Polluters like Thames Water Utilities Ltd. that befoul UK rivers and seas will face unlimited penalties and tougher sanctions, according to new government legislation announced on Wednesday.

“We are scrapping the cap on civil penalties and significantly broadening their scope to target a much wider range of offenses – from breaches of storm overflow permits to the reckless disposal of hazardous waste,” Environment Secretary Thérèse Coffey said.

The legislation follows a consultation by the Department for Environment, Food and Rural Affairs, which examined the pollution of UK rivers and seas with sewage and untreated wastewater. The government’s ‘Plan for Water’ intends to strengthen regulation and prevent companies from accepting fines in lieu of paying the high costs of treating their sewage.
