Yorkshire Water has been fined £45,000 after pleading guilty for polluting a watercourse with raw sewage.
The incident took place in April 2014 in Doncaster, which led to the deaths of several hundred fish, according to the Environment Agency.
Raw sewage was discharged from the water firm’s pumping station at Sandy Lane, Belle View, into a watercourse and ultimately into two local ponds.
The pollution from the illegal discharge was traced more than 3.5km downstream from the pumping station.
Richard Moore, Team Leader at the Environment Agency said: “Safeguarding the environment is an essential part of how all water companies must operate. The sentencing in this case shows we will continue to take companies to task where they fail to meet environmental standards.”
ELN has contacted Yorkshire Water for a statement.
