WATER DAILY USED
IN D, c. PER|L0USLY
NEAR SAFETY MARK
1920 Consumption Of &C.,
10000 Gallons a Day Ex-
Ceeded Previous Year.

Washington consumed an average
during the fiscal year ending June 80.
coming perilously near the 6S,000.000
gallons set as the safe daily ca
pacity" of the District water system.
The daily average consumption for
the previous year was 65,260,000
gallons
This information was contained in
the annual report of Col. Max c.
Tyler. engineer officer in charge of
the District water supply system,
made public today. The report was
submitted to Gen. Beach, chief of
engineers.
Working on the assumption that
figures present a more graphic pic
ture of the need for conserving water
in the District than an elaborate
statement, Col. Tyler submitted his
table of statistics on the water sit
uation without comment
147 Gallons, Daily Capita.
Based on a population of 455,42s
for the District, Col. Tyler's report
shows that the daily per capita con-
sumption for 1920 was 147 gallons. as
against 156 gallons for the previous
fiscal year. The maximum capacity
of the conduit is estimated at 9O,-
100000 gallons and of the filtration
plant 90,000.000 gallons with all
pumps in service.
While the per capita consumption
of water shows a decrease over the
fiscal year ending June 80, 1919. some
idea of the drain on the system by
the big government establishments is
shown by the statement that an aver
age daily consumption of 2.653.500
government printing office; 1.054,500
gallons by the Washington navy yard,
1.264.7O gallons by the bureau of en-
craving and printing. $4,000 gallons
by the State. War. and Navy build
ing. 523,400 gallons by the Depart
amounts by other federal and munich
pal buildings.

ter per twenty-four hours during the

May, when the average consumption
Iper twenty-four hours was 63,59O,OOO

Though there. was one day in Decem-
Der when but 54.750.000 gallons were
Iconsumed and one day in May, when
but 54,320,0O0 gallons were consumed.
The cost of operating the filtration
,plant during the past year is stated
at $5.75 per million gallons of water.
