The campaign's mission was to:
The Mersey Basin Campaign was established in 1985 in the wake of the Toxteth riots in Liverpool. Michael Heseltine, then Environment Minister in Margaret Thatcher's Conservative government, was the driving force behind its creation. He spoke of the River Mersey at the time as "an affront to the standards a civilised society should demand from its environment". It closed its doors on schedule at the end of its planned 25-year lifespan in 2010, leaving behind a river system that is cleaner now than at any time since the Industrial Revolution.
The Mersey Basin Campaign was a partnership backed by the UK Government through the sponsorship of the Department for Communities and Local Government. It was also supported by businesses, local authorities and public agencies.
The campaign worked through two bodies: the Mersey Basin Business Foundation and the Healthy Waterways Trust. The Foundation was responsible for business and administrative tasks, as well as much of the campaign's finances, whilst the Healthy Waterways Trust is a charitable body whose main role was to administer the campaign's charitable funds. The campaign was overseen by its council, which had around 30 members drawn from various public and private sector partners. The Healthy Waterways Trust remains in existence following the end of the Campaign, and continues to advocate for improved water quality and waterside regeneration in the Northwest of England.
The Campaign's last Chair was Peter Batey, Lever Professor of Town and Regional Planning at the University of Liverpool, who served from 2004-2010.
