The Canal & River Trust’s marketing department loves a catchy slogan, for example 'Better by Water'. What they preach to the public, conjures up a picture of tranquil towpaths, bobbing ducks, and picturesque stone bridges and brightly painted boats.
But for those who actually live on, navigate, or reside next to the 200 years old network, the reality under CRT’s stewardship feels less like a peaceful sanctuary and considerably more like a game of structural Russian Roulette.
When marketing gloss clashes with canal engineering, reality always wins. The earthworks of the canal system do not read press releases, nor do they pay attention to public relations management. They obey the laws of soil mechanics, pore pressure, and century-old masonry integrity.
Engineering failures and near misses
We do not have to look far back to see what happens when earth heritage is neglected in favour of corporate image.
Toddbrook reservoir (2019):
The structural partial collapse of the spillway at Whaley Bridge wasn't a minor inconvenience; it forced the emergency evacuation of over 1,500 residents. It took a RAF Chinook dropping aggregate bags and days of round-the-clock pumping to prevent a catastrophic inundation that would have wiped out homes and lives downstream if it wasn't for the prompt action by the emergency services who evacuated nearby premises.
Whitchurch (2025):
The debacle on the Llangollen Canal at Whitchurch showed a shocking disregard for operational safety. When the embankment failed, sending thousands of tons of water and subsoil cascading down the slope, it wasn't just navigation that halted. Boaters were left stranded above and in a degrading breach, exposed to catastrophic structural movement before proper isolation and dewatering were managed. Risking the lives and livings of boaters while slow-walking emergency protocols is a damning indictment of modern waterway management. Lucky it didn't occur later in the day, when dog-walkers could have been in the vicinity.
Is Nantwich next?
Now, all eyes turn to Nantwich on the Shropshire Union. The historic embankment there—carrying millions of gallons of water high above the surrounding Cheshire landscape—is showing the distinct, unmistakable signs of distress.
Yet, instead of deploying immediate, heavy structural remediation, CRT seems content to rely on modern digital placebo measures. Through their favoured, tame YouTube channels, the trust has been keen to talk up the deployment of bank monitoring sensors. Let us be completely clear about what bank sensors do: they measure movement; they do not prevent it.
A telemetry node embedded in a collapsing clay core will happily register shear stress and transmit a signal right up until the moment the bank washes out into the houses below. A sensor will not magically alter the time, physics, or rate of a structural slope failure. Placing a stethoscope on a dying patient does not cure the disease—it merely records the time of death.
The official response to the growing concern at Nantwich? The trust assures us they will get round to fixing it 'after Christmas'.
It is a remarkably relaxed timeline for a high-hazard asset. Apparently, CRT’s operational management believes that soil erosion, water pressure, and structural settlement operate on a civil service derived time table and respect seasonal holidays.
The trouble is, the earth embankment at Nantwich takes no notice of CRT press releases. It does not care about financial year-ends, corporate PR cycles, or Xmas break schedules. Water finds the line of least resistance, and when pore pressure exceeds the shear strength of an ill-maintained bank, it will go—whether it is Christmas Day, Boxing Day, or a rainy Tuesday in November.
The regulatory void
Ultimately, the Canal & River Trust has proven beyond doubt that its water-holding assets are not in a safe pair of hands.
In the immediate aftermath of the Toddbrook Reservoir scare, the legal framework governing reservoir safety—principally the Reservoirs Act 1975—was rightly subject to intense scrutiny, review, and modification to statutory safety recommendations. The state recognised that high-consequence impounded water represents an existential threat to downstream communities and demanded stricter regime oversight.
Yet, for reasons that remain entirely unfathomable to anyone with an engineering background, raised canal embankments are exempted from this same rigorous statutory legislation. Functionally, a massive earth embankment retaining thousands of tonnes of water high above residential housing presents a threat identical to that of a conventional reservoir wall. A breach at Nantwich would carry the same lethal energy potential as a failed spillway at Whaley Bridge.
That statutory legislation continues to treat elevated earth canal banks as mere agricultural retaining walls—rather than critical, high-hazard water infrastructure—is a regulatory blind spot waiting to end in tragedy.
If CRT continues to prioritise its image and digital gimmicks over fundamental civil engineering and statutory accountability, 'Better by Water' won't just be an empty marketing slogan—it may well turn out be an epitaph for some poor souls that were in the wrong place at the wrong time.
