PHILADELPHIA -- A city spokewoman this week issued a statement scolding residents who held a Dumpster pool party on Cedar Avenue over the weekend, and warned others not to try it.

Yes, you read that right: dumpster pool party.

"We are not screwing around, Philly," Karen Guss said in a press release posted on BillyPenn.com. The website broke the news about the Cedar Avenue block party featuring a dumpster filled with water from a city fire hydrant.

Before you get all grossed out, party people Justyn Myers and Jake Long told BillyPenn that they power-washed the rented Dumpster before jumping in. They also spruced it up with a few pool noodles before tapping the hydrant.

Guss told NJ Advance Media that the city is concerned about the hype about the Dumpster pool and really wants to convince residents they're a bad idea.

She said they haven't caught any other copycats. But then, it hasn't been as hot as it was this weekend.

"In view of the City's commitment to public health, safety and basic common sense, we will not issue permits for block party dumpster pools," Guss said in her statement. "And while you would think this decision would not require an explanation, three days of press requests have proven otherwise."

Fire hydrants serve one, very important purpose: to provide water in case of fire. If you see an open hydrant, call @PhillyH20 215-685-6300 — Philadelphia Fire (@PhillyFireDept) August 3, 2016

She explained that tapping the city hydrant could limit the amount of water available if a fire broke out in the neighborhood. The high pressure water coming out of the hydrant could also knock someone into traffic or, if opened or closed too fast, could cause the water main to break, she said.

No more block party permits will be issued for the 2400 block of Cedar Avenue, she noted.
