No water - couple of questions…
Discussion
Where we live we have had no water for 24hours, a bit inconvenient but no more
We had a small supply of water for scenarios like this, but when that ran low we go in the car and went somewhere that had it and filled our bottles from a tap
Loo flushing is with a bucket or watering can depending on what the output is, supplied by the water butt in the garden
I have two questions
1. A friend lives on one end of the Street and another at the other end. One house has water and one doesn’t. I get it that they are on different circuits so to speak. Are the circuits directional? I thought they might just be a massive sort of interlinked web, much like the internet, so if one pipe is switched off, the water will take the less path of least resistance (I appreciate this opening probably happen where different suppliers meet) and both friends will get a supply (unless their individual house supply is buggered )
2. I’ve been sloshing the turds down the loo for the last day with a bucket of water, followed up by a watering can or two to help it keep its momentum into the sewer. Where 58000 homes have been without water for 24 hours, when it starts to come back, will the sewers struggle to cope with the mass of tissue etc?
I assume it’s usually helped along it way / lubricated with grey water (shower / bath / washing up etc)
If the supply is turns on and every house only has a flush or two up,it’s sleeve (due to low pressure) will the dirty end of water start to have issues
I’m guessing the sewerage plants probably have tankers on standby to help?
Thanks

Are you sure it is not just a case of one house having an indirect plumbing system and a buffer of the cold water tank in their loft, vs someone else with a mains pressure system where everything goes down with the supply?chrisch77 said:

In this case the area without water is all connected to the Testwood plant. That covers a huge area, but at the fringes of that area there could be streets where they are on that system while another street is on (say) the feed from Otterbourne.
When Otterbourne was off last year we had water, but we are close to Otterbourne. Now we don't have water...

Guessing here, but if you have everything connected to everything and there's a massive leak, everything drains. If you have it all on separate branches you can lose a branch and everyone else still has water. Even if everything was connected, when you get a big leak somewhere you'd need to turn off valves somewhere to isolate it, and there would be a lot of houses between each valve.A massive chunk of Southampton has no water, but there are scenarios where houses on the same street have different feeds, I was wondering why it’s not like the internet model where every thing takes the cheapest (least resistance in water terms) hops
I'm thinking of it a but like house electrics, multiple spurs/rings from a central distribution panel, so I can turn off part of the house to do work without having to turn everything off.

I appreciate nothing is simple as it looks to an outsider

My money is on a contaminated supply. Something nasty they don't want to admit to because the claims would be expensive.I’m an adult and it’s part of life, the knock on issues are crazy
Everyone at my wife’s work who could make it in was late because the bottle collection point had massive queues

We're SO15, and unaffected. looking at the map I'd say we're a few hundred yards clear of the affected area.I’m an adult and it’s part of life, the knock on issues are crazy

I feel your pain.
Just goes to show the privatisation of these water companies does not work, share holders being paid out each year instead of investment into fixing dated water pipes and infrastructure!
If when homes do get water back on there maybe derb's in the water which will clog up your combi boiler filters and water test kits should be supplied before you dare drink it!

I've done a little work in utilities design over the years (mostly within large industrial sites) but with reference to question 1) - Generally speaking, the water supply network, is indeed a series of interjoined networks, which allow bidirectional flow and hence have the ability to back-feed areas where necessary for operational reasons. (burst main, isolation for maintenance etc)
The primary design intent is sizing of pipes to ensure flows and pressures are maintained evenly through quite a wide network, even at the end of a 'run' (furthest from a pump station or storage tower/tank) but to also 'organically' ensure a regular turn over of water (flow) occurs in all parts of the network and hence avoid dead legs. This is done to ensure the network meets domestic and commercial pressure and flow requirements, but also that of flow rates to fire hydrants which are dotted around the network.
At a slightly more micro level, networks are often then sub-divided into 'strategic zones', which is done for operational and/or maintenance reasons and also affords the network operators the ability to more accurately measure and monitors flows in specific areas (particularly for leak monitoring/detection purposes but also allows them to quite accurately pin point any water quality concerns. In some instances, valves (isolation or check valves) will be used to segregate particular areas or streets (even mid run along a single street) and hence you end up in a position where some houses on a road have supply and others do not - this certainly won't be on a street by street basis though...although it would appear that is the case in your example.
One thing is for sure, you certainly cannot assume all houses are 'dual fed' from the point which your supply service tee's off the main in the road....as its quite possible that that specific main is itself a spur from a larger main...and even if it was 'dual fed', the chances are that the specific 'strategic zone' you are located in is served from the same local pump station / supply from both sides of the tee.
