CATION, while 124 OF them object also 10 sew-
age irrigation In their vicinity.
Table No. 8 shows that five persons, owning
], ,O26 acres of land in the direction of Ballona
will ts Re the sewage for irrigation, crude or
Purified; six persons, ownink l,O2S1a acres,
will take the sewage for the dry season; no one
in that vicinity offers to take sewage during
the wet season. All six persons refused to
enter into contract with the city to take the
sewage at all times, while five use well water
for domestic purposes.
holders IN the direction of La Ballons, control
ling I'll acres, refuse to irrigate with sewage,
while twenty-one OF Them also object to sewage
irrigation in their vicinity. Most Of the land
is reported to be sandy or sandy loan
The conclusions which are resched from the
foregoing tables point Enthusiastically to the fol.
lowing facts:
First-That great portion of the lands lying
south of the city are suitable for irrigation pur
poses. This the commission can affirm from
personal inspection.
second-lhat an insufficient amount of land
is offered for permanent disposal of the city's
sewage.
.Third-That enough land is, however, avail.
able ior disposal during the dry season.
Fourth-That an insufficient mount OF sew
age would be accepted in winter.
These conclusions, together. with the expert
ence OPT obsned IN eisewhsre clearly show that
sewage on land fouth OF the city curing the
summer, but that In winter no demand exists
therefor.
The problem, therefore, requiring a solu.
tion, is the finding OF a practicable method
of disposing of the sewage during the winter
months.
In order to have some tangible data regard
ing the length Of time during which sewage is
not desire by irrigators. we have asked and
| received statement thereof from Mr.. Henry
Mariz, President of the South side Irrigation
Company, showing that since the summer Of
| 1888 the sewage had to be run to waste during
the following periods:
From November 13, 1888, to February ID,
1889. SO days. no sewage was used.
From February 14th to March 13, 1889, 20
days, one-half of the sewage was used. (Aboue
81 cubic feet per second on $50 acres. or
3,480 gallons per day per acre).
From March 18th to April 20. 1889, 80 days,
From April Goth to September 80, 1889, 1853
days, all the sewage was used. (About cubic
feet per second on 1,7O0 acres. or 3,04O gallons
per day per acre.
From september Both to October 20, 1889,
20 days, oae-third of the sewage was used
About cubic feet per second on 1,7O0 acres,
or i, lao gallons per day per acre.)
October 2Oth to December 10, 1889, Sc days,
no sewage was used.
Therefore, between October 20, 1888. and
October 20. 1889. IN 1877 days ali sewage was
used; for &c days one.half of it; for 20 days
only onerthird of 1t, and for 132 days none was
used.
80, 1889. on 267 days, all the sewage W IS used !;
for 26 days one half OF it. and for 132 days no
sewage was used.
During wet year the number of days when
the water takers do not want the sewage IL still
greater. But for the purpose of a comparative
estimate OF cost we have assumed an average
time of 13O days per annum during which the
sewage must be disposed of by other methods
than the present one.
Land cannot be properly cultivated which
must receive sewage at all seasons. The crops
at certain stages of growth will be positively In
jured by irrigation. The greatest benefit is
derived by land owners If they are placed in
such position that they can take the sewage
sire. Under such circumstances land can be
rented at higher rates than otherwise, and con-
81 Quently sewage water can be sold at much
better prices to the irrigators.
We will next consider the daily quantity of
sewage to be dealt with 1t will consist partly
OF waste water from buildings. partly of water
used for flushing the sewers. andNpartly of sub
soil water entering the sewer accidentally from
leaks or from wet ground
The amount of house water is usually found
to be very nearly equal to the amount of water
used for domestic supply, which in this city is
estimated to be lis gallons per head per day.
The quantity used for flushing is comparatively
small, and, as 1t can be controlled and confined
to the time OF low flow, 1t need rot be con-
sidered. The subsoil or ground water entering
sewers ID quite variable in quantity, and de-
Ponds on the season. on the locality and
ihe care with which the sewers are
built. The latter Is the most important con-
ditiOD, aud 1t cannot be too strip gently
urged in every case where expensive outfall
sewers or disposal works must be provided,
that great care should begsven to the construc-
tion of the sewers with view of m king them
wster-tight. Numerous instances are on rec
ord where, even with the utmost care, the soil
water collected was considerable. In Prov.-
dence, r. /. It was found to be AZ gallons per
day per inhsbitant; in Orange, N j., about 33
per cent. in Kalamazoo, Mich, 20 per cent.
of the capacity of the sewers; in Norwalk, VT,
1t Is at least go per cent; In Stamford, Conn.
80 per cent in Schenectady, NY, about per
cent. of the capacity of the mains.
From gaugings made by some members of
the commission, If the flow In the outfall
sewer in San Pedro street near Wilmington
street, before the recent heavy rains, 1t was
