A conservationist has warned that Harrogate’s “creaking sewerage infrastructure” needs investment to cope with all the new homes.

Keith Wilkinson, who is chairman of Nidd Gorge Advisory Partnership and honorary secretary of Bilton Conservation Group, said more pollution was likely without improvements.

His comments come as investigations into last weekend’s pollution of Oak Beck are ongoing.

The Environment Agency, which previously said it was unable to comment during the Queen’s mourning period, gave a brief update today in which it said it had investigated “several” reports of dead fish and pollution and it was “identifying the source of what caused the fish deaths”.

Oak Beck, which rises at Haverah Park and empties into the River Nidd at Nidd Gorge, is classed as a main river by the Environment Agency even though it is narrow.

Mr Wilkinson said long-recognised problems with broken and wrongly connected Victorian pipes near The Hydro remained unresolved.

This, along with new housing developments in the area, would exacerbate the issue further, he said.

Mr Wilkinson said:

“North Harrogate’s sewerage system has been operating on optimum-to-overload capacity for at least a decade — before we see the aggravating grey water outputs of the excessive housing expansion on the A59 and Penny Pot Lane.

“In other words ‘we ain’t seen nothing yet’.”

Mr Wilkinson, who was awarded an MBE for services to conservation, also said he wasn’t aware of any plans to develop the northern outfall sewage works at Bilton to cope with the anticipated increase of sewage caused by new homes. He added:

“Their site has many spare acres of unused land — it occupies 56 acres in total — but I detect no suggestion that there will be significant investment in new infrastructure to increase its capacity to receive and process more inputs.”

Oak Beck fish deaths still a mystery

Contaminated water on Oak Beck stretched from The Hydro to Bilton this week. Mr Wilkinson said the watercourse would take three years to recover.

A Yorkshire Water spokesman said yesterday it was “still on site, trying to investigate possible sources” of the contamination. He added initial tests had shown the cause was not sewage.

Northern Gas Networks said the pollution is unconnected to work it is carrying out on the site earmarked for a new Tesco.

Mark Johnson, senior project manager at NGN, said:

“We’re currently undertaking work to safely dismantle the gas holder on Skipton Road and all of our discharge takes place into the main sewerage system, as is required.

“Following reports of a possible contamination at Oak Beck, we’ve been liaising closely with the Environment Agency and Yorkshire Water, both of whom have confirmed that there is no connection with our work. We will continue to monitor the situation closely.”

A leading Harrogate conservationist has said Oak Beck will take three years to recover from this week’s pollution.

Hundreds of fish are believed to have died when the water turned brown over the weekend. The cause is unknown.

Keith Wilkinson has called on Yorkshire Water and the Environment Agency to join efforts to prevent further pollutions in the beck, which he said occur too frequently.

He said:

“Pollution events along the Oak Beck — which is classed as a ‘main river’ by the Environment Agency — destroy wildlife and have implications for public health.

“As chairman of the Nidd Gorge Advisory Partnership I would like to invite representatives from the EA and Yorkshire Water to join the partnership and coordinate efforts to eliminate illegal discharges along the Oak Beck and the River Nidd.

“One toxic spill such as that experienced on 10th September sets back all our conservation efforts for at least three years.”

Oak Beck rises at Haverah Park and empties into the River Nidd at Nidd Gorge.

Dead fish were first spotted in the watercourse at Oak Beck retail park this morning.

The discolouration appears to have affected the stretch from the Hydro to the far side of Knox Lane.

The Stray Ferret met Mr Wilkinson, who is also honorary secretary of Bilton Conservation Group, at Spruisty Bridge on Knox Lane today.

Several residents told us they were concerned about the pollution and how seriously it was being investigated.

One person said dog walkers had been keeping their pets on leads to prevent them entering the water. There have also been reports of dead ducks but none were evident during our visit.

Harmful discharges

Mr Wilkinson said a good year for spawning fish on the beck had been ruined.

He said water quality often suffered from the impact of the number of new homes built, as well as harmful discharges entering the drains.

The beck contains brown trout up to several inches long, as well as minnows, bullhead, stone loach and sticklebacks.

Mr Wilkinson said invertebrates on the bed of the beck were also killed and their numbers needed to recover before fish levels could return to normal.

He added that kingfishers and otters had kept away from the river since the incident.

An Environment Agency spokeswoman said yesterday she was unable to comment on what, if any, action it had taken because it was not responding to media inquiries about non life-threatening incidents during the Queen’s mourning period.

A Yorkshire Water spokesperson said yesterday:

“Our teams, along with the Environment Agency, have conducted initial investigations after reports of a pollution at Oak Beck over the weekend.

“Our tests have indicated the substance entering the beck is not sewage. We are continuing to investigate and will also be visiting local businesses to try and trace the source.”

Hundreds of fish are believed to have died in a pollution incident at Oak Beck, Harrogate.

The cause of the incident, which occurred at Oak Beck Park, close to the retail park, is not yet known.

A Yorkshire Water spokesperson said:

“Our teams, along with the Environment Agency, have conducted initial investigations after reports of a pollution at Oak Beck over the weekend.

“Our tests have indicated the substance entering the beck is not sewage. We are continuing to investigate and will also be visiting local businesses to try and trace the source.”

The beck flows into the River Nidd.

Councillor Paul Haslam, who represents Harrogate Old Bilton on Harrogate Borough Council and Bilton and Nidd Gorge on North Yorkshire County Council, informed Yorkshire Water of the incident after being notified by a resident yesterday.

Cllr Haslam posted some images, which we have published, that were sent to him by the resident.

They show fish floating on the surface and the water looking extremely brown.

Cllr Haslam said the only way to get over the seriousness and upsetting nature of what had happened was to quote the person who reported it, who said:

Residents in Harrogate’s Kingsley ward say construction traffic has left them worrying about harmful dust and air pollution — but a “weak” Harrogate Borough Council has done little to clamp down on developers. 

Over 700 homes will eventually be built in the ward by five different developers but Kingsley Road and Kingsley Drive are accessed off the busy Knaresborough Road.

This has led to lorries and trucks driving through residential roads to get to the building sites.

Residents say the construction traffic has resulted in vast amounts of dust and dirt from lorries ending up on roads, cars and houses. They say it’s so bad they worry they’ll have to wear masks to protect themselves.

Gary Tremble, from Kingsley Ward Action Group (KWAG), said:

“We have complained for over three years yet to this day the wagons travel down our residential street spewing out dust in summer and dirt in winter, we now even have fully laden uncovered wagons taking dirt into the developments.”

Mr Tremble believes the dust is made up of PM10, an air pollutant typically seen on building sites. When breathed in, it can penetrate deep into the lungs.

Exposure to high concentrations of PM10 has been linked by scientists to asthma attacks, high blood pressure, heart attacks and strokes.

‘We’ve been ignored’

When a development receives planning permission from HBC, conditions are attached that stipulate how housebuilders will minimise the impact of issues including dirt and dust.

This sometimes involves making sure there are onsite wheel cleaners and covering wagons that are carrying materials or waste.

Mr Tremble added:

“We’ve made hundreds of complaints to Harrogate Borough Council but enforcement but are weak. They don’t do anything and we’ve been ignored.”

The issue of how effective the council’s planning enforcement team was raised at a council meeting this week.

Conservative councillor for Old Bilton, Paul Haslam, said he and other councillors had received complaints from KWAG accusing the council’s planning enforcement team of not ensuring that conditions were being upheld.

Conservative councillor for the Washburn ward, Victoria Oldham, asked Cllr Haslam if he thought HBC’s planning enforcement team was acting on complaints from residents “in a timeous manner”.

Cllr Haslam said he was concerned that enforcement officers “don’t have enough support”. He said:

“Quite clearly, guidelines are being flaunted [sic] by the developers. We need to make sure we are seen to protect our residents.”

‘Addressing the concerns’

In response to KWAG, a Harrogate Borough Council spokesperson said:

“We are aware of concerns relating to dust from HGVs entering and exiting the development(s) on Kingsley Road and have allocated a case officer to address these concerns.

“We have discussed the matter with the county council and the developer and have reminded them of actions they must maintain as per the conditions of the planning permission.

“These actions have been actioned – as well as some further recommendation, including road sweeping – by the developer and we will continue to closely assess this situation to ensure they continue to do so.”

The Environment Agency and Yorkshire Water are being called upon to investigate a foaming discharge into the River Ure in Ripon.

There are fears the discharge could be potentially harmful to humans, aquatic life and water fowl.

The Stray Ferret contacted the EA incident line after seeing the discharge yesterday and understands that the stretch of river near the Duchess of Kent Bridge on the A61 Ripon bypass has been affected since the weekend.

James Thornborough, an internationally-recognised authority on spillage on land and water, reported the incident to YW and said it would be normal practice for them to share the information with the EA.

The expert, who lives in nearby Sharow, told the Stray Ferret:

“I pass this part of river, which can be seen from the Dishforth Road, on a regular basis and on Sunday noticed the foaming on the water coming from a drainage outlet that feeds into the Ure.

“In my opinion this is not normal occurrence for this part of the river and that is why I reported it.

“It certainly warrants scrutiny by the EA to find out what exactly is being discharged and whether it is benign or potential harmful to people and animals.

“If it is discovered to be harmful, urgent remedial action will need to be taken.”

The drainage outlet (top right on the photograph) has been the source of the white foaming substance.

Mr Thornborough added:

“The EA, as the national competent authority for protecting the natural environment of the UK, is bound to assess any reported pollution incident and I would urge anybody who witnesses something like this, that looks out of place, to report it as soon as possible.

“Rivers collect water naturally from the atmosphere (rainfall), surface drainage (run off), ground waters, and underground aquifers.

“Unfortunately rivers must also cope with Industrial waste. Controlled industrial discharges are subject to license conditions. Uncontrolled industrial discharges occur due to operating controls failures, accidents or deliberate intention (criminal behaviour).”

What can the Environment Agency do?

Mr Thornborough said he expected the EA to analyse water samples. He added:

“Industrial pollution can reduce the concentration of bio dissolved oxygen in the water phase which can cause fish kills.

“At the very least, the biodiversity of the River Ure in the surrounds of this foaming event, has likely been impacted and microscopic marine organisms will have been killed upsetting the food chain.

“With this in mind, all stakeholders – from business operators, to  the public and compliance organisations such as the EA, have a role to play in ensuring that our precious water resources are safeguarded.”

Harrogate and Knaresborough Liberal Democrats have called on the government to introduce a sewage tax to raise money to clean rivers.

The party said a 16% tax on water companies would help to create an emergency fund to improve rivers which had sewage dumped into them.

The Stray Ferret reported in November that Yorkshire Water released raw and untreated sewage into Harrogate district rivers and becks on 3,800 different occasions in 2020.

The worst affected local river is the River Nidd, prompting health concerns from wild swimmers that use the river in Knaresborough.

Water companies are legally allowed to release sewage through overflow pipes when the sewage system becomes too full, which can happen during increased rainfall.

• Raw sewage released into Harrogate district rivers for 36,000 hours last year

The Liberal Democrats highlighted that Yorkshire Water made an operating profit of £241 million last year.

Hannah Gostlow, the Liberal Democrat councillor for Scriven Park in Knaresborough, said:

“Rivers should be safe for sustaining wildlife, swimming and leisure. They are a precious source of drinking water for some. 

“So why are they filled with raw sewage and human waste, destroying them for decades to come?

“It is disgraceful to see a company which pollutes our local rivers with sewage make so much money last year. I think Yorkshire Water should pay to clean up the mess they make here. This Conservative government is once again too slow to act and doing nothing to protect our local rivers.”

The Stray Ferret contacted the Conservative leader of Harrogate Borough Council, Cllr Richard Cooper, to ask for his response to the proposal. He referred us to the council press office. We await a response.

Western Primary School installed a pollution sensor in June last year, amid concerns about heavy traffic on Harrogate’s Cold Bath Road.

Headteacher Tim Broad was worried about the sheer volume of traffic plus the fact he could tase diesel in his mouth when larger vehicles passed.

Six months on, The Stray Ferret has reviewed the data, which suggests levels of pollutants meet national objectives but exceed guidelines set by the World Health Organisation.

The sensor, which was installed within the school grounds, revealed concentrations of PM2.5, PM10 and nitrogen dioxide (NO2) all fell within the national objectives’ limits for short and long-term exposure.

However, a local pollution campaigner expressed concern that PM2.5 and NO2 levels exceeded WHO guidelines both short- and long-term.

PM2.5 particles are man-made particles suspended in the air, produced by woodburning stoves and transport, as well as industrial processes. When breathed in, these particles can get into the blood and lodge themselves in organs.

NO2 is a gas produced by combustion of fossil fuels. Eighty percent of roadside NO2 pollution is caused by road vehicles. Exposure to the gas can cause inflammation to the airways and exacerbate pre-existing heart and lung conditions.

‘No safe threshold for air pollution’

We showed our findings to Western headteacher Tim Broad, who said he was “concerned” by the exceedance of WHO guidelines, Mr Broad added:

“I intend to follow up with an investigation in school, with a view to passing on the findings to the appropriate people at Harrogate Borough Council and North Yorkshire County Council.”

Local campaigner Brian McHugh claimed the national objectives were too weak, and children were at risk. He added:

“The concern with using numbers and limits sometimes can be that there is a belief formed that anything up to that level is ‘safe’. There is no safe threshold for air pollution.

“The harm of air pollution on humans is well documented. The increased harm to children, with developing lungs, cannot be overstated.”

Better monitoring needed

Western Primary School is believed to be the only school in the district with an air pollution sensor, and live measurements from the sensor are available to the public online here.

Mr McHugh called for better monitoring of pollution in and around schools. He said:

“It is incredibly useful that we are even able to have this data and analyse it. Huge thanks must go to Western Primary for having the foresight to install an air quality sensor and it is hoped that other schools in the Harrogate district follow their example, so we have accurate information on which to base policies and initiatives.”

In its 2021 Air Quality Annual Status Report, Harrogate Borough Council used 63 monitors throughout the district to measure NO2 levels but had no monitors for PM2.5 particles.

The council itself stated PM2.5 can have a significant impact on health, including “premature mortality, allergic reactions, and cardiovascular diseases”, but it relied on council data from Leeds and York to estimate levels of the pollutant in the district.

Yorkshire Water says it is investigating an unusual incident where bubbles filled a section of Hookstone Beck today.

Two Stray Ferret readers contacted us with photos of the beck this morning when what appeared to be a sea of washing-up liquid bubbles appeared on the surface.

Andrew Mann said he was out for a walk near the Yorkshire Event Centre when he noticed “something clearly had gone wrong”.

He said bubbles had risen 10-feet-high and raised concerns about any fish that might be swimming in the beck, which feeds into Crimple Beck.

A spokesman for Yorkshire Water said the incident was not related to sewage pollution. He suspected somebody had poured detergent down a drain that is intended for rainwater and runs off into the beck.

An investigation is underway to find the source of the problem and whether the substance is harmful to wildlife. Yorkshire Water will then share its findings with the Environment Agency.

Wild swimming has become more popular in recent years among people who prefer swimming in rivers and lakes than inside buildings.

Knaresborough woman Miranda Newbery is among those who have taken up the sport. She started last year during lockdown and says feeling connected to nature whilst exercising gives a sense of freedom and changed her life.

Ms Newbery currently swims in the River Nidd with friends once or twice a week but says pollution levels have become an increasing concern.

Last summer she introduced her children to wild swimming. They later fell ill and although she cannot be sure it was due to pollution she has since bought them snorkel-like masks to wear.

She said:

“It makes me nervous, of course I couldn’t prove it was because of the water but it gives us all so much pleasure I don’t want to stop the kids doing it.

“The river is key to Knaresborough and used by so many. It is something we should look after with our politicians working to protect it too.”

The state of rivers has been a hot topic since MPs voted last month against an amendment to stop water companies, such as Yorkshire Water, pumping raw sewage into British rivers.

Andrew Jones, the Conservative MP for Harrogate and Knaresborough was among those who voted against the amendment. He later said he would support a new amendment to the Environment Bill that would reduce sewage in waterways.

Failed pollution tests in Nidd

The Stray Ferret spoke to other local residents last week who echoed Ms Newbery’s views and called for action to reduce pollution in local rivers.

Jacqui Renton, from Knaresborough, who swims in the Nidd as part of her training for a British championships open water swimming competition, said the Nidd had failed water pollution tests and was “a potential health risk”.

Nevertheless the swimmers plan to keep plunging into the Nidd.

Ms Newbery says she’s shared laughter and heartbreak with other wild swimmers over the last year and encourages people to give it a go.

“There is something about the combination of the cold water and being in the beautiful natural surroundings that we are blessed with in Knaresborough that is truly restorative.”

“It’s a mindful practice and sharing that with friends is so special.”

Residents have said MPs voting against an amendment to stop raw sewage being pumped into rivers have created a “potential health risk” in the River Nidd.

Last week, MPs voted 268 to 204 against the Lords amendment, which means water companies such as Yorkshire Water can continue pumping raw sewage into British rivers.

Andrew Jones, the Conservative MP for Harrogate and Knaresborough was among those voting against the amendment.

Last year, every section of the Nidd that runs through the Harrogate district failed water pollution tests due to wastewater contamination – including raw sewage.

The Nidd is used for recreation by families, swimmers and even competitors in Knaresborough Bed Race. Some have expressed disappointment at the MPs’ vote.

Jacqui Renton, from Knaresborough, who swims in the Nidd as part of her training for a British championships open water swimming competition, said:

“Last year the River Nidd failed water pollution tests due to the river being contaminated with wastewater. This included raw sewage, making swimming in it a potential health risk.

“More worryingly, raw sewage being discharged into our rivers of course has a bigger consequence for wildlife, threatening the biodiversity and ecosystem health, which is why urgent action is needed.”

A section of the river in Knaresborough is also used by competitors in the annual bed race. Kevin Lloyd, chairman of the bed race committee, urged Yorkshire Water to stop pumping sewage into the river on the day of the event.

However, Mr Lloyd said more action was needed:

“Any initiative that protects the environment is a good thing so I am disappointed at this defeat.

“Yorkshire Water are sympathetic to the event and do what they can but there’s always more that can be done to protect the environment.”

Nidd a ‘huge leisure attraction’

Cllr Hannah Gostlow, a Liberal Democrat who represents Knaresborough Scriven Park on Harrogate Borough Council, also raised concerns as a councillor and local resident.

She said the Nidd was a “huge leisure attraction” used by paddle boarders and young children.

She added:

“The River Nidd is already polluted with wastewater, including with raw sewage, and failed recent pollution tests. The government should be stopping sewage going into our rivers full stop.”

The Stray Ferret contacted Mr Jones about the issue but he declined to reply.

However, he said on his Community News website that he would support a new amendment to the government’s Environment Bill providing a costed plan to reduce sewage in our waterways. He said:

“It would not be sensible to support such a complicated change without having a costed plan. This is what the Lords amendment lacked and why I did not support it.”
