and Implementation of a Micro Hydro Power Station on Lusaka’s Ngwerere Waste Water Stream’ during  the Engineering Institute of Zambia (EIZ) Paperate Competition held at  Kitwe’s  Pamo Hotel last week.
The proposal earned him a third slot which was shared with Francis Chewe who did a proposal on  determination of total heat load when mining the deep section below 1457 meter level at Mufulira mine.
The proposed project seeks to design 51 kilovolts enough to power around 300 framing community along Ngwerere stream.
Meanwhile, Copperbelt University (CBU)’s Luhanga Mbela who successfully defended fabrication of the grain sieving machine design proposal by scooping the first award, said increased demand of  effective and efficient methods of sieving in food processing industry can lead to
alternative methods of sieving.
“The conventional (hand) sieving method is laborious and time consuming, hence the design of an agitated grain sieving machine whose aim is to design and fabricate a working prototype to generate concepts and select the best concept.”
The method used included selecting one type of beans, interview traders on the average beans grades on demand while developing concepts aimed coming up with the best impression.
Others were selecting materials ,build a machine thereby conducting tests and experiments for best results among others.
