McMillan Backwash Pump Replacement

The Washington Aqueduct, operated by the USACE Baltimore District, supplies drinking water to Washington, DC, and parts of Northern Virginia via the Dalecarlia and McMillan Water Treatment Plants. At McMillan, aging infrastructure within the backwash system, critical to filter cleaning operations, has led to issues such as media loss, cavitation, and water hammer. These problems stem from outdated flow control, air relief limitations, and equipment failures. This project improved the reliability and performance of the backwash system by upgrading key components, optimizing flow control, and replacing undersized air relief valves. Our team is providing inspection, evaluation, design, and construction support to enhance operational efficiency and mitigate system stresses during filter maintenance cycles.
