Brent council have hired private security firm Kingdom, to run a 12-month pilot of issuing fixed penalty notices (FPNs) to anyone caught littering in the area.
Uniformed police offers will be able to hand any one caught in the act of committing a waste offence, including littering, paan spitting and not cleaning up after their dogs, an £80 fine.
Dedicated patrol officers will be deployed to hot spot areas in the borough with the purpose of issuing FPNs and Brent Council has been working closely with Veolia, the waste and recycling contractor, and both residents and councillors to identify particular areas known for littering and dog fouling for enforcement activity.
Paan spitting, by people who chew a mixture of tobacco and leaf, leaves red splodges on the floor, and signs are displayed in Wembley urging people not to do it.
Cllr Eleanor Southwood, Brent Council's cabinet member for the environment, said: "The vast majority of residents here in Brent love where they live and take great care of our streets and parks.
"More and more residents are working with us to keep the borough clean by reporting illegally dumped rubbish via the Cleaner Brent app and organising their own clean up days.
"It's really frustrating that there are still a minority of people whose actions are spoiling Brent for the rest of us.
"We're determined to take action against this anti-social behaviour. I hope that the possibility of getting a fine will make people think twice before dropping litter or allowing dogs to foul our pavements.
"We want to make it as easy as possible for everyone in Brent to get rid of their waste legally, to recycle more and take greater care and pride in the local area.
"This pilot scheme is part of our Love Where you Live campaign and sends a clear message that choosing to drop chewing gum or flicking a cigarette butt instead of disposing of it properly will have very real consequences."
