Interviewees: Margaret Howard, Lavinia O'Connor and Dorothy Macedo, Protesters
A group of Southern Water customers have demonstrated outside the company's headquarters in Worthing calling for an end to the privatisation of the industry.
It claims bringing England's water companies into public ownership would save £2.3 billion every year.
Southern Water refused to comment on the protest.
The company now faces criminal prosecution for trying to cover up equipment failures that led to waste water polluting the environment.
Nationalisation would risk turning back the clock to the days when service and quality failures were far more common, the environment was suffering as a result, and cash-strapped governments wouldn't pay for the improvements needed."
