Bowman Water Practice outlines crucial upgrades for Dahlgren Wastewater Treatment Plant

King George County officials are taking significant steps to address critical upgrades at the Dahlgren Wastewater Treatment Plant, following a detailed presentation by Bob Crowlander, a seasoned expert in wastewater management. During the meeting on March 4, 2025, Crowlander outlined essential recommendations aimed at enhancing the facility's infrastructure to meet stringent environmental standards.

The urgency for these upgrades stems from the plant's aging infrastructure and the need to comply with nutrient limits established under the Chesapeake Bay initiative. Over the years, the county has faced challenges in meeting these standards, leading to financial penalties and the necessity to repay Water Quality Improvement Fund (WQIF) grants. Crowlander emphasized that without immediate action, the facility risks failing to meet its effluent permit limits, particularly concerning nitrogen and phosphorus levels.

Key recommendations from Crowlander's assessment include a comprehensive evaluation of the plant's mechanical and electrical systems, as well as its structural integrity. He highlighted the need for modernizing outdated technologies, such as the aeration system, which currently relies on spinning discs that are inefficient and difficult to control. Upgrading to more effective aeration methods could significantly improve the plant's performance.

Additionally, Crowlander pointed out that previous retrofitting efforts, such as the installation of media intended to enhance nitrogen treatment, have not yielded the desired results. He called for a reevaluation of these solutions to ensure they effectively contribute to meeting regulatory requirements.

The meeting also addressed the importance of asset management and the need for a strategic plan and budget to implement these upgrades. As the county moves forward, officials will need to prioritize these recommendations to secure the reliability of the Dahlgren facility and protect the local environment.

In conclusion, the discussions at the meeting underscore the county's commitment to improving wastewater management and ensuring compliance with environmental standards. The proposed upgrades are not only vital for regulatory compliance but also for safeguarding the health of the Chesapeake Bay and the community at large.
