Sewage Spill Clean-Up
We now know how much raw sewage flowed into the French Broad River yesterday.
A valve blew up yesterday at the Metropolitan Sewerage District Waste Treatment plant.
Engineers say as a result, 6 million gallons of untreated sewage dumped into the river.
Today they've covered the area that discharged the most sewage with a thick coating of mulch.
Yesterday the scene here was much different, as millions of gallons of sewage made a gyser at the manhole.
It covered a wide area below the MSD headquarters parking lot.
Woodfin Riverside Park is closed because of the same problem there.
The backup in the lines forced sewage to overflow manholes here, covering parts of the park with untreated waste.
MSD workers hosed off walking paths and spread straw to soak up the sewage yesterday.
Engineers aren't sure when they can re-open the park.
They say the flow lasted just over 6 hours, and during that time more than a billion gallons of river water passed by the plant, that's a dilution of about one to 200.
Because of the weekend rainfall the river is much higher than usual and they're hoping test results will show a less concentrated level of pollution.
Water samples were taken yesterday and sent to state labs.
Those results are expected to be announced later this afternoon.
The MSD could be fined for yesterday's river pollution.
