Free tap water with Refill London

My first comment is that potable water is not free, paid for by someone such as taxpayers, be they private or business rate taxpayers. But this, naturally, does not concern the Mayor or his administrators.
While it will be great if businesses continue to offer this facility I feel that the Mayor should initiate coin operated refill points throughout London. This would be the modern equivalent of the many drinking water fountains that existed when I was young but which have disappeared today. I saw coin operated water dispensers in use in America and found them convenient and economical.

Was common in 19th century Paris "les wallaces"

Donated by and Englishman - he of the Wallace Collection and still functioning
But there was no safe drinkable tap water as now

The madness of carrying a plastic bottle was promoted by sellers of bottled water only a few decades ago - pretty pointless in a temperate climate - it's those who should be surcharged with a specific tax

In general it sounds good, but what is the cost to us in the City of London? What do we give up to get it? Most of the usage is going to be by tourists I wager. That does not diminish the importance, but all such issues need to be analysed from a cost standpoint. Also, how are these kept sanitary?

A great initiative and long overdue. Single-use plastic of any kind is disgraceful. Bring back glass bottles with a deposit scheme - just like the old days!

It's a good idea, but doesn't go nearly far enough: there should be public water fountains available throughout London, particularly in all parks and public buildings (eg libraries, hospitals, schools, etc.) - and which DON'T require people to have carried their own bottles with them.

I accept that this scheme, if adopted sufficiently widely by local businesses, will go a long way to helping, but the government needs to spend some its own money to install public water fountains, too.

This is a great idea that needs to be expanded to Greater London to reduce plastic waste and help the environment. hope other cities will follow.

Excellent idea. It will contribute to the plastic bottles decease and also prevent people from fainting when hot and humid.

Excellent idea, as long as all taps are regularly inspected and there is some method of reporting faulty taps which are then maintained promptly, so as to prevent any wastage.
I particularly favour water being available on tube station platforms and at airports, to cater particularly for times when transport is severely delayed in the heat, or for many hours when food and drink outlets may have closed.

Really! total waste of money, yes I also drink water go to the gym go running etc and I carry a re useable bottle. Stop wasting time and money on this and take action on knife crime. Once it is safe to walk the street of London then we can worry about water fountains.
