Another 41,000 gallons of sewage has overflowed into the Jones Falls, the Department of Public Works reported today.
The latest wastewater spillage occurred in the “structured overflow” pipe located behind 428 East Preston Street, according to DPW.
The overflow, discovered on Friday, continued through the weekend until it was curtailed this morning.
“Bypass pumps stopped the flow around 11:00 a.m. today,” a DPW email said, adding that none of the human waste spilled onto city streets.
The agency said the cause of the overflow “has not been determined.”
Sanitary Sewer Outfall #72, the site of this latest sewage release, is one of several structured overflow pipes designed a century ago to relieve pressure and prevent back-ups when heavy rainfall mixes with sewage and overwhelms the sewer system.
But this weekend’s overflow occurred during dry weather.
Could the cause have been a “fatberg”? DPW officials could not be reached late today to comment.
Last month, the agency attributed a sewage overflow of more than a million gallons below the Charles North neighborhood to a 20-foot-long lump of congealed grease and fat that had plugged a sewer main – a so-called “fatberg.”
Contractors hired by the city blasted out the rancid obstruction with high-pressure hoses and vacuum pumps – and warned residents and restaurants to stop putting cooking grease, baby wipes, dental floss and other clog-promoting substances into the overtaxed sewer system.
