At the time of my visit to Albuquer-

business part OF the city in the lower
ground, were filled with sewage. due

outlet, consequently It was impossible
to make thorough examination OF
the sewers at that time.
The present sewers, especially the
trunk lines, are laid With very nat
grades which give low velocity of
flow in the sewers. In some instances
dcprcssions occur in the main trunk
line, some of which may be due TO
its having settled since It was built;
consequently the sewers generally
have become partially filled with solid
matters After the temporary pump

built is in operation, the conditions

The present system was designed
for domestic sewage only, storm
water being excluded; but the main
sewer on the West Side takes in

sewer districts. That portion OF the
city lying on the west side Of the
Santa Fe tracks Is low and with very
little grade, while that portion located
on the east side OF the railroad,
known as the Highlands" is on
higher ground, with rapidly rising
grades towards the east
In considering a complete system
OF sewerage for your city. 1t Is ad-
vlsabe to take advantage OF these
conditions and consider the two sec
tons OF the city separately. which. in
this report viii be designated as the
East Side and the West side districts
The area contained within the en-
tire city limits is approximately 1000
acres. 4 tract OF 900 acres lying on

Systems OF Sewerage.
In discussing the sewerage propo-
sition, il may be well TO call atten-
ton to some of the various systems
OF sewerage, as wen as some of tho
methods OF sewage disposal now In
use.
There are three general systems OF
sewerage in use, which are known as
the separate system. the combined
system and the double system.
Flrst-"The separate system" OF
sewerage is intended to take only do.
mestic sewage from dwellings, hotels
and other places OF habitation, and a
certain quantity of manufacturing
liquid wastes. No storm water or
r1in-watcr IS allowed TO enter tho
sewers.
Second-"Conbined System" The |
combined system Of sewerage is in |
tended TO take all domestic sewage
and more or less Of the storm water |
accumulating on the area being sew-
cred. This system requires large |
sewers in order to provide for the |
sudden downpour OF rain. which Of
ten occurs in a short space OF time |
This system is much moro expensive |

IL requires larger sewers. with catch |
basins at frequent intervals. 10 inteI

Third-The Double System" This /
system Includes the building OF two /
systems, one for sewage only. and ono |
for storm-water. While this system o. I
