With temperatures feeling like over 100 degrees, the City of Mount Vernon is going old school to try and keep residents cool.

The Mount Vernon Fire Department is opening 10 fire hydrants across the city.  To make it safe for kids, sprinkler heads are added to the hydrants.

Mount Vernon Deputy Fire Chief Juan Peralta tells News 12 that they will typically open hydrants once the thermometer hits 85 degrees.

"One of the reasons why we do this is that we only have one pool in Mount Vernon, and a lot of times it becomes overpopulated and over dense and filled to capacity."

Peralta says the hydrants will usually stay on from 11 a.m. until 8 p.m.
