A £3 billion investment programme is being planned by Yorkshire Water, with almost half the huge sum set to be used to substantially reduce sewage outflow.
A decade of capital investment delivery - the largest yet - is being put to market now, as the utility provider looks to secure contractors to work on vital schemes.
The stormwater programme will see around £1.3 billion spent on reducing overflows into watercourses, with Yorkshire Water looking to procure an alliance to complete the work. It comes against a backdrop of national criticism of water companies - and the passing of legislation by government that has allowed it - for the levels of waste entering the streams, rivers and the sea.
