Annapolis Water Reclamation Facility

The Annapolis Water Reclamation Facility (WRF) is a wastewater treatment plant jointly owned by the City of Annapolis and Anne Arundel County. The County is responsible for the operation and maintenance of the facility. The facility employs an advanced activated sludge process with nitrification/denitrification for Enhanced Nutrient Removal (ENR) level treatment. The plant consistently achieves a high-level of nutrient removal, which protects the Severn River and Chesapeake Bay. It is also an award winning facility, recognized by National Association of Clean Water Agencies (NACWA) for perfect permit compliance since 2016.

 

 


Facility Upgrades

There are several capital projects to upgrade and improve the Annapolis WRF. These upgrades to aging infrastructure are being phased and sequenced to avoid treatment process disruption. For more information on these projects please visit the County’s Capital Improvement Project website.

 

Odor Control Project

The County acknowledges the close proximity of the existing plant to its surrounding neighbors.  The County is conducting a comprehensive odor evaluation, including monitoring, data collection, data analysis, and air dispersion modeling to identify sources of odors and potential capital improvements needed to address them.  The performance of existing odor control facilities are also being evaluated as part of that study. From this evaluation, a recommendation for upgrades or process changes will be provided.

A capital project has been created and the County has initiated the process of contracting a design engineer to proceed with the design of the recommendations once the odor evaluation is complete.
