Wastewater

Rivanna operates four water resource recovery facilities (formerly called wastewater treatment plants) with a combined capacity of 15.7 million gallons per day (MGD). We handle all wastewater flows from City of Charlottesville and the Albemarle County Service Authority’s municipal collection systems to RWSA’s interceptor system of pipes and pump stations to our recovery facilities. We do this efficiently, economically, and with the environment in mind.

Our largest facility (shown above) is our 80-acre Moores Creek Advanced Water Resource Recovery Facility, which handles all of the urban area and Crozet wastewater.  With over 110,000 residents, as you can imagine this is no small task.  Over 30 highly skilled, trained and licensed staff operate and maintain the treatment processes and regulatory compliance with our federal/state discharge permits.  Learn more about the wastewater treatment process here and more our wastewater operators here.

In 2012 we invested in a large nutrient reduction program which goes above and beyond all state and federal nutrient requirements, so that we actually earn revenue through the Virginia State Nutrient Credit Exchange Association.

Current challenge

History, topography, and proximity to Moores Creek have combined to bring us the challenge of operating a large scale wastewater plant in close proximity to neighborhoods and the hospital.  In our effort to be good neighbors, we have embarked on an extensive $9.3 million dollar odor control project to address this issue. We are putting in state-of-the-art facilities including the construction of an odor control unit with technologically advanced biological “scrubbers” which “vacuums” the air space, treating and neutralizing the odor compounds. In the end we hope to eliminate the most egregious odors, keeping them within the facility boundaries. For more about the project go to our Odor Control Project page.

On average, we treat 10.1 million gallons per day of wastewater. Our largest day of wastewater treated in 2016 was 22.2 million gallons . We maintain 704 manholes throughout the area.
