It was part of the volunteering and work experience programme that the students complete throughout their study programme.
Derby City Council Cabinet Member for Neighbourhoods and Streetpride, Cllr Jonathan Smale said: "The students have done an incredible job and we are very grateful for all their hard work.
"Young people often get a bad press but these students have showed just how passionate and committed many are to their local communities and to work together for the greater good."
This was echoed by St Peters Quarter Business Improvement District (BID) project manager Ian Hinds.
"I have been extremely impressed with the students' work attitude and their ability to get on with the job in hand."
The day culminated in the official switching on of the waterfall in the Market Place. It will be followed by city-wide programme of deep cleans with the aim of encouraging people to feel pride in their city.
