The cleaning blitz was kick-started with action in the Ajuda neighbourhood, carried out in several locations within the parish on Tuesday between 8am and 1pm.
A team of police officers and town hall urban hygiene workers and inspectors was put together to supervise and carry out the work.
As well as sprucing up the city, the initiatives aim to raise awareness among the neighbourhoods as to what can be done on a daily basis to keep the areas clean, and the importance of complying with rules and regulations.
More action will be carried out in and around the city throughout the rest of the year; local populations will be given forewarning of the interventions.
