The UK Government is debating whether to fit around 10 million of them in
the South of England, perhaps you should wait until the order is placed?
Bulk pricing?

Yes, it will go UP by 200% due to the specialised interface, non
standard thread and targeted health and safety requirements that some
beurocrat will impose on the order. They will arrive 2 years late and
be installed backwards. They will of course be supplied from China thus
depriving a uk industry of work. The remote interface will not be
compatible with any other hardware or software in existence. This will
kick off a massive software contract to one of the big contracting
house to build a remote billing package. The proof of concept test will
send out credit notes to everyone involved in the pilot and make
demands for the negative sums to be paid immediatelly. 3 people will
end up in jail over unpaid council tax bills.

6 months into the actual project the public will riot in the streets
because they realise that their water is being measured in litres
rather than cubic feet, however the project will proceed in spite of
the public outcry.

During all of this the water companies will have decided that they have
been instrumental in transforming the face of resource usage in the UK
and will award their board members 50 million pound bonusses.

At the end of the project someone will discover that to save costs the
installation contractors omitted the required PTFE thread tape and
there are 10 million water meters all leaking 1 litre per hour into the
ground thus negating the point of the whole project.

An enquiry will go out for 1 million 50000 litre water tankers, to be
parked at the end of each residential street with suitable brass taps
to allow housholders to collect supplies in plastic drums. ( hey they
do it in Africa it must be a workable solution )

Actually it wont be a problem because all the reservoirs will be empty
and there wont be any water to deliver anyway.
