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.
Fresh appeals have been made for information on what would have been the 20th birthday of Ellis Cox, who was shot dead in Liverpool last June.
A number of people have been arrested in connection with the murder at Liver Industrial Estate, but no one has been charged yet.
The 19-year-old’s family and police have paid tribute to him and called for those with information to come forward.
He was shot in the back after a confrontation between his friends and another group of up to three males on Sunday 23 June.

His mother Carolyn paid tribute in an appeal to coincide with what would have been his 20th birthday.
“He was so kind… so laid back, so calm, so mature for his age. And he was just funny. Very funny.
“He was my baby… no mum should have to bury a child. He was my life. And I don’t know what to do without him.”

Meanwhile, his aunt Julie O’Toole said he was “the sort of person I think you’d be hard pressed to find anyone to say anything negative about. He was loyal, fiercely loyal… everything was about his family”.
To pay tribute to Ellis, Liverpool City Council will be lighting up the Cunard Building and Liverpool Town Hall in orange on Saturday.
DCI Steve McGrath does not believe Ellis was involved in criminality
Detective Chief Inspector Steve McGrath, the senior investigating officer, spoke about the information gathered so far, six months on from Mr Cox’s murder.
“I’m satisfied that the group that he was with was probably the target… and I would say that’s got something in relation to do with localised drug dealing in that area. But Ellis had no involvement in that whatsoever,” he said.
He added that police are looking for “really significant pieces of evidence now”, including “trying to recover the firearm that was used in relation to this, looking to recover the bikes that were used by the offenders”.

Mrs Cox also appealed for people to come forward with information.
“If you know anything, don’t let us get to [his] next birthday and still know nothing.
“We need to get justice for Ellis. And we need to get the people who took him from us off the streets.”

Reward of £20,000 offered to identify parents of three siblings abandoned as babies over eight years
A £20,000 reward is being offered for information that leads to the identification of the parents of three siblings found abandoned in London over eight years.
The Metropolitan Police said that despite more than 450 hours of CCTV being reviewed, the parents of the three children, known as Elsa, Roman and Harry, remain unidentified.
However, it is believed their mother has lived in an area of east London “over the past six years”.
Elsa was believed to be less than an hour old when she was found by a dog walker on 18 January last year, in East Ham, east London.
In the months that followed it was found that she had two siblings who were also abandoned in similar circumstances, in the same area of London, in 2017 and 2019.
On Saturday, police said the independent group Crimestoppers had offered a £20,000 reward for information passed to the charity, which will expire on 18 April.
Detective Inspector Jamie Humm, of the Met’s child abuse investigation team, said: “We have carried out extensive inquiries over the past year to try and locate Elsa’s parents.

“This has involved reviewing over 450 hours of CCTV and completing a full DNA structure of the mother.
“We have serious concerns for the wellbeing of the parents, especially the mother, and are continuing to work closely with Newham Council and appeal for the public’s help for information.
“I believe that someone in the area will have been aware of the mother’s pregnancies and that within the community there may be (or) have been concerns for this mother’s welfare.
“Thanks to the DNA work of forensic colleagues, police will be able to eliminate any unconnected person quickly and easily, as such I would ask you to contact police with confidence.”

Elsa was found wrapped in a towel in a reusable shopping bag, of which police have also released a new image, and was kept warm by the dog walker. She was uninjured.
Police said at the time that it was “highly likely” that she was born after a “concealed pregnancy”.

The BBC reported that at an initial court hearing, East London Family Court was told it took doctors three hours to record Elsa’s temperature because of the cold, and the Met Office said that temperatures dropped to as low as -4C on the night she was found.
Hospital staff named her Elsa in a reference to the character from the film Frozen.
The police investigation into the identity of the children’s parents continues, and anyone with information is asked to call police on 101 or post @MetCC ref Operation Wolcott.
People can also contact Crimestoppers anonymously at any time on 0800 555 111 or via Crimestoppers-uk.org.
