Washington, DC, September 29, 2026 —

WSSC Water has issued a call for water conservation among its customers in Montgomery and Prince George’s counties. The request comes as a direct result of a power outage affecting the Potomac Water Filtration Plant.

The Potomac Water Filtration Plant is a critical facility responsible for treating and supplying water to a significant portion of the region. A disruption in its power supply directly impacts its operational capacity, potentially leading to reduced water pressure or availability. WSSC Water has not provided specific details regarding the cause or estimated duration of the power outage.

In response to this operational challenge, WSSC Water is urging residents and businesses in the affected counties to reduce their water usage. This conservation effort is essential to ensure adequate water supply for essential services and to manage the plant’s output during the outage.

Specific instructions for water conservation were not detailed in the initial announcement. However, typical water-saving measures include:

  • Limiting outdoor watering of lawns and gardens.
  • Reducing the duration of showers and baths.
  • Running dishwashers and washing machines only when full.
  • Fixing any leaking faucets or pipes.

The contractor responsible for the power supply to the plant was not identified. Similarly, the timeline for restoring full power and normal operations at the Potomac Water Filtration Plant has not been provided. WSSC Water has stated it is working to resolve the issue and will provide updates as more information becomes available. Customers are advised to monitor WSSC Water’s official communications channels for further guidance.
