The fountain "network" is part of a collaboration between the city and business partners to provide free drinking water, in a bid to help citizens use refillable bottles and lower the amount of single-use plastic bottles sold. /VCG Photo

The average Londoner currently buys more than three plastic water bottles every week, according to figures from ZSL #OneLess campaign, which amounts to 175 bottles every year per person. /VCG Photo

The fountains are made out of rust-proof, high-quality, marine-grade stainless steel, with built-in freeze protection to ensure that they are operational in cold winter. Over 100 further water stations will be installed before the end of 2020. /VCG Photo
