Nearly 200 fines have now been handed to litterbugs and fly-tippers in Hounslow this year after the latest crackdown.
Enforcement officers handed 11 on-the-spot fines to businesses and individuals caught illegally disposing of waste in the space of two days last month. They also issued formal warnings to five firms under the Environmental Protection Act.
A total of 187 fines for littering have now been issued in the borough since January, adding up to £12,600.
The latest round of fines included six Fixed Penalty Notices (FPNs) for individuals or businesses caught littering or illegally disposing of waste, and five for those leaving domestic refuse on the streets outside of collection days.
Deputy council leader Amrit Mann said: "Our clampdown on litter louts, fly-tippers and those selfish few who spoil our streets will be relentless.
"Like most people who live in Hounslow, I want our streets to be the cleanest in the capital. Everyone should be proud to live in Hounslow."
The fines were handed out by officers from Hounslow Highways, the council contractor responsible for street cleaning in the borough.
A council spokesman said new CCTV cameras located at fly-tipping hotspots had provided valuable evidence to help catch and prosecute repeat offenders.
A survey earlier this year suggested the council's new zero tolerance approach to littering was helping to clean up Hounslow's streets.
