The main source of water supply of the Sanitary District is the
Patuxent River, which has been impounded by the construction of
a dam near Brighton in Montgomery County. There has been con-
structed another dam on the same river near Laurel in Prince George's
County. With the completion of this dam, the Washington Suburban
Sanitary District has an assured yield from the Patuxent River of
slightly over 40 million gallons daily. The Commission also obtains
a portion of its water supply from the Northwest Branch of the
Anacostia River, which water is treated in a rapid sand filtration
plant at Burnt Mills. It has a third source of supply from deep wells
at Forest Heights in the southern portion of the District. This under-
ground supply will yield at present 1.4 million gallons daily.

At the present time sewage is disposed of by discharging it into
the District of Columbia sewerage system and treating it at the
Anacostia Sewage Treatment Works of the Commission near Bladens-
burg, Maryland. Negotiations are under way with the District of
Columbia whereby all the sewage of the Sanitary District will be
treated at the District of Columbia Sewage Treatment Plant at Blue
Plains.

Refuse is disposed of by means of an incinerator located at Lyttons-
ville and a sanitary landfill at Fairland in Montgomery County and
an incinerator at Bladensburg in Prince George's County.

The construction operations of the Commission are financed from
proceeds of bonds. These bonds are retired with funds from several
sources. The general construction bonds are retired by front foot
benefit charges and ad valorem taxes. Bonds for major water and
sewer construction are retired from water consumption and sewerage
usage charges respectively. Refuse incinerator bonds are retired from
receipts of the refuse service, and storm water drainage bonds are
retired from ad valorem tax receipts.
