LONDON, July 19 (Xinhua) -- With London enjoying days of Mediterranean-type heat waves in recent weeks, Mayor Sadiq Khan has named 50 locations for water fountains across the British capital.

The mayor's program of installing fountains to provide free drinking water is part of his drive to dramatically reduce the number of plastic bottles used in London.

New locations include Russell Square, Camden High Street, Greenwich and 20 London Underground and railway stations.

Locations of first 50 new water fountains revealed also include shopping and business districts, green spaces and busy high streets.

The new fountains will be added to the existing 28 already installed through the mayor's initiatives. Two of the fountains at Liverpool Street Station dispensed 8,000 liters of drinking water, the equivalent of 16,000 water bottles, in less than one month.

Londoners can also access free drinking water from more than 2,500 cafes, shops and businesses offering free tap water.

Khan said: "With plastics polluting our oceans and causing untold harm to life in our rivers and waterways, it's vital that we all make changes to reduce plastic waste.

"Our network of water fountains will help people refill on the go and become much-loved additions to our public spaces, stations and busy areas of the capital," he said.
