About
The wastewater system is divided into ten service areas. The Bureau operates Water Reclamation Facilities in nine (9) of those areas and has ten connections with three other jurisdictions (Baltimore County, Baltimore City, and Howard County).
The current capacity of the system is 47.6 MGD, which is adequate to meet the average daily demand.
