Hist and Proj Operating Receipts FY 2011 2 17 2010 - DC Water

Anacostia and Rock Creek Park, and we have submitted a plan to EPA and constructed, Low Impact Development (LID) projects at
various DC WASA facilities.
At this time, we have completed a final draft of a Facility Plan for the Anacostia River CSO projects. The Facility Plan includes a
Summary Report and detailed implementation schedule. Under the consent decree, it was submitted to the Environmental Protection
Agency (EPA) in September 2008, and we are moving the Anacostia River CSO projects into design and construction in accordance
with the detailed schedule in the Summary Report.
Stormwater in the District of Columbia remains a challenge for District policymakers and for the agencies with the responsibility for
managing an array of program activities as well as maintaining and improving the infrastructure (catch basins, underground facilities,
pump stations, etc.), some of which are over 100 years old. DC WASA management and staff have been engaged in extensive
discussions with the District over the last several years regarding how responsibilities for a variety of storm water-related functions
are divided among District agencies. DC WASA no longer serves as Administrator for the District's municipal separate storm sewer
system (MS4) NPDES permit fund. This was transferred to the D.C. Department of the Environment (DDOE) in FY 2007. DC
WASA, however, does continue to collect the MS4 fees and transfers those funds to the District on a quarterly basis. Under an MOU
with DDOE, DC WASA also cleans catch basins once a year.
At Blue Plains, we provide wastewater treatment services to approximately two million people in our service area, including residents
of the District of Columbia and significant portions of Montgomery and Prince George's counties in Maryland, and Fairfax and
Loudoun counties in Virginia. Wastewater treatment includes liquid process facilities that provide treatment for both sanitary
wastewater flows and peak storm flows originating in the sanitary and combined sewer systems, respectively, along with solids
processing facilities that treat the residual solids removed by the liquid process facilities. Blue Plains is rated for an average flow of
370 million gallons per day (MGD), and is required by its National Pollutant Discharge Elimination System (NPDES) permit to treat a
peak flow rate of 740 MGD through the complete treatment process for up to four hours, and continuous peak complete treatment
flows of 511 MGD thereafter. The Plant treats these flows to a level that meets one of the most stringent NPDES discharge permits in
the United States. Additionally, up to a 336 MGD stormwater flow must receive partial treatment, resulting in a total plant capacity of
1,076 MGD. A few key areas of measurement for the treatment process are provided below and demonstrate that DC WASA
exceeded all regulatory requirements in FY 2009.
