THE SEWER SYSTEM AGAIN
SURVEYOR MULLENNEY'S RE-
JECTIONS TO TT.

TO the sewer system planned pS MN
and adopted by the Board Of trustees
and the report was referred TO the
Sewer Committee.
1t is as follows:
Sacramento Oct %, 1897.
The Honorable Board Of Trustees
Gentlemen: In accordance with your
resolution Of last Monday evening, L
herewith present a report in RELATION
to the objections made by your sewer
Committee to the plan for a sewer sys-
tenn, submitted for your consideration
on May 24th last.
Before replying to these special op-
1ections / wish to point out to those
who are Of the opinion that We re-
quire an entirely different system call
ed separate or small pipe" system,
for house drainage only, or so-called
modern and scientific" system, this
fact-that whatever kind of system we
have, surface and seepage water must
be lifted up by pumping in order TO
be disposed Of; Furthermore, ii can
not all be drained over the surface OF
the streets to the pumping plant, but
must be taken care of by providing
storm sewers at proper intervals.
It is a fact also that all house drain
age and sewage must be disposed of
by pumping, so that a common outlet
is required in this city, all drainage
must be discharged into the river and
the possibility Of the city being en-
Joined from so doing is very remote.
Therefore, there is no advantage in a
separate small pipe system, especially
in a city so fiat that volume is neces-
sary to acquire velocity of flow and
which would so complicate our system
of drainage as TO make il expensive to
keep in order. If storm water could be
drained eff by gravity through the old
Sixth-street canal there would be some
reason in the small pipe theory. But
whether we have a small pipe system
or not, storm water sewers are required,
and the plan submitted provides for all
drainage.
The objections of your committee
made in their report of July 9th I viii
consider in proper order as follows:
First-Objection is made to proposed
extension of S-street main beyond
Twentieth street, on account of "Sut-
ter Terrace" hill, between Twenty-first
and Twenty-second streets, of which
a profile is here presented. The pro-
file shows the deepest cut to be %
feet and only for a distance Of about
200 feet, the elevation rapidly decreas-
ing at either end. This depth is only
111a feet greater than at Front and S
streets, where much seepage water was
encountered. / infer from the commit
tees report that it is proposed to con-
struct the main sewer north on Twen-
tieth street to n street, thence to Twen-
ty-ninth street; also construct a me n
sewer on Seventeenth street to V,
thence to Nineteenth street, thence to
X thence east to city limits
I wish to inform your board that
hard pam" or bed rock exists on n
street throughout, whereas on "Sutter
Terrace molding sand is found be-
meath the crust and is easily exca-
waited. Further on in this report is
given a comparative cost Of making
this change.
Second-The committee proposes to
reconstruct the sewer in alley, Front
and Second streets, from NJ street south
and extend through r street to S street.
This is not necessary for only two
blocks Of cement pipe can possibly need
to be replaced, and when the Third
street sewer is extended south to S
as provided in the plan, there will be a
free outlet for this alley sewer.
Third-The suggestion to extend the
Third street sewer from R to is al
ready provided for in the plan.
Fourth-The extension of the Seventh
and Eleventh street sewers would be
an unnecessary expense, as these sew
els viii have q free outlet when the
Ninth street sewer is extended from r
to S, which is provided for in the plan
Fifth and sixth-The construction of
new sewers in Eleventh street, from B
to L streets, and Fifteenth street. from
B to S street, will not be needed after
the Ninth and Thirteenth streets sew
ers have been constructed with larger
diameters, greater depth and greater
fall, as provided in the plan.
Low points on Fl at Eleventh or Fif-
feenth streets may be drained by catch
basins connecting with Sin. pipes to
the Thirteenth street sewer. South OF
n street the seventeenth street sewer
Is or large diameter, requiring a large
volume of drainage to give velocity
of flow. therefore, a sewer. in Fifteenth
street would be more of a detriment
than benefit. as it would divide This
volume of drainage. All complaints
from bad odor from this sewer will
cease when the flushing system pro-
vided for in the plan is adopted.
SeYenth-The recommendation that
sewers be constructed on Twenty-fifth
and Iwenty-ninth streets. from B to
n streets, conforms. of course. to the
first suggestion Of the committee that
main sewer be constructed on n
street.
Eighth-The proposition to extend
sewers south of street in alley. Front
and Second, Third Sixth, Ninth. Elev-
enth and Thirte@nth streets, is covered
by the provisions of the plan, which
shows sewers on Second, Sixth. Ninth.
Thirteenth and Seventeenth streets of
ample capacity for the demands which
may be made on them.
l estimate the proposed change Of
going around Sutter Terrace as fol-
lows:
Constructing main sewer on
INenueth street, from street
@ north to N street, increased
cost OF 4z-inch brick sewer over
z4-lneh pipe at 81 so per foot. So $50 90
increased cost of enlarging
proposed Seventeenth street
sewer, Il blocks at so cents per
