Sewage pollution: Citizen eco-warriors armed with budget shed tech patrol whiffy river frontline
What can you do with varnish, plywood, a wheelbarrow inner tube and a solar panel not much bigger than a mobile phone?
The answer, if you are a computer genius with a conscience, is to fight back against sewage pollution.
John Clifford has created an early warning system.
He said: “When pollution spikes, if it goes up more than 10%, we know that something’s gone on in the river.
“When several sensors all at once that are telling us the same thing, then we know that there’s a big problem.
“The app on my phone will update regularly and quite often.
“It’s the first thing I check in the morning.”
Mr Clifford lives in west London and the kit will float on the River Brent which, like so many of our rivers, is regularly polluted.
Alongside colleagues he’s making at least 30 of these sensors which measure what’s called TDS or total dissolvable solids – shorthand for faeces, food waste and soap residue.
They send data on the level of these unwanted ingredients in real time to an app, but despite that sophistication they are cheap.
The floating gadgets, which are able to monitor pollution levels around the clock, are cheap
At around £100 per sensor they are a fraction of the cost of professional kit which typically can cost £6,000.
The team behind the tech, CURB (Clean Up River Brent), got together after local resident Ben Morris was outraged by an incident in 2021, which turned the river grey with sewage sludge bordered by soapy white residue and was very smelly.
They began with campaigning and clean ups, but he feels their gadgets will make the biggest difference.

Mr Morris said: “Once you know what’s in the river, you can then start to have a conversation about what should be done about it.
“At the moment, there are too many unknowns about the sewerage system, too many unknowns about water quality.
“You get something like this in nationwide, we can really raise public awareness and political awareness, and then we have to have that tough conversation about what we’re going to do about it.”
Across England, there were over 300,000 sewage spills in 2022
And he is perfectly happy to get to grips with the dirty end of the stick too.
I join him mid-stream, up to our waists in the River Brent just beside a massive drainage pipe.
The water around us is flecked with fragmented toilet paper and twigs trapped beneath the surface are draped with a flowing beard of dirty tissue.
‘It does whiff’
Thankfully we are in waders, but it does whiff.
We are installing two types of sensor.
One is static, fixed to a stake hammered into the river bed, the other their new floating design.
It is tethered to a paving slab on a length of rope.
It has a solar panel on the top, a box of electronics beneath, sitting on the inflated inner tube while dangling below in the water are the actual sensors.
When the river rises after heavy rain, it remains on the surface and able to communicate 24/7.
This is important as pollution is often worse when the sewerage system is overwhelmed in a downpour.
Across England, there were over 300,000 sewage spills in 2022.

The Environment Agency faces accusations of failing to protect our waterways but its budget has been cut by half in the past decade and Lewis Elmes, the area catchment coordinator, says they will gladly accept help from talented amateurs.
He said: “It complements what we’re doing, as it really increases the scope of what we’re able to achieve by producing a bit of equipment that’s so much cheaper than our much more expensive bits of kit.
“It really allows us to work to expand the boundaries of what we can look at in our rivers and the amount of outfalls that we can keep an eye on.”
River Brent’s own ‘Q branch’
The Environment Agency is trialling the brilliant shed tech from the River Brent’s own “Q branch” over the next year.
If it works the idea could go nationwide giving a much clearer, immediate picture of water pollution.
When it comes to fighting back, knowledge is power.
Counter-terrorism police are investigating after an incident involving a crossbow and a firearm left two women injured in Leeds.
Police were called to Otley Road at 2.47pm on Saturday to reports of a “serious incident involving a man seen with weapons”, West Yorkshire Police said.
Officers arrived at the scene to find two women injured – and a 38-year-old man with a self-inflicted injury. All three were taken to hospital, with the man held under arrest, but their injuries are not believed to be life-threatening.
“Two weapons have been recovered from the scene, which were a crossbow and a firearm,” Counter Terrorism Policing North East said in a statement.
The incident happened on the ‘Otley Run’ pub crawl, with one venue saying it was closed for the evening due to “unforeseen circumstances”.

Counter Terrorism Policing’s statement added: “Due to the circumstances surrounding the incident, Counter Terrorism Policing North East have taken responsibility for leading the investigation with the support of West Yorkshire Police.
“Extensive enquiries continue to establish the full circumstances and explore any potential motivation.”
Home Secretary Yvette Cooper described it as a “serious violent incident” and said she was being kept updated by police.
“Thank you to the police and emergency services for their swift response,” she said. “My thoughts are with the victims and all those affected by this attack.”

Wrexham AFC have been promoted for the third season in a row.
The North Wales-based side has gone from the National League to the Championship in just three seasons, under its Hollywood owners Ryan Reynolds and Rob McElhenney.
Wrexham were second in the table and had a run of eight games unbeaten ahead of their match against Charlton Athletic on Saturday, which they won 3-0.

It is the first time any club has been promoted for three consecutive seasons within the top five tiers of English football.
The third oldest association football club in the world, Wrexham AFC was bought by Reynolds and McElhenney in 2020, and has since been the subject of a Disney+ documentary, Welcome To Wrexham.
Reynolds, wearing a Wrexham sweatshirt, and McElhenney were pictured celebrating each goal, and after the game, as the fans came onto the pitch at the SToK Cae Ras (Racecourse Ground) to celebrate the victory with the players.

Both stars came onto the pitch after the supporters returned to the stands.
Speaking to Sky Sports, McElhenney praised those behind the scenes, referring to “so many that don’t get the credit they deserve, people who aren’t talked about”.
Reynolds said bringing success back to the club “seemed like an impossible dream” when they arrived in North Wales in 2020.

He put the three promotions down to “the coaching staff, the greatest dressing room” and an “all for one, one for all” attitude throughout the club, adding he was “speechless with their commitment and their emotion”.
As for the mouth-watering prospect of another promotion to the promised land of the Premier League, the pair agreed it was “for tomorrow”, before ending the interview with a joint mic-drop.
Veteran striker Steven Fletcher said, “as soon as I came to this club, I knew it was something special. We want to go again. We’ll reset in the summer, take a break and go again”.
“It has been a success.”
Just Stop Oil (JSO) insists it’s been “successful” – as its members ceremoniously hang up their orange high-vis vests during a march in central London.
Since the group formed three years ago, it’s drawn attention and criticism for its colourful, controversial protests, which ranged from disrupting sporting events to throwing soup on Vincent van Gogh’s Sunflowers, and climbing on gantries over the M25. It sprayed orange paint over Stonehenge, and cost police forces tens of millions of pounds.
Those days are now behind it; to the relief of many.

As a few hundred activists marched through London on Saturday, blocking roads as they went; taxi drivers blared their horns and football fans shouted abuse from the pavement.
The PA News Agency filmed the moment a white minivan seemed to drive towards a group of protesters blocking the road.
Protesters shouted “I’m being pushed back!” to police, while the driver could be heard shouting “What about my right to get home?” to the officers gathered.
But JSO never set out to be popular. And it believes its tactics – though hated – have been successful; thanks to the new Labour government’s commitment to not issue new oil or gas exploration licences.
That’s why, it says, its ceasing direct action.

“This moment marks the success of the JSO campaign – our demand was to end new oil and gas licences and that is now government policy.
“As a result of which four billion barrels of oil are being kept under the North Sea. The campaign has reached a natural end.”
Dr Oscar Berglund, senior lecturer in international public and social policy, disagrees that JSO is disappearing because it’s been “successful”.
He told Sky News policing strength and public perception might have more to do with it.
“They have very low levels of popularity. About 17% of the British population are kind of broadly supportive of what Just Stop Oil do. And that’s too low to recruit.
“It’s difficult to recruit members to something that is that unpopular, and then that a lot of people for good reason I think have kind of stopped believing in that kind of disruption as a means to achieve meaningful change.”
Group triggers specific new protest laws
One thing it did change is the law.
Policing commentator Graham Wettone tells us: “Obstruction of the highway, obstruction of rail networks for example, these are specific offences now.
“It’s given the police more tactics, more methods, more offences they can consider, even stopping and searching somebody who may have something to either lock themselves on or glue themselves to something.”

Emma Smart was held in prison for her activism with both Insulate Britain and Just Stop Oil.
“The high-vis might be going away,” she tells me, “but we aren’t.”
“These people aren’t going anywhere, we are still committed, dedicated, terrified by the failings of this government and governments around the world.”

She hopes for a time of reflection before it returns in a new form but says the need for climate activism is stronger than ever.
She also believes that while most people dislike JSO tactics, it still raises awareness of the cause and might even push people to more moderate campaign groups.
Just Stop Oil came behind other, similarly controversial climate campaign groups like Insulate Britain and Extinction Rebellion, and as it says goodbye, its disruptive methods have been seized upon by other organisations like the Pro-Palestinian Youth Justice.
The infamous Just Stop Oil orange vests might be going away, but the individual activists, their cause and campaign tactics feel here to stay.
