Birmingham draws its water from reservoirs in Wales rather than the Lickey Hills ..... That's the reason they have a "surplus"

But the question was where is it going NOW. Back to Wales, to the North Sea or some other location?

I'd imagine it goes in to the canals and  rivers via the sewage treatment works.

[Tony Brooks]

At least some of it probably goes down the Shroppie. Hence, the fierce bywashes.

So half to Wales and half to ?

I don't see how you get half to Wales, I would expect the lot to go to the Mersey via Ellesmere Port, unless it had been dumped into a watercourse before that.

Grand Union Canal - Braunston to Cowley Lock Uxbridge

DetailFrom Date: 26/07/2024 10:00

To Date: 31/011/2024 10:00 inclusive

Type: Water Movememt

Is the towpath closed? No, but might be flooded in some locations.

cation

Closest waterway: Grand Union Canal

Starts at: Bridge 1 (Roadbridge)Braunston

Ends at: London Paddington Pound

NAVIGATION IS SUSPENDED UNTIL FURTHER NOTICE

Due to the extreme water shortage situation in the London urban area and South East in general, the use of the Grand Union Canal is reverting to Oasis status and navigation is suspended for the forseeable future. Locks will be used as overflow wiers in the downhill sections and mooring here is not advised due to possible overtopping of the UK.Gov WaterSupplyChannel. Any boats moored up on the channel must make sure they have sufficient lines and anchors to withstand 3mph waterflow for several weeks, if not longer. Navigation will be not possible, even dangerous, and locks will be secured against passage.

Cosgrove area - This area may be severely impacted by the imposition of the UK.Gov Water SupplyChannel, and any boats moored below Cosgrove Lock must be removed to a safe location immediately. Not only will the flow negatively impact the structure surrounding Cosgrove Lock, but due to engineering oversight in the early 1800s, the Great Ouse Aqueduct may be negatively compromised, resulting in a local drainage of the channel.

THE GLOBE, Linslade

Evacuation of the local area is recommended, dont book a table and expect to find it in the pub, our pumps cant hope to cope with all the water you know.

We are sorry for any impact to your booked holidays or cruising plans but obviously, our water supply route is far more lucrative than a few cancelled hire boats. So long as you are floating, you are honoured to pay our annual licence fee, if not, contact your insurance company.

Thanks

Think it has already started at Hatton. There was a report in the Warwickshire news about the cafe being flooded on Sunday due to inconsiderate boaters not knowing what they are doing

It doesn't seem likely there's so much spare water that a 3mph flow would be plausible. Our in-house clever bods have already calculated a measly 0.5mph flow. It's also still possible to use locks while they're overflowing, unless it's a serious torrent...

 

While this is an interesting fiction, I think it is likely to remain fictional

What about shutting the navigation during the hours of darkness, providing more secure moorings, and increasing the flow rate significantly after dark?

 My view of consultants is that they make the process as complicated as possible and gold plate any projects that go ahead because they are on a percentage of the final cost.

Look at HS2.

 

And they don't always get it right. An example being HS2's original plan for the line to cross the T&M in 3 places between Fradley Junction and Handsacre, until a bloke from IWA Lichfield branch worked out a new route that would only cross the canal once, and would save HS2 £55 million. They obviously changed their plans and adopted his.

 

I wonder how many other HS2 locations elsewhere are costing more than they should be.

If they were asked "plan the quickest and easiest route from A to B and tell us what it would cost" then that's exactly what they'll do, they don't have any incentive to save HS2 money.

 

If they'd been told "find the cheapest way to get HS2 from A to B" then the answer would have been different -- but HS2 are more concerned with speed because that's their USP, cost is SEP (Somebody Else's Problem).

 

In my experience consultants do what they're told (and no more), and any problems like this are usually due to poor instruction or definition of the task -- in other words, down to HS2.

 

So there may well be loads of similar cases all along the HS2 route, which will all in the end come down to HS2 incompetence. Quelle surprise... 😞

Well back to the water supply

 

In Birmingham as stated the supply is via the Elan Valley, in Staffordshire there is South Staffs water

 

It is used for industrial and domestic use

 

There are those that regularly water their drives and that water ends up in sewers or streams and rivers

[agew]

Probably been mentioned in the pages I skipped - but the consultation map seems to show it only uses the Grand Union from Braunston south, Brum to Braunston is North Oxford/Coventry.....  Just being picky...or wrong of course....

An interesting plus point for boaters, assuming the scheme ever makes it into reality...

Canal customers and users

We’ll be using existing canal infrastructure, owned and managed by the Canal & River Trust, to bring the water from the Midlands to the Southeast.  This means we won’t need to build unnecessarily and minimises the use of new materials.  We’ll also make improvements to the canal network to secure its long-term sustainable future, keeping it open and alive, resilient and safe, and maximising its value to people, nature and the economy.

Does that mean they won't be bodging the canal by using concrete because they will use lime based materials

Well, starting at Minworth isn't exactly ideal if you want to go down the Northern GU.   A pipe to Tyseley is probably shorter than one to Atherstone,  but I doubt many would  fancy excavating their way through Brum.   Then  the long drop from Knowle to the Cape at Warwick is fine, but the equally long climb back to the Braunston level needs a lorra lorra pumps and would be very expensive to operate.

The route via Suttons makes much more sense.

 

Even so, the whole idea will soon founder on engineering reality and operational limitations, IMO.

I did a calc and agree with the 0.5mph. However, put put a full sized wide beam in the tunnel taking up lets say 75% of the available flow area and if the widebeam is stationary the current will be 2mph to get around the boat let alone make any headway. Therefore, the boat will not make any progress at low cruising revs. Has CRT thought about this yet or have I got something wrong.

Any under powered wide beam trying to head north through Blisworth tunnel can pick up some volunteer leggers at the south portal. Drop them off at the other end to walk back over the hill. 😀

[MtB]

A more obvious solution is to stop fatties using the tunnel.

 

Wins all round!!
