Sorry, folks, if you wanted to tour a wastewater treatment plant for Valentine’s Day, you may have to settle for a White Castle reservation instead.

The city’s Department of Environmental Protection announced yesterday that reservations were open for its annual Valentine’s tour of the Newtown Creek Wastewater Resource Recovery Facility in Greenpoint. But tickets for the Feb. 9 tours sold out within an hour and a half. Poooo! Boooo!

According to a press release, the tours will offer an overview of the process that treats the wastewater of some 1 million local residents (because not all New Yorkers use a “shit bucket” a la last night’s episode of Broad City). And now the romantic part: Lucky visitors will get a view of the skyline from a 120-foot-high glass-enclosed walkway atop the 51-year-old facility’s iconic digester eggs. Evening visitors might even get to see the bonbon-esque “eggs” illuminated in romantic boudoir lighting:

Visitors are advised to wear closed-toe, flat-soled shoes. I don’t think I have to tell you why.

If you missed out this time around, stay tuned to the DEP’s Twitter page for information about the next tour. There are just three per year.
