The Liverpool programme - keeping the Mersey clean
We've been given the go ahead to build a £200 million extension to our Liverpool Wastewater Treatment Works (WwTW) on the banks of the River Mersey in a scheme that could create up to 350 jobs.
The existing works at Sandon Dock, Regent Road will be extending into the adjacent Wellington Dock. This will result in a plant able to cope with 11,000 litres of waste a second, equivalent to filling an average family car 200 times every second.
Treated water leaving the new plant will be cleaner and greener, helping the continuing rejuvenation of the River Mersey and ensuring it meets strict European standards for water quality.
Back in 1985, the river was the most polluted in the UK but it now sustains a wide range of fish such as salmon, trout, lamprey and dace.
Below is an image of Liverpool WwTW as it is now and an architect's image of how it will look once the new development is complete.


We have worked closely with local businesses, residents and Liverpool City Council to devise a scheme that will have a minimal impact on the famous Liverpool skyline.
The treatment facility, based on successful plants in other coastal cities, such as Cardiff and Dublin, will be sunk into Wellington Dock and coping stones, dock features and furniture will be retained where possible.
The planning application was submitted in July 2011 and Liverpool City Council's planning department approved the plans at a meeting on Tuesday 10th January 2012.
The expansion of Liverpool as a city down the years meant the current works was beginning to reach the end of its useful life. The new extension will ensure we can continue to provide one of the city's most essential services for many years to come. We estimate up to 350 people could be employed to work on the scheme.
Work will start immediately and will be completed in February 2016. Find out more about the plans and please check this page for future project updates.
