Twitter and the media is awash with lies, half truths and misconceptions about the state of UK rivers, sewage overflows and water privatisation.

It's a complicated topic, it's going to be a long 🧵

1️⃣ Many reading this will think that the following points are true

🔸 UK waters are worse than ever
🔸 EU water is much better
🔸 Tories voted to dump sewage
🔸 It happened after Brexit
🔸 It's due to privatisation

All of these are wrong. I'll show you why.

2️⃣ Let's start with some basics. This is a bit dull but necessary.

There is 250,000 km of sewers throughout England of which around 100,000 km is combined. This means surface water (ie rain) and waste water use the same pipes. Since the 1960's new sewers have been separate.

3️⃣ When it rains heavily and the system gets too full the options are for it to come back up your toilet or into water bodies via CSO pipes. All of these pipes have existed for 150 - 60 years. This is not a new problem.

CSO's are not a bug, they are a feature.

4️⃣ Every sewer system in the world has CSO's. England has just under 15,000 of the UK's 22,000.

Europe has around 330,000 CSO's.

USA totals are sketchy but they release 800 BILLION gallons of combined sewage a year! 💩

They aren't going anywhere.

5️⃣ So why all the uproar about them now when sewage has been flowing into rivers forever?

More data.

In 2014, Richard Benyon MP led the charge for all CSO's in England and Wales to be 100% monitored by 2023. In 2016 when the rollout started only 5% were monitored.

6️⃣ This led to misleading graphs like below being spread around Social Media and politic opponents of the Government using it to purposefully mislead the public.
There was no increase in sewage overflows, only an increase in monitored events.

7️⃣ Here's an incredibly misleading story from @SkyNews without even the bare minimum of scrutiny. If this is "Labour's analysis" of the data as the story says, you have to question their ability to run the country.

8️⃣ It's not just Sky. This story was on every news channel and in every newspaper without a single one of them mentioning it was down to more monitoring not more sewage.

9️⃣ It's important to note that CSO's work much like the overflow in your sink. It's an automatic process that's triggered when safety limits are reached.

There is no fat cat CEO with a "Dump Sewage" button on his desk.

1️⃣0️⃣ The systems that this Government brought in to improve the problem have been used very effectively against them. Many still believe the "The Tories voted to allow sewage dumping" lie.

1️⃣1️⃣ Despite a lack of monitoring the issue of sewage overflows has almost certainly got better, not worse. Especially in urban areas. Testing going back to the 70's shows Ammonia and BOD levels associated with sewage declining markedly in rivers.

1️⃣2️⃣ Which brings us to water quality testing.

You will frequently see headlines such as the one below that highlight a decline in how "Good" our rivers are.

theguardian.com/environment/20…

1️⃣3️⃣ Activists such as Feargal Sharkey often us them to show a decline in English rivers since 2009 when monitoring under the EU Water Framework Directive began.

1️⃣4️⃣ What nobody ever mentions is that a large reason for the decline is the EU added more substances to test for and thus fail against in 2015 leading to a decline in numbers. Then again in 2019 they added uPBT's.

Around 40% of the decline is due to these added substances.

1️⃣5️⃣ The rest of the decline is likely not due to sewage. Only 36% of pollution is down to overflows says Owfat. The largest polluter at 40% is Nitrogen and Phosphorous from farming run off.

Which is why the Gov introduced Farming Rules for Water in 2018.

1️⃣6️⃣ What is always missing is context so that the UK seems like a poor outlier.

The UK may be 14% "Good", around the same as Belgium, but Germany is only 8% and The Netherlands less than 4%. Most of mainland Europe is no better than the UK.

1️⃣7️⃣ The same goes for coastal bathing waters.

93% of UK bathing waters are rated good or excellent, up from 70% in 2009 and nearly double what is was in the 1990's. This is comparable to EU countries where the average is also 93%.

1️⃣8️⃣ Another common attack line on English water is privatisation and lack of investment.

What those same people fail to mention is that Scotland and Northern Ireland are publicly owned, and Welsh Water is a not "Not for profit" funded by the Welsh Gov.

1️⃣9️⃣ These problems persist in the devolved nations with large amounts of sewage via overflows. England has less clean water leaks per head in the UK. Nearly half those of Scotland and NI.

Since privatisation investment has increased significantly in England.

2️⃣0️⃣ Between 2020 and 2025 we are investing more in water infrastructure than any European country. And this is before the announcement yesterday (May 18th) of £10bn extra specifically for sewage upgrades.

2️⃣1️⃣ I could talk more on how the Water companies work and how our bills have not gone up in 20 years despite all the investment above but the excellent Robert Colville covered it in depth last year.

2️⃣2️⃣ Uk waters are better than they have ever been. More attention is being paid to it than ever before. More money is being spent on it that ever before. Believe it or not the current government have done more for water quality than any past government.

2️⃣3️⃣ That's not to say they are perfect, there is more to be done. The Gov have been dragging their feet on removing the right for new builds to connect to sewers and more funding for the EA to monitor and prosecute water companies and farmers is required.

2️⃣4️⃣ But things are nowhere near as bad as social media and the media would have us believe and things are better, not worse.

Just to add to this,

Do not use flushable wet wipes.

Wet wipes have increased blockages 400%. They cause the vast majority of blockages and overflows when it isn't raining.

The Gov has been banning them for about 5 years but keeps dragging their feet.

I wanted to add another example of intentional misinformation with another excellent thread by Robert Colville tearing apart a Guardian article widely used to mislead.

Feargal has entered the chat.

It's very clearly not illegal, read the Water Industry Act.

And the EU took every EU country to court in 2012 as an act of political theater.
