Upgrade water system to protect humans from ingesting trace of poo, Sir Chris Whitty-backed report says
The UK’s sewage system should be upgraded to reduce the risk of people ingesting human poo when they swim in rivers and the sea, a new report backed by chief medical officer professor Sir Chris Whitty has recommended.
The evidence base that people have become ill because they ingested traces of sewage while swimming remains “thin”, Sir Chris said as he unveiled the report, which was produced by a group of engineers.
But Brits are increasingly taking to the water to swim, surf and paddle, and some have become ill afterwards.
This increased exposure, combined with “evidence of the underperformance of overloaded sewers”, may increase the risk of people orally ingesting human faecal organisms, the engineers said.
It comes as a fresh row over water quality broke out last week after confirmed cases of the waterborne disease cryptosporidium were identified in Brixham in Devon – though it may have come from cow faeces which leaked into damaged pipes.
It also follows recent reports that millions of litres of raw sewage had been pumped into Lake Windermere.
While sewers were originally designed to reduce health hazards, over time inspections and investments have tended to focus more on the cost and environmental impact of sewage.
Now human health “also needs to be taken seriously”, Sir Chris told reporters.
Human poo can contain salmonella, campylobacter, E. coli and norovirus, which cause diarrhoea, vomiting, abdominal cramps, and fever.

While emergency discharges of raw sewage have been the subject of widespread public attention and anger, they are only “half the problem”, Prof Whitty said.
That’s because some faecal organisms that can cause disease remain even in treated sewage, which is routinely released into the water.
And people are more likely to enter the water in hot, dry weather, when water levels are low and sewage is less diluted.
‘Major wake-up call’
The report, led by the Royal Academy of Engineering, suggested a range of solutions to the UK’s crumbling water system, including a review of the way officials protect designated bathing waters.
It raised concerns that current bathing water quality testing – of just once a week in summer – is too infrequent and that some viruses are going undetected.
Water companies, who have been accused of chronic underinvestment, should “improve maintenance and rehabilitation of our ageing wastewater infrastructure”, said Dr Andrew Thompson from Fingleton White, who worked on the research.
The report also called on regulators to monitor not just untreated sewage going into the water but treated water too, and to make data available quickly to help people decide whether to go for a dip.

Charles Watson, chairman of the River Action campaign group, welcomed calls to improve water quality monitoring.
“Other than at the minuscule number of designated river bathing water sites, nothing is being done to provide river users with even the most basic information on the dangers they are facing.
He said politicians should treat the report as a “major wake-up call, given the past failures to protect the public from the rising tide of sewage pollution”.
The engineers also suggested introducing incentives to members of the public to remove impervious surfaces in urban areas – like patios or paved-over gardens, which would help green cities too.

A Water UK spokesperson said: “There is an urgent need to invest in our water system. Water companies have a plan with proposals to double the current level of spending between now and 2030… Public health is a major part of the next phase of the programme, with bathing areas heavily prioritised for investment.”
The environment department (Defra) said it will consult later this year on new bathing water rules – though this may not be until after the general election.
They added: “Alongside the Environment Agency securing over £150m fines to date and quadrupling inspections, we are already driving the largest infrastructure programme in water company history of £60bn over 25 years, which will drastically reduce spills.”

Zhenhao Zou: More than 20 new potential victims come forward after ‘prolific’ rapist jailed for assaulting 10 women
Another 23 female potential victims have reported that they may have been raped by Zhenhao Zou – the Chinese PhD student detectives believe may be one of the country’s most prolific sex offenders.
The Metropolitan Police launched an international appeal after Zou, 28, was convicted of drugging and raping 10 women following a trial at the Inner London Crown Court last month.
Detectives have not confirmed whether the 23 people who have come forward add to their estimates that more than 50 other women worldwide may have been targeted by the University College London student.
Metropolitan Police commander Kevin Southworth said: “We have victims reaching out to us from different parts of the globe.
“At the moment, the primary places where we believe offending may have occurred at this time appears to be both in England, here in London, and over in China.”

Zou lived in a student flat in Woburn Place, near Russell Square in central London, and later in a flat in the Uncle building in Churchyard Row in Elephant and Castle, south London.

He had also been a student at Queen’s University Belfast, where he studied mechanical engineering from 2017 until 2019. Police say they have not had any reports from Belfast but added they were “open-minded about that”.
“Given how active and prolific Zou appears to have been with his awful offending, there is every prospect that he could have offended anywhere in the world,” Mr Southworth said.
“We wouldn’t want anyone to write off the fact they may have been a victim of his behaviour simply by virtue of the fact that you are from a certain place.
“The bottom line is, if you think you may have been affected by Zhenhao Zou or someone you know may have been, please don’t hold back. Please make contact with us.”

Zou used hidden or handheld cameras to record his attacks, and kept the footage and often the women’s belongings as souvenirs.
He targeted young, Chinese women, inviting them to his flat for drinks or to study, before drugging and assaulting them.
Zou was convicted of 11 counts of rape, with two of the offences relating to one victim, as well as three counts of voyeurism, 10 counts of possession of an extreme pornographic image, one count of false imprisonment and three counts of possession of a controlled drug with intent to commit a sexual offence, namely butanediol.

Mr Southworth said: “Of those 10 victims, several were not identified so as we could be sure exactly where in the world they were, but their cases, nevertheless, were sufficient to see convictions at court.
“There were also, at the time, 50 videos that were identified of further potential female victims of Zhenhao Zou’s awful crimes.
“We are still working to identify all of those women in those videos.
“We have now, thankfully, had 23 victim survivors come forward through the appeal that we’ve conducted, some of whom may be identical with some of the females that we saw in those videos, some of whom may even turn out to be from the original indicted cases.”
Mr Southworth added: “Ultimately, now it’s the investigation team’s job to professionally pick our way through those individual pieces of evidence, those individual victims’ stories, to see if we can identify who may have been a victim, when and where, so then we can bring Zou to justice for the full extent of his crimes.”
Mr Southworth said more resources will be put into the investigation, and that detectives are looking to understand “what may have happened without wishing to revisit the trauma, but in a way that enables [the potential victims] to give evidence in the best possible way.”
The Metropolitan Police is appealing to anyone who thinks they may have been targeted by Zou to contact the force either by emailing survivors@met.police.uk, or via the major incident public portal on the force’s website.
An 11-year-old girl who went missing after entering the River Thames has been named as Kaliyah Coa.
An “extensive search” has been carried out after the incident in east London at around 1.30pm on Monday.
Police said the child had been playing during a school inset day and entered the water near Barge House Causeway, North Woolwich.
A recovery mission is now said to be under way to find Kaliyah along the Thames, with the Metropolitan Police carrying out an extensive examination of the area.

Chief Superintendent Dan Card thanked members of the public and emergency teams who responded to “carry out a large-scale search during a highly pressurised and distressing time”.
He also confirmed drone technology and boats were being used to “conduct a thorough search over a wide area”.
He added: “Our specialist officers are supporting Kaliyah’s family through this deeply upsetting time and our thoughts go out to all those impacted by what has happened.”
“Equally we appreciate this has affected the wider community who have been extremely supportive. You will see extra officers in the area during the coming days.”

On Monday, Kerry Benadjaoud, a 62-year-old resident from the area, said she heard of the incident from her next-door neighbour, who “was outside doing her garden and there was two little kids running, and they said ‘my friend’s in the water'”.
When she arrived at the scene with a life ring, a man told her he had called the police, “but he said at the time he could see her hands going down”.
Barge House Causeway is a concrete slope that goes directly into the River Thames and is used to transport boats.
Residents pointed out that it appeared to be covered in moss and was slippery.
