DUMBO - Water fountains are popping up around New York City to keep residents hydrated.

The Department of Environmental Protection's Water-On-the-Go program, which started four years ago, brings portable water fountains to outdoor spaces across the city. The department places fountains in parks, pedestrian areas and public plazas throughout the summer.

Each fountain has six faucets offering city tap water to New Yorkers.

Residents can find water fountains by using the "NYC Water" smartphone app or by visiting the Department of Environmental Protection's website.
