est percentage of the river sewage |
was discharged. had length about five
miles and, with this short length, or |
head of water, according to the report |
the damage in ease ot Il heavy rainfall |
was done. Every one should know that |
If you add one-third more of sewage |
and an increased length or head of !
waterway, with no means of increas
ing the capacity of the outlet. you are |
decreasing the amount of pollution that |
will flow into the lake in the event of |
heavy rainfall. This is common sense |
the more you add to the source of
supply of the river. the less you will !
discharge into and from the river. II
with five miles and one-thlrd of the |
territory. there We're great pollution of
the lake. of course. with about twenty
eight miles added to the stream and
two-thirds more of territory, there will
be less.
This is precisely the reverse of the
other proposition. for 1t makes the
greater produce the less. Truly the
science of engineering has made re.
markable advance. when applied to the
drainage canal and its capability of dis
posing of the sewage of the city. 1t
has made the less absorb the effects
of the greater in one case, and has
made the greater supply produce a less
result in another instance
There is another point. insignificant

creased and the canal will do its al
legged work of taking care of the sew
age. Every mile of additional paved
streets with the now open land covered
by buildings. adds TO the water supply
per acre that will enter the sewer and
the river. and a. a matter of necessity.
the flow should increase. but the skill
Of the engineer has looked ahead for
this possibility by planning and build.
ing the canal to take care of the addi-
tional supply without any increase in
the gravity flow.
As n matter of fact. is the canal
built so that no increase of gravity
flow is possiblei If so. what dsposi-
answers none. Possibly the purpose of
deepening the river TO thirty feet is to
prevent back flow. II certainly must
have some object-probably to increase
the drainage. as any farmer having u
cesspool that he wanted To drain would
build his drain. and II II did not work
would at once proceed to lower the bot
of hi. al hAn
of water: or If he had tank supplying
his house with water, and the head was
not sufficient. he naturally would lower
the bottom of the tank. 1t is true this
j. contrary to the general practice but
u great many things In this wrOngfully
designated drainage canal appear, on
the face of the returns. to be contrary
