And he thought the water in Manhattan was bad.

The delicate palate of Joaquin “El Chapo” Guzman — who had once requested bottled water behind bars — is in for a rude awakening once he gets to supermax prison in Colorado.

The iron-clad fortress in Florence has no shortage of commissary goodies ranging from the standard prison fare of ramen soup and cereal to pitted prunes and trail mix. But the Mexican national may be dismayed to learn his beloved enchiladas are nowhere on the menu.

Instead, he can feast on jalapeno refried beans for $1.70 — a steal! — paired with a $3.50 pouch of Brushy Creek beef barbacoa, $1.10 white rice and Pesos flour tortillas, which go for $2.30 for a 12-pack. And a squirt of picante sauce will set the Forbes billionaire back by 90 cents.

At trial, the pint-sized druglord’s live-in secretary testified that he pined over Swiss enchiladas made by his beauty-queen wife, Emma Coronel Aispuro, though he also preferred his mom Consuelo Loera’s version of the traditional dish.

On Wednesday, Guzman was sentenced to life plus 30 years for his role as the head of the lucrative Sinaloa cartel.

Sources told The Post that he’s headed for the federal lockup in Colorado, known as the “Alcatraz of the Rockies.”
