The following gives the boundaries
and description of each district in de

Sanitary District Nc. I.
Boundaries Of which are as fol-
lows:
beginning at ii point at the inter
section Of Higgins avenue ana the
Northern Pacific right way: thence
easterly along the Northern Pacific
right way to the center Of alley be
tween Madison street and Monroe
street: thence south along center line
of alley to line parallel to and 1870
feet south Of the south line
of Front street: thence west
erly along said line to the center
Of Higgins avenue: thence north along
the center line Of Higgins avenue 10
the place of beginning; comprising
about SOC lots go #. by 1870 TT, AN
approximate area If - acres.
The volume Of sewage to be carried
by the Higgins avenue main is csti-
mated In the following manner: or
the 500 lots in this district about 20
per cent are ut present considered as
business lots. and. Judging from the
location and present Indications. it ap-
pears advisable tn estimate that 10 per
cent of the area embraced within this
district Will, in reasonable time. de
velop into business property. provi-
sion has, therefore. been made in the
size. depth and general design tn meet
the probable future requirements.
Estimating 40 per cent as the future
business Iarca, covering hotels. room
ing blocks and mercantile establish
mants, We have 200 business lots
with business blocks ranging from one
to six stories in height. or an averag GO
of three stories. having Il total floor
space Of 10000 square feet each. Al
lowing $50 square feet to each occu-
pant would be equivalent to 81 occu-
pants per building. and the 200 lots
would mean n population Of 13.20a in
the business section of this district.
This estimated population may not
be reached for many years; on the
other hand. II is not at all unlikely
years. and the location and conditions
affecting this particular district seem
to justify the estimate herein made.
In the residence portion of this dis
triet we have so per cent. or 900 lots
$50 #. by 1870 IT., with an estimated
average of three occupants per iot. a..
800 population In the residence port ion
of the district, and IA total population
nf Ii,l0n in the whole of said district.
In calculating the volume of sewage
to be provided for. the water consnmp-
ton is used as "A basis. The consump-
ton of water in different localities va
rios to great extent and in cities of
the United States statistics record IA
wide range dependent upon location
and local conditions.
In the absence of recorded data in
the city OF Missonla, comparison is
made from other Montana cities. As
an exampel of this the per capita con
sumption in Great Falls. for all pur-
poses. ranges from 60 gallons per day
in winter to go gallons in summer.
irrigation of bouievarded streets, parks.
lawns and gardens being Responsible
for the Increased consumption during
the summer months.
In addition To providing for the esti-
mated future population Of $4,000,
which Is probably the most dense pop
ulation that will occupy this area, an
increase in capacity Of the sewers of
this district has been considered adj
visahle for the accommodation of roof
drainage. which Is a factor that must
be considered.
"A, l,f

system: yet II viii he convenient. ana
in many cases necessary, to utilize the
sanitary sewers Ia carry a considerable
quantity of roof drainage In the husi-
ness section. plumbing for same having
heretofore been connected with the
house sewers. This can safely be done
within certain limits for some years
Ia come. depending upon the building
up of the district.
There is also planned storm
sewer ON Higgins avenue. to which
roof drainage should he conducted by
laterays through the alleys or by direct
connection when same is desirable or
becomes necessary to avoid nVertaNing
the sanitary sewers.
Also it must be borne In mind that
sooner or later the city may he obliged

II is. therefore. advisable Ia main

lent and economical means of disposal
