Cape Town is in the middle of a serious water crisis that will see the city running out of water by March 2018 if nothing changes.

Third year Univeristy of Cape Town civil engineering student Nkosinathi Nkomo, who couldn't register this year due to lack of funds, has a solution for the crisis.

He invented a device that will recycle water from the bathroom, and filters it for irrigation.

But grey water isn't a new thing, so what makes his device different?

"The main challenge with grey water devices currently is that they are very expensive to manufacture and maintain, so the main challenge was to come up with an affordable solution," Nkomo tells eNCA in an interview.

The normal price for a grey water system in South Africa usually starts at R5 000. Nkomo's prices will start at R3000 depending on the size of the household.

Nkomo is assisted by three of his friends. Sesethu Mazangazanga as project manager; Njabule Gule is responsible for operations; and Monica Masetola does branding and marketing for the company.
