Washington Suburban Sanitary Commission voted to upgrade its Potomac Water Filtration Plant over the next two years at a cost of $2 million.
Last week, WSSC agreed to award a contract to William Scholosser Co., Inc., of Hyattsville for various maintenance projects.
The Potomac plant is the larger of WSSC’s two filtration plants. It supplies an average of 112 million gallons of water daily and serves about two-thirds of WSSC’s customers in Montgomery and Prince George’s Counties.
Its Patuxent plant supplies about 72 million gallons of water per day.
The Potomac plant was last upgraded between 2002 and 2010 at a cost of $127 million. That project included filtration treatment enhancements, electrical equipment upgrades and new disinfection technology, including advanced ultraviolent disinfection.
The new $2-million contract “is more of a maintenance contract,” explained Luis Maya, WSSC senior public communication specialist.
During the next two years, when the Potomac plant needs “operational improvements,” the money to pay for the work will come from the new $2-million contract.
Some projects that will likely be undertaken include replacement of valves, filter screens and other plant maintenance identified as necessary by WSSC staff.
“This contract and recent plant upgrades highlight WSSC’s commitment to investing in its water infrastructure,” Maya said.
Maintenance and upgrades are part of “WSSC’s continued commitment to delivering safe and reliable water to the 1.8-million customers in Montgomery and Prince George’s Counties,” Maya said.
The Patuxent plant also underwent similar upgrades, which were recently completed in October. This plant now also has an ultraviolet disinfection system, which was part of the $65 million upgrade.
According to WSSC’s website, ultraviolet disinfection utilizes light in the UV spectrum to make sure certain microbial pathogens are harmless — adding an additional level of protection to its drinking water.
