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 in Nidd and Ure: local politicians react to increase
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.”

Sewage spills in Nidd and Ure more than doubled in 2023
The Environment Agency has published its annual storm overflow spill data for 2023 – and the two main rivers in the Harrogate district saw significant increases.
The agency today released its event duration monitoring data, which shows the frequency and duration of sewage spills as a result of storm overflows in England.
It includes data from the nation’s 10 water and sewage companies, including Yorkshire Water.
Yorkshire Water recorded the second highest number of storm overflow spills. Its 77,761 figure was surpassed only by United Utilities, which released sewage on 97,537 occasions.
The Stray Ferret has been looking at the data for storm overflows that affect the River Nidd and the River Ure.
The Nidd flows through Pateley Bridge and Knaresborough and its tributaries, such as Crimple Beck and Oak Beck, run through Harrogate.
The Ure flows through Masham, Ripon and Boroughbridge.
Nidd and Ure data
The Nidd saw a total of 16,226 hours of sewage spills in 2023, which is a 120% increase from the year prior (7,380 hours).
The data also shows the total number of spills using the Environment Agency’s 12-to 24-hour count method, which records spills according to their duration.
Any discharge in the first 12-hour block is counted as one spill. Any discharge in the next 24-hour blocks are each counted as one additional spill.
This method is used to ensure very long, continuous spills over multiple days are not counted as one spill.
Using this method, the number of counted spills in the Nidd in 2023 was 1,561, compared with 1,010 in 2022 (a 55% increase).
The Ure saw a mammoth 11,612 hours of sewage spills in 2023 – a 166% increase from 2022’s 4,370 hours.
Using the 12-to-24-hour count method, the Environment Agency recorded a total of 1,238 spills in the Ure in 2023, compared to 880 in 2022.
Yorkshire Water ‘disappointed’ by figures
We contacted Yorkshire Water for comment on the number of spills.
A spokesperson for the firm said it was “disappointed about the number of discharges in 2023”.
They added:
“This increase is due to the wet weather experienced in the 12-month period, which included 11 named storms. The weather experienced in the region in 2023 included a very wet summer and prolonged heavy rainfall towards the end of the year resulting in groundwater infiltration into the sewer network.
“Overflows operate during prolonged or heavy rainfall and multiple storms in close succession can lead to increased discharges due to the storm capacity being used up.
“Our teams worked hard throughout 2023 to reduce discharges as part of our commitment to improve the operation of our network. As a result, our modelling indicates investment in our network and changes to our operations since 2021 equate to an improvement of 12,980 discharges when normalised against rainfall.”
The spokesperson added Yorkshire Water was “making headway” with a £180 million programme to reduce discharges across the region by April 2025.
They continued:
“Work is in progress on 62 projects, including some on the Nidd and Ure, that will reduce discharges from some of the most frequently operating overflows, with more to follow later in the year.”
National picture
The Environment Agency revealed a 54% increase in the total number of sewage spills in 2023 compared to the year prior, and said there were 14,318 storm overflows during the calendar year — up from 13,313 in 2022.
A total of 100% of storm overflow networks are now fitted with event duration monitors in line with the government target, the agency added, which enables it to collect data.
Helen Wakeham, director of water at the agency, said:
“Whilst it is disappointing that water companies have reported an increase in sewage spills in 2023, it is sadly not surprising. We are pleased to see record investment from the water sector, but we know it will take time for this to be reflected in spill data – it is a complex issue that won’t be solved overnight.
“No other country has the level of monitoring we do, with 100% of storm overflows in England now fitted with a monitor. We are better placed than ever before to hold water companies accountable.”

Knaresborough duck race cancelled due to high river level
Knaresborough’s traditional New Year’s Day duck race will be held online for the second consecutive year due to high river level.
Knaresborough Cricket Club, which organises the event, posted on social media today that it had acted on safety grounds.
It said the event will instead take place virtually rather than by releasing toy ducks off High Bridge on the River Nidd.
The club said:
“It is with a heavy heart that we need to tell you all that the duck race has been cancelled on New Year’s Day 2024 due to safety reasons.
“The river is very high, and with rain last night and heavy showers forecast our partners on the river think that the river will be much too high to have boats in the river and it will be unsafe for all.
“Thanks to all that have purchase tickets. The race will GO AHEAD ONLINE. A link will be posted on here. The race will start at 2.30pm, or why not join us in person at Knaresborough Cricket Club from 2pm.”
It added that all prized will be delivered and funds will go to the club’s junior cricket section and local disability charity Henshaws.
After a wet few weeks, Environment Agency flood alerts remain in place for the Lower River Ure and the River Nidd at Hunsingore in the Harrogate district.
The latest update for the Ure this morning said:
“Areas most at risk include low-lying land, including agricultural land, and local roads in the areas around Boroughbridge, Aldborough, Bishop Monkton and Aldwark.”

Village floods as Harrogate district warnings remain
Eight flood alerts and warnings remain in place across the Harrogate district this morning after hours of persistent rain.
Many roads and large swathes of land were flooded last night, leading to treacherous conditions.
Last night also saw firefighters deployed sandbags at Killinghall Primary School after some of the building was flooded.
Driving on the A61 between Harrogate and Ripon was particularly dicey, with the bridge dividing Ripley and Killinghall deep in water.
Bishop Monkton, which is between the two locations, was among the worst hit areas as the beck flooded.

Bishop Monkton is subject to a flood warning, which was updated by the Environment Agency at 1.30am this morning to say further rainfall is forecast this afternoon and over the weekend.
It added:
“We are monitoring rainfall and river levels and are checking rivers for blockages in the area. Plan driving routes to avoid low lying roads near rivers which may be flooded.”
Flood warnings, which are more severe than flood alerts because they indicate flooding is expected and people should act, are also in place on the River Ure at Boroughbridge camping and caravanning site and on the River Nidd at Hunsingore, which is between Cattal and Kirk Deighton.
The Hunsingore warning, updated at 2.20am this morning, says:
“Areas most at risk include The Old Cornmill at Hunsingore. Further rainfall is forecast over the weekend. We will continue to monitor levels closely. Residents are strongly urged to take action now. Remain safe and be aware of your surroundings.”
The Boroughbridge warning says:
“River levels are expected to remain high into the weekend, where further heavy showers are possible. We are closing locks and flood gates in the area.”
Less severe flood alerts are active on the Lower River Ure, the Upper River Nidd catchment area, the Middle River Nidd catchment area, the Lower River Nidd catchment area River Crimple.
Rain died out overnight but the wet weather is forecast to return this afternoon and tomorrow.

River Nidd clean-up campaign boosted by £500,000 from Yorkshire Water
A campaign to clean-up the River Nidd has received a £500,000 boost — from a penalty paid by Yorkshire Water for polluting Harrogate..
Yorkshire Water revealed last week it had agreed to give £1 million to charities for polluting Hookstone Beck in Harrogate.
The sum — to atone for an unauthorised sewage discharge that killed fish in the beck — was divided equally between Yorkshire Wildlife Trust and Yorkshire Dales Rivers Trust.
A meeting in Knaresborough yesterday heard Yorkshire Dales Rivers Trust, which is based in Pateley Bridge, will use the funding to lead the iNidd project to clean-up the River Nidd.
Charlotte Simons, senior project manager at the trust, told the meeting:
“The sad thing is we have the money because something went wrong.
“But we have been given a lump sum that can lead to long-term improvements on the River Nidd.”

Yesterday’s meeting in Knaresborough.
The trust, which runs improvement projects across the catchments of the Swale, Ure, Nidd, Wharfe and Ouse, will work with anglers, academics and wild swimmers as well as Yorkshire Water and the Environment Agency on the iNidd scheme.
Andrew Jones, the Conservative MP for Harrogate and Knaresborough, is also involved through his campaign to achieve bathing water status on the Nidd at Knaresborough Lido.
The trust previously led the iWharfe project to improve the River Wharfe.
Yorkshire Water’s iNidd funding will pay for water quality schemes and other initiatives, such as habitat improvements and tackling invasive non-native species.
Nidd Action Group organised yesterday’s meeting at the Centre on Gracious Street, which gave members of the public the chance to quiz those involved in the iNidd campaign.
It followed a previous meeting at the same venue in spring this year, which marked the start of the clean-up campaign.
David Clayden, chair of the action group, said:
“We have achieved a lot in six months. I expect to see plans come together in the next six months that are collaborative and will make a difference.”

Yorkshire Water’s £1m pay-out to charities branded ‘pathetic’
News of Yorkshire Water’s record £1 million payout to environmental charities to atone for polluting Hookstone Beck in Harrogate has met with mixed reactions, with one local politician branding it “pathetic”.
As we reported yesterday, the utility company polluted Hookstone Beck in 2016 with an unauthorised sewage discharge, killing fish and breaching its environmental permit.
Following an investigation, it offered the Environment Agency an Enforcement Undertaking to pay £500,000 to Yorkshire Wildlife Trust and £500,000 to Yorkshire Dales Rivers Trust. The Agency accepted the undertaking, making it the largest civil sanction it has ever accepted.
Yorkshire Water has also completed a £1.85 million sewer network upgrade in the area as part of the enforcement terms.
But Tom Gordon, parliamentary candidate for the Liberal Democrats, slammed the agreement. He said:
“This is a pathetic pay-out for a firm which raked in over £500 million in profit last year. Conservative Ministers need to get tough on this polluting firm and fine them far more, as well as ban their insulting bonuses.
“It is a scandal that Yorkshire Water’s exec bonuses are more than double the amount offered for killing animals and destroying rivers in Harrogate.
“This reeks of a pathetic bribe, which Ministers have fallen for – hook, line and sinker.”

- Harrogate Lib Dems criticise Yorkshire Water £2m executive payments
Mr Gordon’s adversary, Harrogate and Knaresborough MP Andrew Jones, who is a colleague of the Ministers referred to by Mr Gordon, was more phlegmatic. He said:
“This is a significant sum in respect of an incident over seven years ago. These incidents should not happen and I am aware through my regular contact with Yorkshire Water on water-quality issues that substantial investment has been made since this event.
“The fact that such a large penalty has been paid by Yorkshire Water shows the seriousness with which the government takes pollution. I am pleased to see that the money is being spent locally – importantly on improvements to the River Nidd catchment and at Staveley Nature Reserve to support wildlife habitats.”

Volunteers from Nidd Action Group sampled water quality in rivers and becks across the district over the summer.
Meanwhile, Nidd Action Group (NAG), which was set up in Knaresborough in 2022 to stop sewage pollution and make local rivers safer, said it was disappointed the deal had taken seven years to strike, but hoped it would serve to change water companies’ behaviour.
David Clayden, chairperson of Nidd Action Group, said:
Yorkshire Water pays record £1m to charities after polluting Harrogate beck“NAG deplores the huge amount of sewage (treated and untreated) that continues to enter the river Nidd, often via becks that meander through parts of Harrogate and Knaresborough (2,000 spills and 12,000 hours in 2022, according to the latest data available).
“NAG’s recent two citizen science surveys, in August and October, have confirmed continuing high levels of E. coli bacteria and phosphates in parts of the Nidd Catchment, including many becks.
“One of our sampling points was on Hookstone Beck, and our surveys this year showed high concentrations of both forms of pollution, causing risk to human life and to the ecology in and around the becks, even after extensive work has been carried out.”
“NAG is disappointed that resolution of these incidents has taken so long, but hopes that this ‘charitable donation’ acts as a meaningful deterrent to the neglect of our rivers and results in significant improvement of our becks for the healthy enjoyment of these formerly attractive local assets.
“NAG looks forward to working with The Environment Agency and with Yorkshire Water to review the current evidence gathered by local citizen scientists and to ensure much needed improvements in the Nidd Catchment.”
Yorkshire Water has paid a record £1 million to environmental and wildlife charities after polluting a Harrogate river, following an investigation by the Environment Agency.
The utility company polluted Hookstone Beck with an unauthorised sewage discharge from Hookstone Road combined sewer overflow, killing fish and breaching its environmental permit.
It submitted an Enforcement Undertaking to the Environment Agency, proposing a charitable donation totalling £1 million, which is the largest ever accepted by the Agency.
It has paid £500,000 to Yorkshire Wildlife Trust and £500,000 to Yorkshire Dales Rivers Trust. It has also completed a significant £1.85 million sewer network upgrade in the area as part of the enforcement terms.
Claire Barrow, Environment Agency area environment manager in Yorkshire, said:
“We always consider enforcement options on a case-by-case basis and Enforcement Undertakings allow companies to put right what went wrong and contribute to environmental improvements and outcomes.
“This significant £1 million civil sanction will be invested back into the local area to enhance the environment for people and wildlife.
“The Environment Agency investigation also led to significant improvements to the sewer network in this area to prevent repeat incidents and ensure future compliance with environmental requirements.”

The Stray Ferret has extensively covered this issue. As we reported in July 2023, it agreed to pay £235,000 to Yorkshire Wildlife Trust following an illegal discharge into Hookstone Beck in 2015. Two years ago, we also reported on a “sea of bubbles” that appeared in the beck.
And the problems are not confined to that particular watercourse. Earlier this year, the Stray Ferret revealed that Yorkshire Water had discharged sewage into the River Nidd 870 times in 2022, and levels of the harmful bacteria E. coli are “concerningly high”.

An Enforcement Undertaking is a voluntary offer made by companies or individuals to make amends for their offending, and usually includes a payment to an environmental charity to carry out environmental improvements in the local area.
Hookstone Road combined sewer overflow has an environmental permit which allows a discharge into the beck when the storm sewage facility is full due to rainfall or snow melt.
On August 31, 2016 the Environment Agency received a report of pollution in Hookstone Beck. Investigating officers traced it to the overflow at Hookstone Road, which had blocked and not alerted Yorkshire Water due to faulty telemetry equipment.
The investigation found that almost 1,500 fish had been killed and water quality affected for 2.5km downstream. A series of further blockages and discharges took place in the following months.
A detailed Environment Agency investigation was undertaken, this included the use of devices called sondes in the river to measure the impact of ammonia and an assessment of Event Duration Monitoring data that revealed the company was in breach of its environmental permit.
As part of the Enforcement Undertaking requirements Yorkshire Water has already carried out a significant £1.85 million improvement and rebuilding project to the overflow and surrounding sewer network to bring it back into compliance with its environmental permit.

A spokesperson for Yorkshire Water said:
“This incident was initially caused by a plank of wood that shouldn’t have been in the sewer network and took place seven years ago. We acted quickly to stop the pollution but understand incidents of this kind are distressing and when things go wrong, we understand we have a responsibility to make it right and to prevent these things from happening at all.
“Unfortunately, it has taken seven years to reach an agreement with the Environment Agency to donate funds to local wildlife charities that will directly benefit Yorkshire, but we are pleased to have finally provided funds to the Yorkshire Wildlife Trust and Yorkshire Dales Rivers Trust.
“We’re committed to protecting the environment and our procedures and processes have evolved significantly since 2016, contributing to a halving of pollution incidents in the last five years. Following this incident in 2016, we spent almost £2 million to improve the sewer network in the area to prevent repeat issues.”
Individuals and organisations that pollute the environment will soon face unlimited penalties under new legislation being brought forward by the government. The current limit of variable monetary penalties that the Environment Agency can impose directly on operators will be lifted, following a government consultation which received widespread public support.
This will offer regulators a more efficient method of enforcement than lengthy and costly criminal prosecutions, although the most serious cases will continue to be taken through criminal proceedings.
Water Minister Robbie Moore said:
“This record penalty paid by Yorkshire Water demonstrates that those who damage our natural environment will be held to account.
“Our Plan for Water is all about delivering more investment, stronger regulation and tougher enforcement right across the water sector – and this penalty for Yorkshire Water demonstrates that we will take robust action when required.
“Our Plan includes scrapping the cap on civil penalties by introducing unlimited fines and significantly broadening their scope to target a much wider range of offences – from breaches of storm overflow permits to the reckless disposal of hazardous waste.”
Yorkshire Wildlife Trust will use the payment in North Yorkshire for new and improved homes for wildlife, mainly on their wetland reserves. This includes reprofiling Ripon City Wetlands to create muddy shores for wading birds, safe breeding islands and removing invasive plants, as well as replacing equipment. Habitat improvements on the River Tutt at Staveley nature reserve will also help to store flood water, protecting communities downstream.
Yorkshire Dales Rivers Trust will use the payment to develop a programme of improvements along the River Nidd. It will be working through the catchment partnership – Dales to Vales Rivers Network – with local communities and other organisations to build on existing work with citizen scientists.
Glut of housebuilding in Harrogate worsening Nidd raw sewage problemA massive increase in housebuilding across Harrogate and Knaresborough is worsening pollution in the River Nidd, according to the Environment Agency.
Jamie Duncan, who has worked on the Nidd for 20 years for the public body, gave a wide-ranging presentation about the health of the river to Harrogate and Knaresborough councillors earlier today.
Yorkshire Water is allowed to release sewage into the Nidd when the sewerage system is at risk of being overwhelmed through what are called storm overflows.
It has led to human waste being released over thousands of hours, and sampling by the Nidd Action Group has reported that the bacteria E. coli is at “concerningly high” levels.
Mr Duncan’s message to councillors was stark as he warned the problem could get worse without a recognition of the impact that development is having, and improvements to the town’s creaking Victorian sewerage system.
He said the Environment Agency was trying to tackle historic pollution problems, such as peat bog erosion and metal mining, which wash into the river at Nidderdale and travel downstream.
But he said its attempts are being made more difficult due to the thousands of new homes that have been built in the outskirts of Harrogate over the last decade — and thousands are more planned.
He said:
“If you are building housing estates on the urban fringe, on greenfield sites that historically have sewers just for servicing a pub and a few farms… and you’re putting hundreds of houses into these pipes then you only need a very small amount of rain [for waste] to spill into rivers.
“That’s untreated sewage. You’ve sieved out contraception and sanitary products, nothing more.”

During the 2010s the now defunct Harrogate Borough Council did not have a local plan for several years, which gave the authority little control over where developers chose to build.
Harrogate now has a local plan but Mr Duncan said North Yorkshire Council must give more consideration into what impact new housing is having on the sewerage system, which he said is struggling to cope.
He added that the situation is leading to more storm overflows and more sewage being pumped into the Nidd.
A working group of councillors was set up last year to tackle pollution in the river, following an incident last summer where several children ended up in hospital after swimming there.
A campaign is also underway to clean up the river so it can be designated with bathing water status. Harrogate and Knaresborough Conservative MP Andrew Jones submitted an application to government last month.
North Yorkshire Council is also in the early stages of developing a new county-wide local plan that will set out where housebuilding can take place over the next 15 years.
Paul Haslam, Conservative councillor for Bilton and Nidd Gorge, said he hoped the council can view the sewage network as a “critical part” of infrastructure, like roads.
In the meantime, Mr Duncan urged councillors to factor in the sewerage system when granting planning permission for new developments.
He said:
“If you’re going to grant it, please understand the knock-on effects. Houses might be new, but the sewage pipes might run a very long way through central Harrogate to a very old system that’s at capacity.”
