Town of Vienna Water Treatment Plant

Vienna, Maryland

RAUCH inc. was selected by the Town of Vienna to write a preliminary engineering report (PER) to evaluate and recommend solutions to upgrade the Town’s water treatment plant, well, and disinfection system. The PER was funded by U.S. Department of Agriculture (USDA) Rural Development. Specifically, the report examined corrections to water system deficiencies within the water distribution system and methods of eliminating both realized and potential water quality and health issues facing the Town’s water supply. The completed PER/ER report offered several recommendations including discontinuing use of two unconfined wells along Elliot Island Road and replacing them with new wells in a confined aquifer. The recommended confined aquifer is lower in iron and other contaminates thereby reducing the amount of dosing required to remediate the Town’s water.

For more consistent water quality, we recommended that the water treatment plant be moved closer to the Town allowing for more uniform water treatment and dosing levels. We identified a location adjacent to the existing water tower within town limits as the best site. Finally, we recommended that the proposed water treatment plant be outfitted with the necessary treatment equipment and chemical treatment systems to address the lesser contaminates in the water drawn from the new wells. Additionally, the control room within the new treatment plant would be separated from the treatment and filtration equipment by putting each aspect of the water treatment in a structurally separate room or separate but adjacent building.

RAUCH, inc. applied for capital funding on behalf of the Town through the Maryland Department of the Environment’s (MDE) Water Quality Revolving Loan Fund (WQRLF). The grant was successful and MDE funds were awarded in 2021.
