lntercepting Sewer.
The last item of the estimated cost
was for an intercepting sewer. The
report has this to say of this sewer:
The intercepting sewer is a possible
extension of the Brady creek sewer TO
4 point below the pumping station. 1t
would be built only in case objection
was raised 10 the discharge of water
from sewers into the river above the
dam. AS storm water would injure
nothing at that point except, possibly.
the ice crop: and as the sewers are un-
likely 10 be discharsing at the time of
the ice harvest. the need Of its con-
struction IS considered remote"

Utiiizes Present Sewers.
The report says the system has been
planned so that there will be sufficient
velocity so that few catch
basins will have 10 be built The sys-
TEN also provides for further devel-
opment by extensions as the growth of
the city demands il. The few storm
sewers now in existence are utilized in
the system.
The report also makes recommended
tons as TO materials and COMPARE
son of them as to cost. etc Much
technical Information as to drainage
areas, the amount OF off flow from
given areas and the rate of flow. de-
tails essential 10 determining the size
Of sewers. are included
Car Establish Sewer Districts.
lhere are two or three ways in
which the city can build part or all Of
this complete system, which circum-
stances will force 1t to do at some time.
If not now. The law allows the city
10 establish drainage districts and as
sess the cost OF the sewers to the prop
erty in the districts. The plan pre-
pared has contemplated this in adva
and none of the districts or divisions
overlap SO no property would be as
Sessed for two sewers.
Another way is the city could issue
bonds for the project. and levy tax
TO take up the bond with a long per-
iod OF years. The report has not yet
been laid before the council so no ac-
ton has been taken on it, But the
Information is compiled in an under
standable form now. and will be useful
a. any time II Is wanted.
