Ruling paves way for businesses and public to sue water

Decision by supreme court means water companies could be sued for damage caused by dumping of human waste

Water companies could face a spate of legal challenges by people and businesses affected by sewage pollution after a landmark ruling found United Utilities can be sued by a private company for damage caused by the dumping of human waste.

Lawyers said it was a “watershed moment” as the courts had previously ruled that penalties for water companies were a matter for the regulator, and companies could not sue firms for damage caused to their property by sewage pollution.
