The first two tap water fountains are already up and running near the Hanwell Clock Tower and Melbourne Avenue in Ealing in the biggest single-use plastic reduction initiative of any UK city, with more being fitted throughout this summer.
According to Thames Water, over the coming weeks water fountains will be unveiled in a number of areas including Camden, Greenwich and Southwark. Each fountain has been topped with a distinctive blue water droplet so will be easy to spot for anyone wanting to fill up.
Steve Spencer, chief operating officer at Thames Water said: "London’s tap water is world class and we’re celebrating this by building a network of water fountains so it’s even more accessible to people on the move."
Locations of the fountains will be displayed on Google maps and there will be promotional posters on bus stops and other advertising sites near every fountain from mid- August until the end of September.
Each fountain will undergo regular safety and quality inspection by Thames Water engineers, the company said.
