That still doesn't add up for me... the total amount of infrastructure per person will still just be a lot higher for rural areas, can't see that being outweighed by relatively simple maintenance for the bits which literally just run through fields or along quiet country roads.
The infrastructure required and the costs involved will be different, though.
In rural areas you can put in pretty much whatever you like. The more densely populated an area, the more restricted you are on what you can fit in there and what will work.
For example, a rural area catchment of 1600 properties will benefit from balancing ponds and other flood alleviation measures at a relatively low cost (say, £2mil for a large one), whereas somewhere like London might require a FLIP device to be installed at each at-risk property, costing about £40,000 each for a total of £64mil.
The infrastructure within villages will still have silmar issues around digging up roads etc. And any infrastructure that runs through properly remote areas will have additional access challenges compared to infrastructure just off a main road.
Village infrastructure is mostly in undeveloped land and minor roads. Works are unlikely to impact railways, bridges, buried services, SSIs, graded buildings, schools, hospitals, or any of that stuff.
Physically accessing sites is also quite easy in remote areas, whereas you can't just pick up a London railway station and move it aside while you work on the stuff beneath.
If it's so much cheaper to provide rural fibre broadband the why is the government spending hundreds of millions of pounds subsidising it with their voucher scheme etc?
Dunno. We got our rural fibre without needing any vouchers... but we are also serviced by someone who isn't one of their scheme suppliers.
It sounds more like government fingers in profitable pies, than anything else.
Flip that around. Why do rural areas traditionally have much worse landline speeds? It's more profitable in dense areas?
Because the cost of putting up telephone poles and laying/upgrading wire per metre is basically the same wherever you go, and rural areas needed more of them?
Also those rural areas might need to run hundreds of metres for one house. Where as in London you can supply 100s of residents connecting up one tower block. Which has probably been built taking water supply into consideration.
Rural pipe might cost £300 per metre, where the same pipe in suburbia would cost £3500 and in a city centre could easily be £5000.
Higher population desnities also tend to require larger diameter pipes to cope with the heavier flows, and often you'll need to go even larger to accommodate the commercial/industrial needs as well.
In places with really dense populations you won't have the space to put enough large diameter pipes in, so you'll double-barrel them as with the Oxford City Trunk sewer and the five-barrel Northern Outfall Sewer.
He is right at the micro level it is far more expensive to dig up services in London for example.
And maintain.
OPEX is massive in built-up areas.
Thames is on average the most densely populated water company because of London of course, but their rural areas pull them back somewhat. If a water company only supplied London (as was proposed, to split up Thames), then they would have much higher network maintenance costs on average than the current company does.
TW also has to deal with Luton, Slough, Oxford, Swindon, Reading and Basingstoke, which have some of the highest population densities per area in the UK.
You're also right that some aspects of rural areas are more expensive too. Digging up pipes is cheaper in rural Wales but its true that you have more pipe per head in rural Wales than you do in central London.
You often have longer single pipe runs in rural areas, but built-up areas have lots of short runs making up the networks. The latter is also more likley to have additional back-up networks, in the event of failure and to transfer flows between catchments as demand and capability vary.
