Rockville’s water once again met or exceeded all federal water quality regulation limits, the city’s Department of Public Works said in the Annual Drinking Water Quality Report released July 1.
The city’s water treatment plant, on the banks of the Potomac River, serves 70% of Rockville, or approximately 13,500 accounts and 52,000 community members. The Washington Suburban Sanitary Commission serves the remainder of the city.
The past year saw the completion of several major parts of a plant upgrade project that began in 2021. This included the replacement of aged electrical systems and components that provided primary power to the plant and updates to the main building’s roof, HVAC system and workspaces that had remained unchanged since the plant’s opening in 1958. Network cybersecurity improvements and a chemical feed project to replace chlorine gas with sodium hypochlorite (liquid chlorine) are ongoing.
The plant improvements enhance system reliability and community safety, and provide safer workspaces for employees. Plant operators monitor water quality to ensure chlorine and corrosion control, preventing lead and copper in distribution pipes from leaching into drinking water.
Rockville 11 offers an inside look at the state-of-the-art technology, treatment processes and skilled staff who deliver high-quality water to Rockville households:
As part of Lead and Copper Rule Improvements by the U.S. Environmental Protection Agency, Rockville is taking inventory of all water service line materials on public and private property. The city is mailing surveys to water customers to request assistance in its inventory efforts.
No lead service lines have been identified within the city’s system. Rockville will prepare a lead service line replacement plan and review corrosion control treatments based on EPA rule revisions. Learn more at www.rockvillemd.gov/lcrr.
