The new Whitney Museum is showing a Flushing side — big time.

The Meatpacking art mecca that only opened in May 2015 has managed to generate a titanic water bill and is already behind on payments.

The bill, including interest, had grown to $208,964 as of Sunday. According to city records, no payment has been made in the past 12 months.

By comparison, lawn watering and the nearly 50,000 fans who attend Yankee Stadium games, many of them swigging beer and soda, have generated a water bill of $353,000 — and it’s up to date.

Whitney director Adam Weinberg said last year the new $422 million museum hoped to double the 340,000 in annual attendance at its previous building on the Upper East Side. It has tripled its numbers in its first four months of operation, equating to some 20,000 people per day — and obviously a lot of toilet flushes.

The former uptown property, now operated by the Metropolitan Museum of Art as the Met Breuer, also has a late water bill, but that is a mere trickle of just $4,453, plus a late fee of $89. Two other payments totaling $1,997 were made in the past year.

The Whitney is entirely tax exempt, which equates to a savings of some $3.6 million per year.

No one at the Whitney returned requests for comment.
