Wastewater in the Potomac River
Date
Today we’re talking about the Potomac River and a collapsed sewage pipe.
The Potomac is a 600 km long river in the eastern United States—and the river that flows through the capital, Washington, D.C. Its course is quite impressive, and shortly before it flows into Chesapeake Bay, it widens to up to 13 kilometers.
The water quality in the river had been steadily improving in recent years. Although swimming and fishing are not yet possible, the development path has been promising.
In mid-January, a sewage pipe burst directly on the river. Its contents spilled untreated into the Potomac River just above Washington, D.C. for a good week. The affected pipe transports approximately 270 million liters of sewage per day.
The capital’s drinking water is not currently affected. However, higher concentrations of E. coli and staphylococcus bacteria have already been measured in the river. The nitrate pollution that has entered the river as a result is roughly equivalent to the amount that would be released into a river from a large sewage treatment plant in an entire year.
At the moment, the wastewater is being diverted and the hope is that a long-term solution will be implemented within 4-6 weeks. It is not yet clear when the population will be able to use the river again as usual. In addition, local residents currently have to cope with a strong odor nuisance.
Accidents like this remind us to keep searching for better solutions. Waterless toilets can significantly reduce the burden on wastewater systems and thus contribute to a more resilient infrastructure. We at ABEREUS are happy to support this approach.
