People caught dropping litter, including chewing gum, cigarette butts and spitting, or leaving dog mess behind in Bristol could face on-the-spot fines of up to £75.
The city council will introduce the tougher enforcement measure on 6th November, which includes fines for people who deface property with graffiti.
It will run an initial pilot project in the city centre with Kingdom, which works with local authorities to tackle environmental crime, with plans to expand it if successful.
People who don’t pay their fines could be taken to court and incur costs of up to £2,500.
According to the council, street cleaning currently costs around £6 million a year and last year, around 7,000 tonnes of waste was collected.
The new initiative comes after Mayor Marvin Rees launched the Clean Streets Campaign.
Mayor Marvin Rees said: “Litter remains a huge issue for the city. For this reason, we have decided to take a tougher stance on enforcement and are bringing in a specialist company to help us target people who continue to think it is acceptable to use Bristol as their own personal dustbin.
“We will not tolerate mindless littering in Bristol, it is time for us to take pride in our city and stamp out this thoughtless behaviour.”
