Outdoor bathers at places such as Knaresborough Lido will be able to get almost real time data this summer on sewage being pumped into rivers.

There has been widespread concern about the state of local rivers, especially the Nidd and Ure.

Yorkshire Water announced yesterday it had launched an interactive map that will provide current information on the operation of storm overflows.

Water companies use storm overflows to release extra rainwater and wastewater into rivers when the sewerage system is at risk of being overwhelmed.

This usually happens during heavy rainfall but there has been concern about the overflows operating at other times and pumping more sewage into waterways.

The interactive map has been launched ahead of the 2024 bathing water season, which runs from May 14 to September 30.

It shows the live status of each of Yorkshire Water’s storm overflows, when they last discharged into a watercourse and for how long. The information refreshes at 15-minute intervals,

Yorkshire has 2,180 storm overflows and Ben Roche, director of wastewater at Yorkshire Water, said the map would increase transparency for customers:

Mr Roche said:

“All the data will be available to anyone accessing the map. We have decided to launch now, ahead of the bathing water season to ensure customers are better informed about our operations in their area.

“We know replumbing the whole of Yorkshire is not a quick fix as it would be both significantly disruptive and costly to customers. The map shows just how big an engineering challenge this is from the vast numbers of overflows we have.”

He added Yorkshire Water was “investing £180m by the end of April 2025 to tackle 134 of the more frequently discharging overflows”.

The £180m investment is split into four areas, he added. They are: increasing storage at Yorkshire Water’s wastewater treatment works and within the sewage network; separating surface water from the combined sewer system; reducing groundwater infiltration into sewers; and changes to the operation of treatment works.

Two environmental groups have responded to the news of sewage spills more than doubling in the River Nidd and Ure last year.

It comes after the Environment Agency last week revealed sewage discharge figures for all water and sewage companies in England, including Yorkshire Water.

The Stray Ferret analysed the data for the two main rivers in the Harrogate district and found sewage spills not only more than doubled in 2023, but also saw a total of 27,838 hours of spills.

Investment into infrastructure ‘coming too late’

We contacted Nidd Action Group (NAG), which spearheads the iNidd campaign for improved water quality, about the recent figures.

The group appear less than impressed about the significant increases.

David Clayden, the chair, last week told the Stray Ferret:

“From NAG’s quick look at the Nidd data, there seems to be at least 30% more spills this year for almost double the hours of spilling sewage than last year.

“Bear in mind that Yorkshire Water’s plan, determined by the government, is to reduce the average number of spills per asset to less than 10 per year by 2050 (quicker for Knaresborough if we get Safe Bathing Water Status). Yorkshire Water’s considerable investment in infrastructure is coming too late and won’t get the safe bathing and ecological balance in our river right for many years.

“The numbers are going the wrong way. NAG is looking for reduction year-on-year — not upward blips!

“Of course, it has rained a lot this winter but we need to be prepared for changed weather patterns, not just hoping for the best.”

Mr Clayden said the group will “continue to scrutinise what is being planned and what is being achieved for the Nidd”.

NAG will also press Yorkshire Water and the Environment Agency for effective and rapid ways to reduce this tide of sewage, he added.

Rivers trust says figures are ‘distressing’

We also contacted the Yorkshire Dales Rivers Trust (YDRT), a charity that works to protect local rivers, about the data.

Charlotte Simons, catchment partnership manager for YDRT, said the figures come as “distressing news” to the organisation, adding:

“As our population grows and we experience more extreme weather events as a result of climate change, the frequency of these discharges will only increase, unless action is taken. We want to see an end to the practice of discharging raw sewage into our rivers.

“We want to be able to swim, paddle, fish and play in our rivers without risk of getting sick. We want to give our native wildlife a chance to recover, and see our rivers full of life.

“Yorkshire Water has pledged investment over the next five years to tackle this problem. Now we need the government to play their part and approve that spending, to hold Yorkshire Water to account, and to ensure that good decisions are made for long-term environmental and societal benefit.

“This means working with nature as much as possible, looking for integrated solutions that tackle the sewage problem along with other sources of pollution, and deliver more benefits to society too.”

The Stray Ferret reported on the Nidd and Ure statistics last week, which also recorded a total of 2,799 counted continuous spills between the rivers.

Political rivals Andrew Jones MP and Tom Gordon also shared their rather opposing views on the figures at the time.

• Sewage spills in Nidd and Ure more than doubled in 2023

Leading Harrogate and Knaresborough politicians have reacted to the news that sewage spills in the River Nidd and River Ure more than doubled last year.

The Environment Agency published sewage discharge figures for all the water and sewage companies yesterday. The Stray Ferret analysed the data to discover the amount of recorded incidents had more than doubled for the Nidd and Ure.

Water quality is likely to be a key issue at the next general election.

Andrew Jones, the Conservative MP for Harrogate and Knaresborough, has led a campaign to achieve bathing water status at Knaresborough Lido on the Nidd.

Tom Gordon, the Liberal Democrat parliamentary candidate for Harrogate and Knaresborough, has attacked the government for its record on pollution and called for a ban on water company directors’ bonuses.

The rivals gave different reactions to yesterday’s figures.

‘A complex picture’

Mr Jones told the Stray Ferret sewage “isn’t the only cause of pollution in rivers – particularly the Nidd”, adding run-off from farmlands also contributed to the issue.

Mr Jones said:

“The combined storm overflows are designed to discharge the contents of sewers into waterways when the sewers are blocked or overloaded.  In 2023 there was exceptionally heavy rainfall which meant the overflows operated more often, stopping sewage backing up into our properties. We need solutions that mean the storm overflows operate less and I am pleased that significant investment is happening and I am pushing for more.

“This shows the importance of a joint effort between water companies, the Environment Agency, house builders and many others to ensure that rainwater run-off into our sewer system is lessened through tree planting, on-site water storage on new estates and separation of clean water and wastewater sewage streams.

“Water quality is a complex picture and to tackle it we need to tackle all the underlying causes.  This underlines the importance of gaining bathing water status for the Nidd. This will mean a five-year plan is developed encompassing all the causes of pollution and engaging all partners in finding a solution.  That is what I have been championing with the local community and I hope to learn the outcome of our bid soon.”

‘A complete scandal’

Mr Gordon went on the front foot by attacking the Conservative’s record on pollution.

The party yesterday claimed the Conservative MPs have “consistently voted against measures which would have helped to tackle the crisis – including Andrew Jones”.

Mr Gordon told the Stray Ferret:

“It is a complete scandal that filthy sewage is being pumped into our River Nidd. Despite our Conservative MP claiming to be campaigning on sewage we have seen the total number of hours of sewage dumped into the Nidd skyrocket, more than doubling.

“It’s beggars belief that Conservative MPs have allowed water firms to get away with this environmental vandalism. Local people are furious that Conservative politicians blocked tougher action on these disgraced firms.

“Here in Harrogate and Knaresborough we have a Conservative MP who has consistently voted against measures to stop the sewage scandal, local residents deserve better. Local residents and our precious environment need actions not words.

“The Liberal Democrats are calling for tougher action to stop sewage being dumped in local rivers/beaches including replacing Ofwat with a regulator that has real teeth to clamp down on these polluting firms. We have also called for a ban on bonuses for water company fat cats whose firms have pumped filth into our waterways.”
