On a bad day, like after a heavy rain, the neighborhood located northeast from Owl’s Head Wastewater Treatment Plant here in Bay Ridge smells like a large outdoor public bathroom.
Residents have been complaining about for the last five decades, but to no avail.
The city’s Department of Environmental Protection acknowledges the problem, though it has been unable to make the smell go away.
In theory, the stench in any wastewater treatment plants is caused by the degradation of waste, and inadequate system to separate solid waste from which the smell leaks and combined sewers for rain and wastewater.
In the case of the Owl’s Head, which is located on 69th Street and Pier and which takes in 90 to 100 million gallons of sewage every day, the problem, experts say, is the solid waste separation system and the combined sewers for wastewater and rainwater.
Last summer, at a Community Board 10 meeting, the agency promised a smell-free summer.
Vincent Sapienza, the agency’s assistant commissioner, explained at the meeting that with the help of private consultants his agency had identified the smelliest parts of the plant and had placed covers on tanks, adopted a new carbon filtration system, and sealed windows at the thickener section.
But when heavy rains hit this stately neighborhood of two-story houses last August, the smell was stronger than ever.
“I remember coming home and thinking the dog went everywhere inside the house,” said one Shore Road resident.
The Bay Ridge Ink checked with experts, Kartik Chandran from the Columbia University’s School of Earth and Environmental Engineering and Vincent Ettari, a private consultant. Both said that there are solutions but they could be costly.
They suggested installing a separate storm drainage system to replace combined sewers, covering the plant, and employing bioscrubbers to get rid of volatile contaminants.
Last week, Sapienza told the board that his agency had launched a $37 million reconstruction project to get rid of the stench by January 2011.
Residents say there were thrilled at the news, but added that it does not mean much for them since their neighborhood will remain smelly for the next three years.
So, until then, people like Sayyid Samah will keep waiting for “the good days” to open a window.
“Those are the days when we breathe clean fresh air,” Samah said, as he walked after his two-year-old son Adam, along the fishing pier on a recent sunny morning. “Instead of the smell of sewage and crap that you smell around here.”
