Bin the Wipes, All of Them | A Drain Engineer's View

The government's move to restrict plastic-containing wet wipes is welcome. I'm not here to argue against it. But the coverage has created a comforting idea that the problem is being handled, and I want to push back on that, because what I see coming out of drains in Solihull tells a different story.

This isn't a post about whether the ban is good policy. It's about what happens underground when people assume 'plastic-free' or 'biodegradable' means 'safe to flush'. Because it doesn't. And I'm pulling the evidence out of pipes across B90 to B94 on a weekly basis.

The replacement wipes are the real issue now

Manufacturers have been ahead of this for a while. The plastic-free pivot is already done. Walk into any pharmacy or supermarket and you'll find wipes marketed as plant-based, compostable, eco-friendly, and yes, flushable. The packaging is confident. The claims sound reasonable.

Don't flush them.

I had a job in Monkspath a couple of months back. Kitchen backing up, bathroom slow to drain, a smell that had been worsening for the best part of a week. We got the CCTV camera down and found a classic fatberg in formation. A solid mass of wet wipes, cooking fat, and assorted bathroom waste sitting in the lateral drain about four metres from the house. Not catastrophic yet, but another few weeks and it would have been a serious job involving excavation.

The homeowner was mortified. She'd been buying 'flushable' baby wipes. She'd read something online about biodegradable wipes being fine for drains. She's not gullible, she'd been misled by marketing that is, frankly, still not honest enough.

What 'biodegradable' actually means underground

Biodegradable means the material will eventually break down under the right conditions: heat, moisture, time, microbial activity. Your drain pipe is not a compost heap. The wipe enters the pipe, picks up a coating of grease or soap scum, snags on a tree root intrusion or a slightly offset joint, and it sits there. The fact that it might decompose over months or years is completely irrelevant when it's causing a blockage today.

I've pulled 'biodegradable' wipes out of drains in Olton and Lode Heath that look almost identical to what went in. Intact, cohesive, and wrapped around a growing ball of other debris.

Toilet paper is engineered to disintegrate in seconds of contact with water. That's the whole point of it. Wipes are engineered to stay intact through use, to be robust enough for whatever job they're doing. You cannot design something to survive vigorous use and then claim it'll fall apart the moment it leaves the toilet. The physics doesn't work.

The 'Fine to Flush' standard, run by Water UK, is a certification that tests whether a product breaks down safely in the sewer system. A product carrying that mark has passed a set of disintegration tests. Most wipes on sale don't carry it. Some that claim to be flushable have never been near the testing process. And even the ones that pass the test are not the same as toilet paper. Not close.

What I see across Solihull

This isn't a London fatberg story. Severn Trent spends millions a year clearing the sewer network across the West Midlands. Some of that cost feeds back into household bills. Some of it lands directly on homeowners when the blockage sits on the private lateral drain, which is your responsibility to fix under current rules, not Severn Trent's.

The pattern I see in Hillfield, Elmdon, Bentley Heath, Hockley Heath, and Castle Bromwich is consistent. Older properties with narrower pipes and minor structural imperfections, slight root ingress, an offset joint from ground movement, a partially collapsed section, all of them acting as collection points for wipes that shouldn't be there. In newer builds like parts of Dickens Heath and Monkspath, the pipes are cleaner but the habit is the same. The wipes still accumulate.

If your property was built before the 1980s, particularly in older village streets around Dorridge, Hampton-in-Arden, or Knowle, your drainage is more likely to have those small imperfections that turn a partial wipe blockage into a serious one. A CCTV drain survey will tell you exactly what's down there.

What the trade has been saying

The NADC, the National Association of Drainage Contractors, and most working engineers have been saying the same thing for years. The ban addresses manufacturing. It does nothing about behaviour. And behaviour is the actual problem.

The three Ps. Pee, poo, paper. That's it. Nothing else belongs in a toilet. Not cotton pads. Not nappies. Not kitchen roll, which a surprising number of people treat as a substitute for toilet paper. Not 'flushable' wipes of any description, plastic or otherwise.

Everything else goes in the bin.

The practical point

If you've been flushing wipes and you've noticed slow draining, gurgling, or smells, don't wait for a full blockage. High-pressure water jetting will clear most wipe-based blockages before they set into something that requires a lot more work. If you've had a blockage cleared and you want to know whether your pipes have taken any damage, a CCTV survey is the logical next step. It gives you a proper picture of what's down there, not a guess.

Bin the wipes. All of them. Plastic, plastic-free, biodegradable, and definitely anything that calls itself flushable. Don't wait for legislation to do the thinking for you.
