25 years ago Princess Anne, The Princess Royal, opened Liverpool Wastewater Treatment Works - the River Mersey was then known as one of the dirtiest rivers in Europe, awash with a deadly cocktail of raw sewage and toxic chemicals.

The improvement in treating wastewater had an instant impact, helping the river Mersey to flourish once again, key to the economic regeneration of Liverpool.

This week The Princess Royal returned to Liverpool to open the new state-of-the-art extension to the existing treatment works.

The success of the clean-up is evident. Beautiful creatures such as dolphins frolicking in Liverpool Bay are becoming a common sighting and a humpback whale was recently spotted flapping its distinctive pectoral fin.
