Posy Sterling stars in Dirty Business on Channel 4.

Based on a decade-long investigation into England’s water companies, and telling the real stories of whistleblowers and victims who believe their lives have been destroyed after encountering sewage polluted water, Dirty Business is a major new factual drama investigating one of the biggest potential corporate scandals in British history.

Dirty Business follows the story of two unlikely detectives, who notice that the fish in the river running through their idyllic Oxfordshire hamlet are dying. They contact their water company to find out why, and the company’s strange and evasive reply sparks an investigation that remains ongoing to this day.

Dirty Business begins on Channel 4 at 9pm on Monday 23rd February.
