Sewage overflowing from broken pipe causes traffic delays, odor at Clara Barton Parkway

Drinking water is not affected but people might notice an odor in the area, according to DC Water.

A sewage pipe broke near Clara Barton Parkway in Montgomery County, Maryland. News4’s Juliana Valencia and Melissa Mollet shares how it’ll impact traffic.

A broken sewage pipe is leading to traffic for commuters in Montgomery County on Tuesday morning.

The right eastbound lane of Clara Barton Parkway past the Capital Beltway is closed, the Metropolitan Area Transportation Operations Coordination program said. There is no timeline as to when the pipe could be repaired. DC Water says commuters should expect delays and consider taking alternate routes.

There is an odor in the area.

Crews saw wastewater was flowing from the Potomac Interceptor sewer line in C & O Canal National Historical Park on Monday night. Crews are working to contain the overflow and assess damage.

"DC Water has mobilized its crews and contractors to mitigate the overflow and keep it contained as much as possible so they can assess the damage and begin repairs," DC Water said.

DC Water Senior Manager of Communications Sherri Lewis said crews created a bypass in the Potomac Interceptor upstream from the pipe that will divert the flow into the C & O Canal.

"It'll essentially damn it and store it to prevent as much as possible from going into the Potomac River," Lewis said. "We will have pumps that will pump it back into the Potomac Interceptor further downstream away from this collapse."

Trails and parking near the parkway could be affected. Residents who live in the area might smell an odor from the sewage.

The pipe's overflow is expected to reach the Potomac River. Drinking water won't be affected, DC Water said.

"It is important to note that DC Water's drinking water system is separate from the wastewater system and is NOT affected by the overflow. The overflow is downstream from the Washington Aqueduct’s intakes at Great Falls," DC Water said.

The Potomac Interceptor sewer line carries about 60 million gallons of wastewater daily from areas near Dulles International Airport.

DC Water says untreated sewage could contain pathogens that cause various illnesses, ranging from E. coli to hepatitis. If you or someone you know comes in contact with the sewage, DC Water says to do the following:

    - Leave the area immediately.
    - Wash exposed skin thoroughly with soap and clean water.
    - Disinfect any affected areas or items.
    - Do not consume food or water that may have been exposed.
    - Seek medical attention if symptoms occur.
    - Report exposure to DC Water at (202) 612-3400.

Cold weather is creating equipment and operational challenges at the Potomac Interceptor break, and full containment isn’t reached yet. Crews and contractors continue running the bypass system day and night, and additional pumps are being installed to increase capacity at the site.

Terrible incident.  Glad some headway is being made.  Infrastructure is in serious need of updating.

From Potomac Riverkeeper: For right now, DC Water’s efforts to contain the sewage spill in the C&O canal seem to be effective. However, Dean’s monitoring at the site yesterday showed some sort of flow entering the river though it is unclear where it is coming from.

Evan is back on site today to conduct more water testing to see if we observe a change in E. Coli levels since the containment was implemented.
This is not an ideal situation and this spill should have never happened. Sewage pipe infrastructure should be closely monitored and regularly maintained to prevent public health disasters like this.

And to date, there still have not been any public health advisories implemented to warn people to stay away from the river.

We will continue to keep you updated as often and as best as we can. We expect to know the test results of water samples taken last week with UMD sometime this week and will communicate results ASAP.

Data centers (as ugly as they are) are private and pay taxes.

Infrastructure is municipal and requires taxes for upgrades and fixes.

Yes.  I meant cost of water and electricity included as the data centers use much more of that.  Maybe it is spread out fairly, but I think not.

Do data centers pay for excess electricity and water costs?
Data centers do not directly pay for excess electricity and water costs. Instead, the increased demand for electricity and water from data centers is met by upgrading the existing infrastructure, which is then shared among all customers. This means that while data centers contribute to the overall increase in electricity and water costs, the actual costs are borne by the public through increased utility rates.

On the campaign trail for VA governor, Spanberger said the following about data center electrical use and surrounding community and residents energy bills:

MANASSAS — Abigail Spanberger, the Democratic nominee for governor, says she wants data centers “to pay their own way and their fair share"  of rising electricity costs to serve them.

But her actions a month after she was inaugurated was to increase energy costs to local Fairfax residences by as much as 16% per unit used.

I can only see higher energy costs in the future to the community and residents based on the number of new data center constructions I see springing up locally

Good news is my Dominion Energy stocks were up over 30 percent last year.

The Question: Will you acknowledge the science that shows the river is recovering, or is the "alarm" just better for your business?

I'll let you know after I fish it a couple times

Someone was out fishing the Potomac recently

Sad to see.  Dude wipes are really popular now.  Sewage systems were not built for this stuff.
