County Executive Leopold Announces Construction of Major Sewage Treatment Plant Upgrades

Projects will further reduce nutrient discharges and protect the Bay

Annapolis (May 6, 2010) - County Executive John R. Leopold today announced that the largest wastewater treatment plant upgrade project in County history has begun, aimed at reducing discharge concentrations of nitrogen into the Chesapeake Bay by 50 percent and phosphorus by 80 percent.

"Protecting our most precious natural resources is vital to the enhancement of our overall quality of life," County Executive Leopold said. "Proceeds from the Bay Restoration Fund are helping us upgrade our Water Reclamation Facilities and decrease the amount of harmful pollutants discharged into our waters that are basically choking the life out of the Chesapeake Bay."

The County will fund about $31.4 million of the $200 million cost of upgrading the Cox Creek, Broadneck and Annapolis plants out of its Utility Enterprise Fund, which comes from charges customers pay on their water and sewer bills. The majority of the funding comes from the Bay Restoration Fund, which is paid by County residents and customers throughout the State. Work began this week on Cox Creek, the largest wastewater treatment facility in the County that provides about 33 percent of our total capacity.

The Anne Arundel County Department of Public Works will add an advanced, innovative and state-of-the-art technology called membrane filtration to the wastewater treatment process. By adding membrane filters, we eliminate the need to construct more conventional aeration tanks and secondary clarifiers, and add effluent filters for an even higher level of treatment. This is imperative given the limited space of the Cox Creek Facility and it’s location that borders the Patapsco River and the close proximity to Constellation’s Brandon Shores Power Plant.
